Safety recommendations

To avoid equipment damage or bodily injury, read the following safety recommendations before installation. Note that the recommendations do not cover every possible hazardous condition.

·     Before cleaning the switch, remove all power cords from the switch. Do not clean the switch with wet cloth or liquid.

·     Do not place the switch near water or in a damp environment. Prevent water or moisture from entering the switch chassis.

·     Do not place the switch on an unstable case or desk.

·     Ensure good ventilation at the installation site and keep the air inlet and outlet vents of the switch free of obstruction.

·     Make sure the power source voltage is as required.

·     To avoid electrical shocks, do not open the chassis while the switch is operating or when the switch is just powered off.

·     To avoid ESD damage, wear an ESD wrist strap to hot-swap a power supply.

Examining the installation environment

To ensure correct operation of your switch, make sure the installation environment meets the requirements listed in Table1-2.

Table1-2 Checking list for the installation environment

Item	Requirements
Ventilation and heat dissipation	CAUTION: To ensure correct operation of your device, make sure the installation environment is adequately ventilated to prevent the switch from overheating. ·     Ensure a minimum clearance of 10 cm (3.94 in) around the chassis. ·     Do not install the device near a heat source, for example, a stove or heater. ·     Ensure air ventilation in the installation environment. ·     Do not block the ventilation holes in the device or power adapter.
Anti-moisture	CAUTION: Water or moisture might damage the circuits of the device. ·     Do not place the device near water or in a damp environment. ·     Install the switch in a clean, dry, and ventilated place where temperature is controlled in a stable range. ·     Make sure the installation environment is free from water leakage or condensation. If required, install a dehumidification device (such as an air conditioner with a dehumidification function or a dedicated dehumidifier). ·     Do not operate the device under or near the water source, such as the wash basin, laundry room, or areas with high humidity. ·     Do not touch the device with wet hands.
Hot surface	Hot surface. Use caution when working near the hot surface. If the switch has a hot surface sign , the switch is intended for installation in a restricted access area. A restricted access area can be accessed by skilled, instructed, or qualified personnel.
Temperature/humidity	For correct operation and long service life of your switch, maintain the temperature and humidity in the equipment room at acceptable ranges. ·     Lasting high relative humidity can cause poor insulation, electricity leakage, mechanical property change of materials, and metal corrosion. ·     Lasting low relative humidity can cause washer contraction and ESD and cause issues including loose mounting screws and circuit failure. ·     High temperature can accelerate the aging of insulation materials and significantly lower the reliability and lifespan of the switch. For the temperature and humidity requirements of the switch, see technical specifications in FS5100-EI Switch Series Hardware Information and Specifications.
Lightning protection	CAUTION: Ground the switch correctly and verify the grounding. For more information, see "Grounding the switch." ·     If you ground the switch by using a grounding strip, make sure the grounding resistance of the grounding strip in the equipment room is less than 1W. ·     If you ground the switch by using a grounding conductor buried in the earth ground, make sure the grounding resistance of the grounding conductor in the ground is less than 10W. ·     Route the signal cables along indoor walls, bury the cables in the earth ground, or thread the cables through steel tubes. Install a signal lightning arrester with a nominal discharge current for a corresponding network interface. ·     Keep the signal cables far from power cords and lightning rod down conductors. ·     As a best practice, route power cords indoors. If an AC power cord is routed from outdoors, connect the AC power cord first to a power lightning arrester before leading it to the AC power port on the switch. Make sure the power lightning arrester has a nominal discharge current and the total length of the power cord from the power lighting arrester to the power port on the switch is less than 5 m (16.40 ft). ·     Ground the switch, rack, independent power supplies, and lightning arresters separately. ·     You must ground optical fibers with reinforcing metal stiffener from outdoors on an optical distribution frame (ODF) or fiber splice enclosure.
Cable routing	CAUTION: Do not run an Ethernet cable and power cord in parallel. ·     Route different types of cables separately. ·     Keep power cords a minimum of 5 cm (1.97 in) away from other cables.
ESD prevention	·     Ground the switch correctly. ·     To avoid ESD damage to the device or components, always wear an ESD wrist strap when you install or remove the device or components. ·     Make sure the wrist strap has good skin contact and is reliably grounded.
Cleanliness	·     For more information, see "Cleanliness."
Corrosive gas prevention	The installation site must be free from corrosive gases such as acid gases and alkaline gases. For more information, see "Corrosive gas limit."
EMI	·     If AC power is used, use a single-phase three-wire power receptacle with protection earth (PE) to filter interference from the power grid. ·     Keep the device far away from radio transmitting stations, radar stations, and high-frequency devices. ·     Use electromagnetic shielding, for example, shielded interface cables, when necessary.

