Troubleshooting HyperFabric

Determining Whether a Switch is Faulty

Chapter 6 155

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

” LED shows as

solid or blinking green.

• If the port is faulty, the “Port

” 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.
