· 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. The switch might be severely damaged in case of a fall.

· Ensure good ventilation of the equipment room and keep the air inlet and outlet vents of the switch free of obstruction.

· Make sure the power input voltage is as required by the power supply.

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

· Wear an ESD wrist strap when you replace an expansion card, removable power supply, or fan tray. Make sure the strap makes good skin contact and is reliably grounded.

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.
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 the hardware information and specifications for the switch.
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 FRUs, always wear an ESD wrist strap when you install or remove the device or FRUs. · 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.

3 Accessing the switch for the first time

Connecting the switch to a configuration terminal

The switch provides a serial console for connecting to a configuration terminal.

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 Table3-1, two types of console cables can be used for connecting the switch to a configuration terminal.

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
Using the serial console port for connection	USB-to-RJ45 console cable	USB connector	RJ-45 connector

The signal pinout for a DB9-to-RJ45 console cable depends on the vendor of the cable. To avoid abnormal configuration terminal display, use a serial console cable provided by H3C. For more information, see Table1-8. 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 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 the console 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) through 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 driver installation, you must remove and reconnect the USB-to-RJ45 console cable to the configuration terminal.

Figure3-3 USB-to-RJ45 console cable

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 the corresponding operating system.

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—9600.

· Data bits—8.

· Parity—None.

· Stop bits—1.

· Flow control—None.

Starting the switch

Pre-start checklist

Before powering on the switch, verify the following items:

· The power cord is correctly connected.

· The input power voltage is as required by the switch.

· The console cable is correctly connected.

· The PC has started, and the terminal parameters have been correctly configured.

Powering 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 process is completed, you can access the CLI to configure the switch.

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

4 Setting up an IRF fabric

You can use H3C IRF technology to connect and virtualize S5590-HI, S5590-EI, or S5500V3-HI switches into a large virtual switch called an "IRF fabric" for flattened network topology, and high availability, scalability, and manageability.

A switch can set up an IRF fabric only with switches from the same switch series.

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 physical IRF 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 Virtual Technologies Configuration Guide for the switch series.
6. Connect the physical IRF ports	Connect physical IRF 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.

NOTE:

For the maximum IRF member devices supported by the switch, see the release notes that come with the switch.

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 Virtual Technologies Configuration Guide for the switch.

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 a minimum of 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. See Table4-1 for the available IRF physical ports. You can bind several IRF physical ports to an IRF port for increased bandwidth and availability.

Figure4-2 and Figure4-3 show the topologies of an IRF fabric made up of three S5590-28T8XC-HI switches. The IRF port connections in the two figures are for illustration only, and more connection methods are available.

Figure4-2 IRF fabric in daisy chain topology

Figure4-3 IRF fabric in ring topology

Identifying physical IRF ports on the member switches

Identify the physical IRF 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 Candidate physical IRF ports and their use restrictions

Chassis	Candidate physical IRF ports	Use restrictions
S5590-HI & S5590-EI & S5500V3-HI	· SFP+ ports on the front panel · Ports that can be provided by the expansion card on the rear panel: ¡ SFP+ ports except for those on the LSWM2SP2PB and LSWM2SP4PB ¡ SFP28 ports ¡ QSFP+ ports ¡ QSFP28 ports	· All physical ports to be bound to an IRF logical interface must have the same data rate. · Physical ports on interface cards and the front panel can be bound to the same IRF port. · An SFP+ port can be used as an IRF physical port only when it operates at 10 Gbps. · An SFP28 port can be used as an IRF physical port only when it operates at 25 Gbps. · A QSFP+ port can be used as an IRF physical port only when it operates at 40 Gbps. · A QSFP28 port can be used as an IRF physical port only when it operates at 40 or 100 Gbps.

· A QSFP+ port can be used as an IRF physical port only when it operates at 40 Gbps.

· A QSFP28 port can be used as an IRF physical port only when it operates at 40 or 100 Gbps.

Planning the cabling scheme

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

· SFP+ port—SFP+ fiber transceiver module and optical fiber or SFP+ cable. For the available transceiver models and cables, see ports in the hardware information and specifications for the switch.

· SFP28 port—SFP28 fiber transceiver module and optical fiber or SFP28 cable. For the available transceiver models and cables, see ports in the hardware information and specifications for the switch.

· QSFP+ port—QSFP+ fiber transceiver module and optical fiber or QSFP+ cable. For the available transceiver models and cables, see ports in the hardware information and specifications for the switch.

· QSFP28 port—QSFP28/QSFP+ fiber transceiver module and optical fiber or QSFP28/QSFP+ cable. For the available transceiver models and cables, see ports in the hardware information and specifications for the switch.

For a short-distance IRF connection in an equipment room, use an SFP+/SFP28/QSFP+/QSFP28 cable.

For a long-distance IRF connection, use SFP+/SFP28/QSFP+/QSFP28 transceiver modules and optical fibers.

The following subsections describe several H3C recommended IRF connection schemes by using SFP+ cables and SFP+ transceiver modules and fibers. All these schemes use a ring topology.

IMPORTANT:

In these schemes, all physical IRF ports are located on the same side. If physical IRF ports are on different sides, you must measure the distance between them to select an appropriate cable.

Connecting the IRF member switches in one rack

Connect the IRF member switches (4 switches in this example) 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 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 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.

· To bind the ports on an interface module to an IRF port, you must install the interface module first.

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

For the S5590-48T4XC-HI and S5590-48S4XC-HI switches, you can use the port-speed-mode command to configure the port rate mode for an expansion slot. By default, the port rate mode for an expansion slot is mode0. To have the configuration take effect, you must save the configuration and restart the switch. For more information about the port-speed-mode command, see Ethernet interface commands in the command references for the switch.

To use a port on an expansion card as an IRF port, install an expansion card, and then configure IRF ports.

For more information about configuring basic IRF settings, see Virtual Technologies Configuration Guide in the configuration guides for the switch.

Connecting the physical IRF ports

Connect the IRF member switches as planned.

Wear an ESD wrist strap when you connect cables or transceiver modules and fibers. For how to connect them, see H3C Transceiver Modules and Network Cables Installation 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, web, or SNMP to access the IRF fabric from the network management station. (See Fundamentals Configuration Guide in the configuration guides for the switch.)

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.

Table4-2 Displaying and maintaining IRF configuration and running status

Task	Command
Display information about the IRF fabric.	display irf
Display all members’ IRF configurations that take effect at a reboot.	display irf configuration

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 Virtual Technologies in the configuration guides for the switch.
