To avoid any 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, unplugall power cordsfromthe 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 goodventilation of the equipment room and keep the air inlet and outlet vents of the switch free of obstruction.

· Make sure the operating voltage is in the required range.

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

· When replacing FRUs,including power modules and fan trays, wear an ESDwrist strap to avoid damaging the units.

Examining the installation site

The switch must be used indoors.

Mount your switch in a rack and make sure:

· Adequate clearance is reserved at the air inlet and exhaust vents for ventilation.

· The rack has a good ventilation system.

· Identify the hot aisle and cold aisle at the installation site, and make sureambient air flows into the switch from the cold aisle and exhausts to the hot aisle.

· Identify the airflow designs of neighboring devices, and prevent hotair flowing out of the bottom device from entering thetop device.

· The rack is sturdy enough to support the switchand its accessories.

· The rack is correctly grounded.

To ensure normal operation and long service life of your switch, install it in an environment that meets the requirements described in the following subsections.

Temperature/humidity

Maintain appropriate temperature and humidity in the equipment room.

· 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 bring problems including loose mountingscrews 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 different switch models, see"Technical specifications."

Cleanliness

Dust buildup on the chassis might result in electrostatic adsorption, which causes poor contact of metal components and contact points, especially when indoor relative humidity is low. In the worst case, electrostatic adsorption can cause communication failure.

Dust

≤ 3 x 104 (no visible dust on the tabletop over three days)

NOTE:

Dust diameter ≥ 5 μm

The equipment room must also meet limits on salts, acids, and sulfides to eliminate corrosion and premature aging of components, as shown in Table 2.

Table 2 Harmful gas limits in the equipment room

Gas	Maximum concentration (mg/m3)
SO2	0.2
H2S	0.006
NH3	0.05
Cl2	0.01

EMI

Electromagnetic interference (EMI) might be coupled from the source to the switch through the following coupling mechanisms:

· Capacitive coupling

· Inductive coupling

· Radiative coupling

· Common impedance coupling

· Conductive coupling

To prevent EMI, usethe following guidelines:

· 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 switch far away from radio transmitting stations, radar stations, and high-frequency devices.

· Use electromagnetic shielding, for example, shielded interface cables, when necessary.

· To prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightning strikes, route interface cables only indoors.

Laser safety

WARNING!

Do not stare into any fiber port when the switch has power. The laser light emitted from the optical fiber might hurt your eyes.

The switch is aClass 1 laser device.

Installation tools

The installation tools are not provided with the switch. Prepare them yourself.

· Phillips screwdriver

· ESD wrist strap

(5) Front mounting position

Attaching the mounting brackets and chassis rails to the chassis

1. Align the mounting brackets with the screw holes in the rear mounting position (see Figure 7) or front mounting position (seeFigure 8).

2. Use M4 screws (supplied with the switch) to attach the mounting brackets to the chassis.

3. Align the chassis rails with the rail mounting holes in the chassis:

¡ If the mounting brackets are in the rear mounting position, align the chassis rails with the screw holes at the front of the side panels (see Figure 7).

¡ If the mounting brackets are in the front mounting position, align the chassis rails with the screw holes at the rear of the side panels (seeFigure 8).

4. Use M4 screws (supplied with the switch) to attach the chassis rails to the chassis.

NOTE:

Secure the mounting brackets and chassis rails to both sides of the chassis in the same way.

Connecting the grounding cable to the chassis

CAUTION:

The primary grounding point and auxiliary grounding point 1 are located on the left side panel. If you use one of these grounding points, you must connect the grounding cable to the grounding point before youmountthe switch inthe rack.

Toconnect the grounding cable toa chassis grounding point, for example, the primary grounding point:

1. Choose a grounding point.

2. Unpack the grounding cable and grounding screws.

3. Align the two-hole grounding lug at one end of the cable with the grounding holes of the grounding point, insert the grounding screws into the holes, and tighten the screws with a screwdriver to attach the grounding lug to the chassis, as shown in Figure 7.

Figure 7 Attachingthe rear mounting brackets/chassis rails/grounding cable to the chassis

Figure 8 Attachingthe front mounting brackets/chassis rails to the chassis

NOTE:

As a best practice,use the primary grounding point or auxiliary grounding point 1 because the grounding cable and grounding screw that come with the switch are suitable only forthese two grounding points.

