Installing/removing a fan tray CAUTION: To ensure good ventilation for the switch: • Install two fan trays of the same model on the switch. • Do not power on the switch when no or only one fan tray is installed.
Select fan trays as required. For the available fan trays and their specifications, see "Fan trays." To install a fan tray: 1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded. 2. Unpack the fan tray and verify that the fan tray model is correct. 3.
1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded. 2. Loosen the captive screw of the fan tray with a Phillips screwdriver until it is fully disengaged from the switch chassis. 3. Grasp the handle of the fan tray with one hand and pull the fan tray part way out the slot. Support the fan tray bottom with the other hand, and pull the fan tray slowly along the guide rails out of the slot. 4. Put away the removed fan tray in an antistatic bag for future use.
Installing a power supply CAUTION: • Follow the forward inertia of the power supply when inserting it into the chassis, and make sure the power supply has firm contact with the connectors on the backplane. • To prevent damage to the connectors inside the switch chassis, insert the power supply gently. If you encounter a hard resistance while inserting the power supply, pull out the power supply and insert it again.
Figure 20 Installing a filler module Removing a power supply CAUTION: If the switch has two power supplies, removing one power supply does not affect the operation of the switch. If the switch has only one power supply, removing the power supply powers off the switch. To remove a 650W AC or 650W DC power supply from the switch: 1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded. 2.

versions. For more information about Boot ROM menu options, see the release notes for the switch software. After the startup completes, you can access the CLI to configure the switch. For more information about the configuration commands and CLI, see HP 5920 & 5900 Switch Series Configuration Guide and HP 5920 & 5900 Switch Series Command References.
Setting up an IRF fabric You can use HP 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. To set up IRF links between the switches, use SFP+ ports, 1/10-GE Ethernet ports, or QSFP+ ports.
Step Description Plan the installation site and IRF fabric setup parameters: 1. Plan IRF fabric setup. • • • • • 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 ground wires and power cords.
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 HP 5920 & 5900 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.
Figure 29 IRF fabric in ring topology 1 2 3 IRF-port1 IRF-port2 1 IRF-port2 IRF-port1 IRF-port1 IRF-port2 2 3 Identifying physical IRF ports on the member switches Identify the SFP+ or QSFP+ ports to be used for IRF connections on the member switches according to your topology and connection scheme.
• On the HP 5900AF-48G-4XG-2QSFP+ and 5900AF-48G-4XG-2QSFP+ TAA switches, SFP+ ports numbered 49, 50, 51, and 52 form one group. • On the HP 5900AF-48XGT-4QSFP+ and HP 5900AF-48XGT-4QSFP+ TAA switches, the 1/10-GE ports are grouped by port number in ascending order, starting from one. Every four 1/10-GE ports form one group.
Figure 30 Connecting the switches in one rack 1 2 3 4 Figure 31 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 32 shows an example for connecting four top of rack IRF member switches by using SFP+/QSFP+ DAC cables, and SFP+/QSFP+ transceiver modules, and optical fibers. The topology is the same as Figure 31.
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. For more information, see HP 5920 & 5900 Switch Series Fundamentals Configuration Guide. 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.
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 HP 5920 & 5900 Switch Series IRF Configuration Guide.
Maintenance and troubleshooting Power supply failure You can use the LEDs on the power supply to identify a power supply failure. For more information about the LEDs on a power supply, see HP A58x0AF 650W AC (JC680A) & 650W DC (JC681A) Power Supplies User Guide. If the LEDs on the power supply are not steady green (active) or blinking green (standby), the power supply is faulty. To resolve the problem: 1. Verify that the power cord is connected securely. 2.
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 problem persists, contact HP support.