 

Cleanliness

Dust buildup on the chassis might cause electrostatic adsorption and dust corrosion, resulting in poor contact of metal connectors and contact points. This might shorten the device's lifetime and even cause device failure in the worst case. Table1-3 describes the switch requirement for cleanliness.

Table1-3 Switch requirement for cleanliness

Substance	Particle diameter	Concentration limit
Dust particles	≥ 0.5 µm	≤ 1.8 × 107 particles/m3

 

To maintain cleanliness in the equipment room, follow these guidelines:

·     Keep the equipment room away from pollution sources. Do not smoke, eat, or drink in the equipment room.

·     Use double-layer glass in windows and seal doors and windows with dust-proof rubber strips. Use screen doors and window screens for doors and windows open to the outside and make sure the external windows are air tight.

·     Use dustproof materials for floors, walls, and ceilings and use wallpaper or matt paint that does not produce powders.

·     Clean the equipment room regularly and clean the air filters of the rack each month.

·     Wear ESD clothing and shoe covers before entering the equipment room, keep the ESD clothing and shoe covers clean, and change them frequently.

Corrosive gas limit

Corrosive gases can accelerate corrosion and aging of metal components. Make sure the corrosive gases do not exceed the concentration limits as shown in Table1-4.

Table1-4 Corrosive gas concentration limits

Gas	Average concentration (mg/m3)	Maximum concentration (mg/m3)
SO2	0.3	1.0
H2S	0.1	0.5
Cl2	0.1	0.3
HCI	0.1	0.5
HF	0.01	0.03
NH3	1.0	3.0
O3	0.05	0.1
NOX	0.5	1.0

 

	CAUTION: As a best practice, control the corrosive gas concentrations in the equipment room at their average values. Make sure the corrosive gas concentrations do not exceed 30 minutes per day at their maximum values.

 

To control corrosive gases, use the following guidelines:

·     As a best practice, do not build the equipment room in a place with a high concentration of corrosive gases.

·     Make sure the equipment room is not connected to sewer, vertical shaft, or septic tank pipelines and keep it far away from these pipelines. The air inlet of the equipment room must be away from such pollution sources.

·     Use environmentally friendly materials to decorate the equipment room. Avoid using organic materials that contains harmful gases, such as sulfur or chlorine-containing insulation cottons, rubber mats, sound-proof cottons, and avoid using plasterboards with high sulfur concentration.

·     Place fuel (diesel or gasoline) engines separately. Do not place them in the same equipment room with the device. Make sure the exhausted air of the engines will not flow into the equipment room or towards the air inlet of the air conditioners.

·     Place batteries separately. Do not place them in the same room with the device.

·     Employ a professional company to monitor and control corrosive gases in the equipment room regularly.

Grounding the switch

	WARNING! Correctly connecting the switch grounding cable is crucial to lightning protection, ESD, and EMI protection. For information about lightning protection, see H3C Network Devices Lightning Protection Guide.

 

To protect against the following types of issues, use a grounding cable to connect the switch to the earthing facility at the installation site:

·     Bodily injury from electric shocks.

·     Device and power and data line damages.

·     Electrical fires, lightning strokes, electromagnetic coupling interferences, and ESD damages.

You can ground the switch in one of the following ways, depending on the grounding conditions available at the installation site:

·     Grounding the switch by using a grounding strip

·     Grounding the switch with a grounding conductor buried in the earth ground

 

	NOTE: The chassis views and power supply and grounding terminal positions in the following figures are for illustration only.

 

Grounding the switch by using a grounding strip

	WARNING! Connect the grounding cable to the grounding system in the equipment room. Do not connect it to a fire main or lightning rod.

 

If a grounding strip is available at the installation site, use the grounding strip to ground the switch.

To ground the switch by using a grounding strip:

1.     Attach the ring terminal end of the grounding cable to the grounding hole in the switch.

a.     Remove the grounding screw from the grounding hole in the rear panel of the switch.

b.     Attach the grounding screw to the ring terminal of the grounding cable.

c.     Use a screwdriver to fasten the grounding screw into the grounding screw hole.