Attaching the slide rails to the rack

1. Identify the rack attachment position for the slide rails, and mark cage nut installation positions on the rack posts.

2. Install cage nuts(user-supplied)in the mounting holes in the rack posts.

3. Align the screw holes inone slide rail with the cage nuts in the rack post on one side, and use screws (user supplied) to attach the slide rail to the rack, as shown in Figure 9.

4. Repeat the preceding step to attach the other slide rail to the rack post on the other side.

Keep the two slide rails at the same height so the slide rails can attachinto the chassis rails.

Figure 9 Installing the slide rails

Mounting the switch in the rack

This task requires two people.

To mount the switch in the rack:

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

2. Verifythat the mounting brackets and chassis rails have been securely attached to the switch chassis.

3. Verifythat the slide rails have been correctly attached to the rear rack posts.

4. Install cage nuts (user-supplied)to the front rack posts and make sure they are at the same levelas the slide rails.

5. Supporting the bottom of the switch, align the chassis rails with the slide rails on the rack posts, as shown inFigure 10.Work with another person to slide the chassis rails along the slide rails until the mounting brackets are flush with the rack posts.

6. Use screws (user-supplied) to attach the mounting brackets to the rack, as shown in Figure 11.

To secure the switch in the rack, make sure the front ends of the slide rails reach out of the chassis rails.

Figure 10 Mounting the switch in the rack (1)

Figure 11 Mounting the switch in the rack (2)

Grounding the switch

WARNING!

Correctly connecting the switch grounding cableis crucial to lightning protection and EMI protection.

The power input end of the switch has a noise filter, whose central ground is directly connected to the chassis to form the chassis ground (commonly known as PGND).You must securely connect this chassis ground to the earth so the faradism and leakage electricity can be safely released to the earth to minimize EMIsusceptibility of the switch.

You can ground a switch by using a grounding strip at the installation site or the AC power cord connected to the switch.

NOTE:

The power and grounding terminals in this section are for illustration only.

Grounding the switch with 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, connect the grounding cable to the grounding strip.

To connect the grounding cable:

1. Attach the two-hole grounding lug at one end of the grounding cable to a grounding point onthe switchchassis (see "Connecting the grounding cable to the chassis").

2. Remove the hex nut ofa grounding post on the grounding strip.

3. Attach the ringterminal at the other end of thegrounding cable to the grounding strip through thegrounding post, and fasten the ringterminalwiththe removedhex nut.

Figure 12 Connecting the grounding cable to a grounding strip

(1) Hex nut	(2) Ringterminal
(3) Grounding post	(4) Grounding strip

NOTE:

· As a best practice,use the primary grounding point or auxiliary grounding point 1, because the grounding cable and grounding screw provided with the switch are applicable only to these two grounding points.

· To useauxiliary grounding point 2 on the switch, prepare a grounding cable yourself.The connection method is the same as connecting to the other two grounding points.

Grounding the switch by using the AC power cord

If the installation site has no grounding strips, you can ground an AC-powered switch through the protective earth (PE) wire of the power cord, but must make sure:

· The power cordhas a PE terminal.

· The ground contact in the power outlet is securely connected to the ground in the power distribution room or on the AC transformer side.

· The power cord is securely connected to the power outlet.

NOTE:

If the ground contact in the power outlet is not connected to the ground, report the problem and reconstruct the grounding system.

Figure 13 Grounding through the PE wire of the AC power cord

Accessing the switch for the first time

Setting up the configuration environment

The first time you access the switch you must use a console cable to connect a console terminal, for example, a PC, to the console port on the switch.

Figure 23 Connecting the console port to a terminal

Connecting the console cable

Console cable

A console cable is an 8-core shielded cable, with a crimped RJ-45 connector at one end for connecting to the 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.

Figure 24 Console cable

Connection procedure

To connect a terminal (for example, a PC) to the switch:

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

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

NOTE:

· Identify the mark on the console port and make sure you are connecting to the correct port.

· The serial ports on PCs do not support hot swapping. If the switch has been powered on, connect the console cable to the PC before connecting to the switch, and when you disconnect the cable, first disconnectfrom the switch.

Setting terminal parameters

To configure and manage the switch, you must run a terminal emulator program on the console terminal.

