Preparing for installation

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

• Before cleaning the switch, unplug 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 proper ventilation of the equipment room and keep the air inlet and outlet vents of the switch free of obstruction.

• Connect the yellow-green protection grounding cable before power-on.

• 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 interface cards, power modules, and fan trays, wear an ESD-preventive wrist strap to avoid damaging the units.

Examining the installation site The S5120-HI switches must be used indoors. You can mount your switch in a rack or on a workbench, but make sure:

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

• The rack or workbench has a good ventilation system.

• Identify the hot aisle and cold aisle at the installation site, and make sure ambient air flows into the switch from the cold aisle and exhausts to the hot aisle.

• Identify the airflow designs of neighboring devices, and prevent hot air flowing out of the bottom device from entering the top device.

• The rack is sturdy enough to support the switch and its accessories.

• The rack or workbench is well earthed.

To ensure proper 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 creepage, mechanical property change of materials, and metal corrosion.

7

• Lasting low relative humidity can cause washer contraction and ESD and bring problems including loose captive 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, see "Appendix A Technical specifications."

Cleanness Dust buildup on the chassis may 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.

Table 1 Dust concentration limit in the equipment room

Substance Concentration limit (particles/m³)

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

EMI All electromagnetic interference (EMI) sources, from outside or inside of the switch and application system, adversely affect the switch in a conduction pattern of capacitance coupling, inductance coupling, electromagnetic wave radiation, or common impedance (including the grounding system) coupling. To prevent EMI, take the following actions:

• 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.

• Route interface cables only indoors to prevent signal ports from getting damaged by overvoltage or overcurrent caused by lightning strikes.

Laser safety The S5120-HI switches are Class 1 laser devices.

Grounding the switch

WARNING!

Correctly connecting the switch grounding cable is 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 EMI susceptibility of the switch.

22

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

• Grounding the switch with a grounding strip

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

• Grounding the switch by using the AC power cord

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.

Connecting the rear grounding point to a grounding strip

IMPORTANT:

Orient the grounding cable as shown in Figure 29 so you can easily install or remove power modules.

To connect the rear grounding point to a grounding strip:

1. Remove the grounding screw from the rear panel of the switch chassis.

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

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

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

If the installation site has no grounding strips, but earth ground is available, hammer a 0.5 m (1.64 ft) or longer angle iron or steel tube into the earth ground to serve as a grounding conductor.

The dimensions of the angle iron must be at least 50 × 50 × 5 mm (1.97 × 1.97 × 0.20 in). The steel tube must be zinc-coated and its wall thickness must be at least 3.5 mm (0.14 in).

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

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

• The power cord is properly connected.

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

• The console cable is properly 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 S5120-HI Switch Series Configuration Guides and H3C S5120-HI Switch Series Command References.

Setting up an IRF fabric

You can use H3C IRF technology to connect and virtualize S5120-HI switches into a virtual switch called an "IRF fabric" for flattened network topology, and high availability, scalability, and manageability.

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."

See "Grounding the switch", "Installing a fan tray," "Installing a power module," and "Connecting the power cord."

4. Power on the switches. N/A

5. (Optional) Install an expansion interface card. See "Installing an interface card."

6. Configure basic IRF settings. See H3C S5120-HI Switch Series IRF Configuration Guide.

7. Connect the physical IRF ports.

Connect the physical IRF ports on the switches.

Select appropriate cables according to physical IRF port types.

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 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 for dispersed access.

NOTE:

An S5120-HI IRF fabric can have up to 9 switches. As your business grows, you can plug an S5120-HI switch into an 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, see H3CS5120-HI Switch 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 a unique member ID.

43

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 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.

NOTE:

• Figure 54 and Figure 55 show the topologies of an IRF fabric made up of three S5120-52SC-HI switchesthat use the SFP+ ports on the front panel for IRF connections.

• The IRF port connections in the two figures are for illustration only, and more connection methods are available.

For information about the physical ports available for IRF connections on the S5120-HI switches, see "Identifying physical IRF ports on the member switches."

Figure 55 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.

To set up IRF connection, you must use 10-Gigabit ports, including the two SFP+ ports on the front panel and the 10-Gigabit ports on the expansion interface card. For the available interface cards, see "Appendix B FRUs and compatibility matrixes."

Follow the binding restrictions and guidelines described in Table 6 when you identify the physical IRF ports on the member switches.

Table 6 Binding matrix for IRF ports

Switch model Requirements

S5120-28SC-HI

S5120-34C-HI The two SFP+ ports on the front panel and 10-Gigabit ports on the expansion interface card can be bound to any IRF port.

S5120-52SC-HI

• The SFP+ ports (numbered 51 and 52) on the front panel must be bound to different IRF ports. For example, if you bind SFP+ port 51 to IRF port 1, you must bind SFP+ port 52 to IRF port 2.

• If a two-port interface card is used, you can bind port 1 on the card and SFP+ port 51 into one aggregate IRF link, and port 2 on the card and SFP+ port 52 into the other aggregate IRF link.

• If a one-port interface card is used, you can bind the port on the card and SFP+ port 51 into one aggregate IRF link.

S5120-58C-HI

• The physical ports on one interface card must be bound to the same IRF ports into aggregate IRF links.