2.     Connect the other end of the grounding cable to the grounding strip.

a.     Use the needle-nose pliers to bend the bare wire.

b.     Hook the grounding cable to the post on the grounding strip, and use the hex nut to secure the cable to the post.

Grounding the switch with a grounding conductor buried in the earth ground

If the installation site does not have grounding strips, but earth ground is available, hammer a 2.5 m (8.20 ft) or longer angle iron or steel tube into the earth ground to act as a grounding conductor. Make sure a minimum of 0.7 m (2.30 ft) is left between the top of the grounding conductor and the ground. In cold areas, bury the grounding conductor below the frozen soil layer. In areas with thin soil or rocky gravel, determine the depth for burying the grounding conductor based on the actual condition.

If zinc-coated steel is used, the following dimensions requirements must be met:

·     Angle iron—A minimum of 50 × 50 × 5 mm (1.97 × 1.97 × 0.20 in).

·     Steel tube—A minimum of 3.5 mm (0.14 in) in thickness.

·     Flat steel—A minimum of 40 × 4 mm (1.57 × 0.16 in).

·     Round steel—A minimum of 10 mm (0.39 in).

Weld the yellow-green grounding cable to the angel iron or steel tube and treat the joint for corrosion protection.

Verifying the connection after grounding the switch

·     If you ground the switch with a grounding strip:

a.     Use a multimeter to measure the resistance between the switch grounding terminal and grounding point, and make sure the resistance is less than 0.1W.

b.     Use a grounding resistance tester to measure the grounding resistance of the grounding strip, and make sure the grounding resistance is less than 1W.

·     If you ground the switch with a grounding conductor buried in the earth ground:

a.     Use a multimeter to measure the resistance between the switch grounding terminal and grounding point, and make sure the resistance is less than 0.1W.

b.     Use a grounding resistance tester to measure the grounding resistance of the angle iron in the ground, and make sure the grounding resistance is less than 10W. For locations with high soil resistivity, sprinkle some resistance reducer to reduce soil resistivity or replace soil around the grounding strip with soil with lower resistance.

For information about resistance measurement, see H3C Network Devices Lightning Protection Guide.

Installing and removing power supplies

	CAUTION: Provide a circuit breaker for each power supply and make sure the circuit breaker is off before installation.

 

Only the FS5100-52F-EI-PS supports removable power supplies.

The FS5100-52F-EI-PS provides two power supply slots. It comes with power supply slot 1 empty and power supply slot 2 installed with a filler panel. You can install one power supply, or two power supplies for redundancy. For information about power supplies available for the switch, see removable components in FS5100-EI Switch Series Hardware Information and Specifications.

When two power supplies are installed, you can hot-swap a power supply. To avoid device damage and bodily injury, follow the procedures in Figure2-23 and Figure2-24 to install and replace a power supply.

Figure2-23 Installation procedure

 

Figure2-24 Removal procedure

 

The installation and removal procedures are the same for power supplies. This guide uses the PSR920-54A-B power supply as an example.

Installing a power supply

1.     Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.

2.     Unpack the power supply and verify that the power supply model is as required.

3.     Remove the filler panel (if any) from the target slot.

If you require only one power supply, install it in power supply slot 1 and make sure a filler panel is installed in power supply slot 2.

Figure2-25 Removing the filler panel

 

4.     Orient the power supply with the upside up. Grasp the handle of the power supply with one hand and support its bottom with the other, and slide the power supply slowly along the guide rails into the slot.

To prevent damage to the power supply and the connector on the switch backplane, insert the power supply gently. If you encounter a hard resistance or the power supply tilts while inserting the power supply, pull out the power supply, realign it with the slot, and then insert it again.

Figure2-26 Installing a power supply

 

Removing a power supply

1.     Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.

2.     Power off the power supply and remove the power cord.

3.     Press the latch towards the handle, and pull the power supply along the guide rails until it is part-way out.

4.     Grasp the handle of the power supply with one hand and pull the module part way out. Support the module bottom with the other hand, and pull the power supply slowly along the guide rails out of the slot.