The following are the required terminal settings:

· Bits per second—9,600

· Data bits—8

· Parity—None

· Stop bits—1

· Flow control—None

· Emulation—VT100

To set terminal parameters, for example, on a Windows XP HyperTerminal:

1. Select Start>All Programs>Accessories>Communications>HyperTerminal.

The Connection Descriptiondialog box appears.

2. Enter the name of the new connection in the Namefield and click OK.

Powering on the switch

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

· The power cord iscorrectly 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.

Power 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 H3C S6300 Switch Series Configuration Guides and H3C S6300 Switch Series Command References.

Setting up an IRF fabric

You can use H3CIRF technology to connect and virtualize S6300 switches into a large virtual switch called an "IRF fabric" for flattened network topology, and high availability, scalability, and manageability.

IRF fabric setup flowchart

Figure 30 IRF fabric setup flowchart

Toset 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."
3. Connect the groundingcable 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 H3C S6300 Switch Series IRF Configuration Guide.
6. Connect the physical IRF ports.	See "Planning IRF topology and connections." 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 rackfor centralized high-density access.

· Distributethe IRF member switches in different racks to implement the top-of-rack (ToR) access solution for a data center.

As your business grows, you can plug H3C S6300 switches into the IRF fabric to increase the switching capacity without any topology change or replacement.

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 command line interface of the master switch.

NOTE:

IRF member switches will 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, seeH3C S6300Switch Series IRF Configuration Guide.

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 aunique member ID.

Planning IRF topology and connections

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

You connect the IRF member switches through IRF ports, the logical interfaces for the connectionsbetween IRF member switches. Each IRF member switch has two IRF ports: IRF-port 1andIRF-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 1on one switch to the physical ports of IRF-port 2 on the other switch.

The S6300-42QF and S6300-52QFswitchescan provide 10-GE and 40-GE IRF connections through SFP+ ports and QSFP+ ports, respectively.

The S6300-42QTswitch can provide 10-GE and 40-GE IRF connections through 1/10-GE Ethernet ports, SFP+ ports, or QSFP+ ports.

The S6300-48S switch can provide 10-GE IRF connections through SFP+ ports.

You can bind severalports of the same type to an IRF port for increased bandwidth and availability.

Figure 31 and Figure 32 show the topologies of an IRF fabric made up of three S6300 switches.The IRF port connections in the two figures are for illustration only, and more connection methods are available.

Figure 31 IRF fabric in daisy chain topology

Figure 32 IRF fabric in ring topology

Identifying physical IRF ports on the member switches

Identify the ports to be used for IRF connections on the member switches according to your topology and connection scheme.

All ports on the front panel of the S6300 switch can be used for IRF connections.

Follow these guidelines when you identify 1/10-GE Ethernet ports and SFP+ports to be used for IRF connections:

· On anS6300-42QF, S6300-52QF, or S6300-48S switch, the SFP+ports are grouped by port number in ascending order, starting from one. Every four SFP+ports form one group.

· On an S6300-42QT switch, the 1/10-GE Ethernet ports and SFP+ ports are grouped by port number in ascending order, starting from 1 for 1/10-GE Ethernet ports and 33 for SFP+ ports, respectively. Every four ports form one group.

· Aport can be bound to an IRF port or operate as a service port. When aport is bound to an IRF port, other ports in the same port group cannot be used as service ports, and vice versa.

A common practice is to use one 1/10-GE Ethernet port/SFP+port group for IRF connections, and bind every two ports in the group to an IRF port for increased bandwidth and availability.

Planning the cabling scheme

Follow these guidelineswhen you use cables to connect switches:

· S6300-42QF/S6300-52QF switches—Use SFP+/QSFP+ cables or SFP+/QSFP+transceiver modules and fibers.

· S6300-42QT switches—Use category-6A or above twisted pair cables, SFP+/QSFP+ cables, or SFP+/QSFP+transceiver modules and fibers.

· S6300-48S switches—Use SFP+ cables or SFP+ transceiver modules and fibers.

If the IRF member switches are far away from one another, choose the SFP+/QSFP+transceiver modules with optical fibers. If the IRF member switches are all in one equipment room, choose category-6A or above twisted pair/SFP+/QSFP+ cables. For more information about available SFP+/QSFP+ cables and transceiver modules, see "SFP+ port" and "QSFP+ port."

The following subsections describe several H3C recommended IRF connection schemes, and all these schemes use a ring topology.