• The SFP+ port numbered 53 on the front panel and the physical ports on the interface card in SLOT 2 must be bound to the same IRF port.

• The SFP+ port numbered 54 on the front panel and the ports on the interface card in SLOT 1 must be bound to the same IRF port.

45

Planning the cabling scheme Select appropriate cables to connect physical IRF ports:

• Use XFP transceiver modules and fibers to connect XFP ports.

• Use SFP+ transceiver modules and fibers to connect SFP+ ports over a long distance, and use SFP+ cables over a short distance.

• Use CX4 cables to connect CX4 ports.

• Use category 6 or above twisted pair cables to connect 1/10GBase-T Ethernet ports.

If the IRF member switches are far away from one another, choose the XFP/SFP+ transceiver modules with optical fibers. If the IRF member switches are all in one equipment room, choose CX4/SFP+ cables or twisted pair cables.

The following subsections describe several H3C recommended IRF connection schemes, and 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 differentsides, you must measure the distance between them to select an appropriate cable.

Connecting the IRF member switches in one rack

You can connect the IRF member switches in one rack (see Figure 56) through CX4/SFP+ cables or twisted pair cables, and Figure 57 shows the IRF fabric topology.

Connecting the IRF member switches in different racks

You can install IRF member switches in different racks side by side. Figure 58 shows an example for connecting nine IRF member switches in different racks by using XFP/SFP+ transceiver modules and optical fibers. The topology is the same as Figure 57.

Figure 58 Connect the IRF member switches in different racks

Configuring basic IRF settings After you install the IRF member switches, power on the switches, and log in to each IRF member switch (see H3C S5120-HI Switch Series Fundamentals Configuration 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.

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

For more information about configuring basic IRF settings, see H3C S5120-HI Switch Series IRF Configuration Guide.

Connecting the physical IRF ports Use proper cables to connect the IRF member switches as planned.

NOTE:

Wear an ESD-preventive wrist strap when you connect CX4/SFP+ cables or XFP/SFP+ transceiver modules and fibers. For how to connect them, see H3C Pluggable SFP/SFP+/XFP Transceiver Modules Installation Guide and "Installing/removing a CX4/SFP+ cable".

48

Accessing the IRF fabric to verify the configuration 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 H3C S5120-HI Switch Series Fundamentals Configuration 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 in Table 7.

Table 7 Displaying and maintaining IRF configuration and running status

Task Command

Display information about the IRF fabric. display irf

Display all members’ configurations that take effect after switch reboots. display irf configuration

Display topology information about the IRF fabric. display irf topology

NOTE:

To avoid IP address collision and network problems, configure at least 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 H3C S5120-HI Switch Series IRF Configuration Guide.

49

Maintenance and troubleshooting

Power module failure Look at the PWR1 or PWR2 LED of the switch to identify a power module failure. For more information about the PWR1 and PWR2 LEDs on the front panel of the switch, see Table 14.

If the power module system is correctly operating, the power module status LEDs are steady green. If the LEDs behave in any other way, verify the following items:

• The switch power cord is properly 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 H3C for help.

To replace a hot swappable power module, see "Installing/removing a power module."

Fan failure

CAUTION:

For the S5120-28SC-HI and S5120-52SC-HI switches, you can replace the fan tray without powering offthe switch. To prevent overheating, replace the failed fan tray within 2 minutes.

You can look at the system status LED and the seven-segment LED of an S5120-HI switch to identify a fan failure. If both LEDs are behaving as described in Table 8, a fan failure occurs.

Table 8 LED behaviors that identify a fan failure

LED Mark State

System status LED SYS Steady red

Seven-segment LED Unit

The LED displays a flashing F character.

The S5120-34C-HI and S5120-58C-HI switches use fixed fan trays. If a fan failure occurs, promptly contact H3C for help.

The S5120-28SC-HI and S5120-52SC-HI switches use hot swappable fan trays. When the fan tray fails, use the display fan command to verify that the expected airflow direction is the same as the airflow direction of the fan tray. If not, use the fan prefer-direction command to modify the configuration.

If the problem still exists, the fan tray might have failed. You can replace the fan tray as described in "Installing/removing a fan tray."

50

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 properly 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

• Emulation—VT100

Appendix D Cooling system

The cooling system of an S5120-HI switch comprises the ventilation holes in the chassis, fan tray, and built-in fans of hot swappable power modules. To guarantee that this cooling system can effectively work, you must consider the site ventilation design when you plan the installation site for the switches.

IMPORTANT:

The chassis and the power modules use separate air aisles. Make sure both aisles are not blocked.

The fan trays available for the S5120-28SC-HI and S5120-52SC-HI switches include LSPM1FAN and LSPM1FANB.

• When an LSPM1FAN fan tray is used, cool air flows in through the air vents in the fan tray panel, circulates through the chassis and the power modules, and exhausts at the network port side.

• When an LSPM1FANB fan tray is used, cool air flows in through the air vents in the network port-side panel, circulates through the chassis and the power modules, and exhausts through the air vents in the fan tray panel.

The S5120-34C-HI and S5120-58C-HI switches use fixed fan trays and left to right air aisles. Cool air flows in through the air vents in the left side (relative to the front panel) of the chassis, circulates through the chassis and the power modules, and exhausts at the air vents in the right side of the chassis and built-in fan outlet of power modules.