5.     Place the removed power supply in an antistatic bag.

Connecting the power cord

	CAUTION: ·     Provide a circuit breaker for each power cord. ·     Before connecting the power cord, make sure the circuit breaker on the power cord is turned off.

 

The FS5100-8T2RS-EI, FS5100-8T2RX-EI, FS5100-8P2RS-EI, and FS5100-8P2RX-EI switches do not come with power cords. As a best practice, use these models at the endpoint access side with hybrid copper-fiber cables and terminal blocks in the iOptic scenario. To use these switch models independently, select matching power adapters for them. For information about using hybrid copper-fiber cables and device deployment in the iOptic scenario, see H3C iOptic Hardware Deployment Guide.

·     The grounding cable is securely connected.

·     The correct power source is used.

·     The power cords are correctly connected.

·     All the interface cables are cabled indoors. If any cable is routed outdoors, verify that the socket strip with lightning protection and lightning arresters for network ports have been correctly connected.

 

3 Accessing the switch for the first time

Connecting the switch to a configuration terminal

The switch provides a serial console port.

In Figure3-1, the switch is connected to a configuration terminal (PC as an example) from the serial console port.

Figure3-1 Connecting the switch to a configuration terminal

 

As shown in Figure3-1, two types of console cables can be used for connecting the switch to a configuration terminal. The switch is not provided with a serial console cable.

Table3-1 Connection methods and console cables

Connection method	Console cable type	Configuration terminal-side connector	Switch-side connector
Using the serial console port for connection	DB9-to-RJ45 console cable	DB-9 female connector	RJ-45 connector
	USB-to-RJ45 console cable	USB connector	RJ-45 connector

 

The signal pinout for the RJ-45 connector of a serial console cable varies by vendor. To avoid abnormal configuration terminal display, use a serial console cable provided by H3C. To prepare a serial console cable yourself, make sure the signal pinout for the RJ-45 connector is the same as that shown in Table3-2.

Connecting a DB9-to-RJ45 console cable

	CAUTION: Follow these guidelines when you connect a DB9-to-RJ45 console cable: ·     Identify the mark on the serial console port and make sure you are connecting to the correct port. ·     The serial ports on PCs do not support hot swapping. To connect a PC to an operating switch, first connect the PC end. To disconnect a PC from an operating switch, first disconnect the switch end.

 

A DB9-to-RJ45 serial console cable is an 8-core shielded cable, with a crimped RJ-45 connector at one end for connecting to the serial console port of the switch, and a DB-9 female connector at the other end for connecting to the serial port on a configuration terminal.

Figure3-2 DB9-to-RJ45 console cable

 

Table3-2 DB9-to-RJ45 console cable signal pinout

RJ-45	Signal	DB-9	Signal
1	RTS	8	CTS
2	DTR	6	DSR
3	TXD	2	RXD
4	SG	5	SG
5	SG	5	SG
6	RXD	3	TXD
7	DSR	4	DTR
8	CTS	7	RTS

 

To connect the switch to a configuration terminal (for example, a PC) by using a DB9-to-RJ45 console cable:

1.     Plug the DB-9 female connector of the DB9-to-RJ45 console cable to the serial port on the PC.

2.     Connect the RJ-45 connector to the serial console port on the switch.

Connecting a USB-to-RJ45 console cable

IMPORTANT: ·     To use a USB-to-RJ45 console cable to connect the switch to a configuration terminal, first download and install the USB-to-RJ45 console driver on the configuration terminal and then connect the USB-to-RJ45 console cable to the configuration terminal. ·     If you have connected a USB-to-RJ45 console cable to the configuration terminal before installing the driver, remove and reconnect the USB-to-RJ45 console cable to the configuration terminal after driver installation.

 

For information about the signal pinout for the RJ-45 connector of a USB-to-RJ45 console cable, see Table3-2.

The following installs the driver on the Windows system. To install the driver on other operating systems, see the installation guide in the driver compression package named by using the corresponding operating system.

To connect the switch to a configuration terminal by using a USB-to-RJ45 console cable:

1.     Click the following link, or copy it to the address bar on your browser and download the USB-to-RJ45 console driver.

http://www.h3c.com/en/home/USB_to_RJ45_Console/

2.     View the TXT file Read me in the Windows folder to check whether the Windows system of the configuration terminal supports the driver.

