Troubleshooting HyperFabric

Determining Whether a Switch is Faulty

Step 4. Check the ports on the cards/switch module:

a.Disconnect the cable from the card/switch module port you suspect is faulty.

b.Attach a loopback plug to the relevant port:

•If the port is on the integrated 8-port fiber card or the A6388A HF2 8-port fiber switch module in the expansion slot, use a fiber loopback plug. (A fiber loopback plug [HP part number A6384-67004] is shipped with each HF2 switch).

c.Determine if the port is faulty:

•If the port is functioning correctly, the “Port x” LED shows as solid or blinking green.

•If the port is faulty, the “Port x” LED is off.

Repeat steps a through c for each port on the cards/switch module, to determine if any of them are faulty.

d.If the port is faulty, do not use it. Instead, use a known good port on that card/switch module if one is available. If no good ports are available, replace that card/switch module. Remember, though, that the integrated 8-port fiber card can be removed by qualified HP personnel only. The A6388A and A6389A switch modules can be removed by you or a qualified HP personnel.

Step 5. If a fan is not running, the fan tray must be replaced by qualified HP personnel only.