Connecting the IRF member switches inone rack

Use short-haul and long-haul SFP+ cables to connect the IRF member switches (fourswitches in this example) in a rack as shown inFigure 33. The switches in the ring topology (see Figure 34) are in the same order as connected in the rack.

Figure 33 Connecting the switches in one rack

Figure 34 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.

Figure 35 shows an example for connecting fourtop of rack IRF member switches by using SFP+/QSFP+cables, and SFP+/QSFP+ transceiver modules, and optical fibers. The topology is the same as Figure 34.

Figure 35 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 (seeH3C S6300 Switch Series FundamentalsConfiguration Guide) 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.

· Tobind the ports on an interface card to an IRF port, you must install the interface card first. For how to install an interface card, seeH3C S6300 Switch Series Interface Cards User Guide.

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

For more information about configuringbasic IRF settings, seeH3C S6300 Switch Series IRF Configuration Guide.

Connecting the physical IRF ports

Use category-6A or above twisted pair/SFP+/QSFP+ cables or SFP+/QSFP+transceiver modules and fibers to connect the IRF member switchesas planned.

NOTE:

Wear an ESD wrist strap when you connect SFP+ cables or SFP+ transceiver modules and fibers. For more information, seeH3C SFP/SFP+/XFP/SFP28 Transceiver Modules and Cables Installation Guide and H3C QSFP+/QSFP28 Transceiver Modules and Cables Installation Guide.

Accessing the IRF fabric to verify the configuration

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

1. Log in to the IRF fabricthrough 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 H3C S6300Switch Series FundamentalsConfiguration Guide.)

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 inTable 4.

Maintenance and troubleshooting

Power modulefailure

You can use the LEDs on the power module to identify a power module failure. For more information about the LEDs on a power module, seeH3C LSVM1AC300 & LSVM1DC300Power ModulesUser ManualandH3C LSVM1AC650 & LSVM1DC650Power ModulesUser Manual.

The LEDs on the power module are steady green (active) or flashing green (standby) while the power module system is correctly operating. If the LEDs behave in any other way, verify the following items:

· The switch power cord is correctly connected.

· The power source meets the requirement.

· The operating temperature of the switch is in the normal range and the power module has good ventilation.

If the problem persists, contact the H3C technical support for help.

To replace a power module, see "Installing/removinga power module."

Fantray failure

CAUTION:

· Install two fan trays of the same model on the switch.

· Do not operate the system with one failed fan tray for more than 24 hours.

· Do not remove the failed fan tray until you are ready for replacing it.

· Do not operate the system without any fan tray for more than 2 minutes.

· Do not operate the system outside of the temperature range 0°C to 45°C (32°F to 113°F) degrees.

When a fan tray has problems, the system status LED is steady red and the system outputs alarm messages.

To replace a failed fan tray, see "Installing/removing a fan tray."

Configuration terminal problems

If the configuration environment setup is correct, the configuration terminal displays booting information when the switch is powered on. If the setup is incorrect, the configuration terminal displays nothing or garbled text.

No terminal display

If the configuration terminal displays nothing when the switch is powered on, verify the following items:

· The power module is supplying power to the switch.

· The console cable is correctly connected.

· The console cable has no problem and the terminal settings are correct.

Garbled terminal display

If terminal display is garbled, verify that the following settings are configured for the terminal, for example, HyperTerminal:

· Baud rate—9,600

· Data bits—8

· Parity—none

· Stop bits—1

· Flow control—none

Appendix D Cooling system

The cooling system of the switchuses front-back ventilation. To guarantee that this cooling system can effectively work, you must consider thesite ventilation design when you plan the installation site for the switches.

Table 20 Switch fan tray ventilation description

Switch model	Fan tray	Air flow direction
· S6300-42QF · S6300-48S · S6300-52QF	LSWM1FANSC	Air flows in through the power module side and exhausts at the network port side
· S6300-42QF · S6300-48S · S6300-52QF	LSWM1FANSCB	Air flows in through the network port side and exhausts at the powermodule side
S6300-42QT	LSWM1HFANSC	Air flows in through the power module side and exhausts at the network port side
S6300-42QT	LSWM1HFANSCB	Air flows in through the network port side and exhausts at the powermodule side

NOTE:

To ensure correct ventilation, fan trays on the switch must have the same air flow direction.