3.     If the Windows system supports the driver, install PL23XX-M_LogoDriver_Setup_v200_20190815.exe.

4.     Click Next on the welcome page of the driver installation wizard.

Figure3-3 Driver installation wizard

 

5.     Click Finish after the drive installation is completed.

Figure3-4 Finishing the driver installation

 

6.     Connect the standard USB connector of the cable to the USB port of the configuration terminal.

7.     Connect the RJ-45 connector of the cable to the console port of the switch.

Setting terminal parameters

To configure and manage the switch through the console port, you must run a terminal emulator program, such as TeraTermPro, on your configuration terminal. You can use the emulator program to connect a network device, a Telnet site, or an SSH site. For more information about the terminal emulator programs, see the user guides for these programs.

Configure the terminal parameters as follows:

·     Bits per second—9,600.

·     Data bits—8.

·     Stop bits—1.

·     Parity—None.

·     Flow control—None.

Powering on the switch

Before powering on the switch, verify that the following conditions are met:

·     The power cord is correctly connected.

·     The input power voltage meets the requirement of the switch.

·     The console cable is correctly connected.

·     The configuration terminal (a PC, for example) has started, and its serial port settings are consistent with the console port settings on the switch.

During the startup process, you can access Boot ROM menus to perform tasks such as software upgrade and file management. The Boot ROM interface and menu options differ with software versions. For more information about Boot ROM menu options, see the software-matching release notes for the device.

After the startup completes, you can access the CLI to configure the switch.

For more information about the configuration commands and CLI, see the configuration guides and command references for the switch series.

4 Setting up an IRF fabric

You can use H3C IRF technology to connect and virtualize the switches into a large virtual switch called an "IRF fabric" for flattened network topology, and high availability, scalability, and manageability.

IRF fabric setup flowchart

Figure4-1 IRF fabric setup flowchart

 

To set up an IRF fabric:

 

Step	Description
1.     Plan IRF fabric setup.	Plan the installation site and IRF fabric setup parameters: ·     Planning IRF fabric size and the installation site ·     Identifying the master switch and planning IRF member IDs ·     Planning IRF topology and connections ·     Identifying IRF physical ports on the member switches ·     Planning the cabling scheme
2.     Install IRF member switches.	See "Installing the switch in a 19-inch rack" or "Mounting the switch on a workbench."
3.     Connect grounding cables and power cords.	See "Grounding the switch" and "Connecting the power cord."
4.     Power on the switches.	N/A
5.     Configure basic IRF settings.	See the IRF configuration guide or virtual technologies configuration guide for the switch series, depending on the software version.
6.     Connect the IRF physical ports.	Connect IRF physical ports on switches. All switches except the master switch automatically reboot, and the IRF fabric is established.

 

Planning IRF fabric setup

This section describes issues that an IRF fabric setup plan must cover.

Planning IRF fabric size and the installation site

Choose switch models and identify the number of required IRF member switches, depending on the user density and upstream bandwidth requirements. The switching capacity of an IRF fabric equals the total switching capacities of all member switches.

Plan the installation site depending on your network solution, as follows:

·     Place all IRF member switches in one rack for centralized high-density access.

·     Distribute the IRF member switches in different racks to implement the ToR access solution for a data center.

Identifying the master switch and planning IRF member IDs

Determine which switch you want to use as the master for managing all member switches in the IRF fabric. An IRF fabric has only one master switch. You configure and manage all member switches in the IRF fabric at the CLI of the master switch. IRF member switches automatically elect a master. You can affect the election result by assigning a high member priority to the intended master switch. For more information about master election, see the IRF configuration guide or virtual technologies configuration guide for the switch series, depending on the software version.

Prepare an IRF member ID assignment scheme. An IRF fabric uses member IDs to uniquely identify and manage its members, and you must assign each IRF member switch a unique member ID.

Planning IRF topology and connections

You can create an IRF fabric in daisy chain topology or more reliable ring topology. In ring topology, the failure of one IRF link does not cause the IRF fabric to split as in daisy chain topology. Instead, the IRF fabric changes to a daisy chain topology without interrupting network services.

You connect the IRF member switches through IRF ports, the logical interfaces for the connections between IRF member switches. Each IRF member switch has two IRF ports: IRF-port 1 and IRF-port 2. To use an IRF port, you must bind at least one physical port to it.

When connecting two neighboring IRF member switches, you must connect the physical ports of IRF-port 1 on one switch to the physical ports of IRF-port 2 on the other switch.

The switch can form an IRF fabric only with switches from the same switch series. For the physical ports that can be used for IRF connections and the restrictions for using the ports, see Table4-1. The IRF physical ports can set up IRF connections only when operating at their highest speeds. For example, a 10-GE port must operate at 10 Gbps. A 1-GE port must operate at 1 Gbps.

You can bind multiple ports to an IRF port for increased bandwidth and availability.

 

	NOTE: The following figures use the SFP+ ports on the FS5100-12S-EI switch as an example. For the ports that can be used for IRF connections, see Table4-1.

 

Figure4-2 IRF fabric in daisy chain topology

 

Figure4-3 IRF fabric in ring topology

 

Identifying IRF physical ports on the member switches

Identify the IRF physical ports on the member switches according to your topology and connection scheme.

Table4-1 shows the physical ports that can be used for IRF connection and the port use restrictions.

Table4-1 IRF physical ports and use restrictions

Device model	Candidate IRF physical ports	Restrictions for using the ports for IRF connections
FS5100-8T2RS-EI FS5100-8T2RX-EI FS5100-8P2RS-EI FS5100-8P2RX-EI	All the following ports on the front panel: ·     PSFP ports and PSFP+ ports ·     10/100/1000BASE-T autosensing Ethernet ports	All physical ports to be bound to an IRF port must have the same data rate. The port must operate at the following speed. ·     PSFP port—1 Gbps ·     PSFP+ port—10 Gbps ·     10/100/1000BASE-T autosensing port + SFP+ port—1 Gbps
FS5100-8S-PWR-EI FS5100-12S-EI FS5100-12S-PWR-EI FS5100-52F-EI-PS	All the following ports on the front panel: ·     SFP+ ports ·     10/100/1000BASE-T autosensing ports	All physical ports to be bound to an IRF port must have the same data rate. The port must operate at the following speed. ·     SFP+ port—10 Gbps ·     10/100/1000BASE-T autosensing port + SFP+ port—1 Gbps
FS5100-12MS-EI FS5100-12MS-PWR-EI FS5100-20MS-EI FS5100-20MS-PWR-EI	All the following ports on the front panel: ·     5G/2.5G/1000/100BASE-T autosensing Ethernet ports ·     10/100/1000BASE-T autosensing Ethernet ports ·     SFP+ ports	All physical ports to be bound to an IRF port must have the same data rate. The port must operate at the following speed. ·     SFP+ port—10 Gbps ·     5G/2.5G/1000/100BASE-T autosensing port + SFP+ port—5 Gbps ·     10/100/1000BASE-T autosensing port + SFP+ port—1 Gbps

 

Planning the cabling scheme

Use the following cables to connect the IRF physical ports on the switches:

·     10/100/1000BASE-T autosensing Ethernet port—Category 5 or above twisted-pair cable.

·     5G/2.5G/1000/100BASE-T autosensing Ethernet port—Category 5e or above twisted-pair cable.

·     PSFP/SFP port—GE SFP fiber transceiver module and optical fiber, GE SFP copper transceiver module and twisted pair cable or GE SFP cable. For the available transceiver models and cables, see ports in FS5100-EI Switch Series Hardware Information and Specifications.

·     PSFP+/SFP+ port—SFP+ fiber transceiver module and optical fiber or SFP+ cable. For the available transceiver models and cables, see ports in FS5100-EI Switch Series Hardware Information and Specifications.

If the IRF member switches are far away from one another, use SFP/SFP+ transceiver modules and optical fibers. If the IRF member switches are all in one equipment room, use twisted pair cables or SFP/SFP+ cables.

As a best practice, use ring topology to connect the switches. The following describes cabling schemes in ring topology.

Connecting the IRF member switches in one rack

Use SFP cables to connect the IRF member switches in a rack as shown in Figure4-4. The switches in the ring topology (see Figure4-5) are in the same order as connected in the rack.

Figure4-4 Connecting the switches in one rack

 

Figure4-5 IRF fabric topology

 

Connecting the IRF member switches in a ToR solution

You can install IRF member switches in different racks side by side to deploy a top of rack (ToR) solution.

Figure4-6 shows an example for connecting four top of rack IRF member switches by using SFP transceiver modules and optical fibers. The topology is the same as Figure4-5.

Figure4-6 ToR cabling

 

Configuring basic IRF settings

After you install the IRF member switches, power on the switches, and log in to each IRF member switch (see the fundamentals configuration guide for the switch series) to configure their member IDs, member priorities, and IRF port bindings.

Follow these guidelines when you configure the switches:

·     Assign the master switch higher member priority than any other switch.

·     Bind physical ports to IRF port 1 on one switch and to IRF port 2 on the other switch. You perform IRF port binding before or after connecting IRF physical ports depending on the software release.

·     Execute the display irf configuration command to verify the basic IRF settings.

For more information about configuring basic IRF settings, see the IRF configuration guide or virtual technologies configuration guide for the switch series, depending on the software version.

Connecting the IRF physical ports

Use twisted pair cables, SFP/SFP+ cables, or SFP/SFP+ transceiver modules and fibers to connect the IRF member switches as planned.

Wear an ESD wrist strap when you connect twisted pair cables, SFP/SFP+ cables, or SFP/SFP+ transceiver modules and fibers. For how to connect them, see H3C Transceiver Modules User Guide.

Verifying the IRF fabric setup

To verify the basic functionality of the IRF fabric after you finish configuring basic IRF settings and connecting IRF ports:

1.     Log in to the IRF fabric through the console port of any member switch.

2.     Create a Layer 3 interface, assign it an IP address, and make sure the IRF fabric and the remote network management station can reach each other.

3.     Use Telnet or SNMP to access the IRF fabric from the network management station. (See the fundamentals configuration guide for the switch series.)

4.     Verify that you can manage all member switches as if they were one node.

5.     Display the running status of the IRF fabric by using the commands in Table4-2.

	NOTE: To avoid IP address collision and network problems, configure a minimum of one multi-active detection (MAD) mechanism to detect the presence of multiple identical IRF fabrics and handle collisions. For more information about MAD detection, see the IRF configuration guide or virtual technologies configuration guide for the switch series, depending on the software version.

 

5 Maintenance and troubleshooting

Fixed power supply failure

To identify a power failure on a switch with fixed power supplies, examine the system status LED (SYS) on the switch. If the system LED is off, an AC power input failure has occurred.

Symptom

The system status LED is off. An AC input failure has occurred.

Solution

To resolve the issue:

1.     Verify that the AC power cord is correctly connected to the switch.

2.     Verify that the AC-input power receptacle on the switch and the connected AC power outlet are in good condition.

3.     Verify that the AC power source is operating correctly.

4.     Verify that the operating temperature of the switch is in the acceptable range, and the power supply has good ventilation. Overtemperature can cause the power supply to stop working and enter protection mode.

5.     If the issue persists, contact H3C Support.

Removable power supply failure

The FS5100-52F-EI-PS switch uses removable power supplies. You can determine the power supply operating status by examining the power supply LEDs PWR1 and PWR2 on the switch front panel. For descriptions about the PWR1 and PWR2 LEDs, see LEDs in Hardware Information and Specifications. For more information about the LEDs on the power supplies, see H3C PSR920-54A-B Power Supply User Manual-APW100.

Symptom

A power supply LED on the front panel of the switch is not steady green.

Solution

To resolve the issue:

1.     Verify that the power cord is correctly connected to the switch.

2.     Verify that the power supply model is as required.

3.     Verify that the power supply is installed correctly in the switch.

4.     Verify that the switch is operating in the acceptable temperature range.

5.     If the power supply needs to be replaced, see "Installing and removing power supplies" to replace the power supply.

6.     If the issue persists, contact H3C Support.

Fan tray failure

Symptom

The system status LED on the switch indicates a fan tray failure.

Solution

When a fan tray issue occurs, contact H3C Support.

Configuration terminal issues

No display on the configuration terminal

Symptom

The configuration terminal does not have display when the switch is powered on.

Solution

To resolve the issue:

1.     Verify that the power system is operating correctly.

2.     Verify that the switch is operating correctly.

3.     Verify that the console cable has been connected correctly.

4.     Verify that the following settings are configured for the terminal:

¡     Baud rate—9600.

¡     Data bits—8.

¡     Parity—None.

¡     Stop bits—1.

¡     Flow control—None.

5.     Verify that the console cable is not faulty.

6.     If the issue persists, contact H3C Support.
