Troubleshooting HyperFabric

Determining Whether a Switch is Faulty

a.If the port is connected to an operational Ethernet network, the port’s LED

(“Ethernet Port Main” or “Ethernet Port Aux”) shows as solid or blinking green.

b.If the port is disconnected, or connected to an Ethernet network that is not operational, the port’s LED is off.

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

•If the port is on the A6389A HF2 4-port copper switch module in the expansion slot, use a copper loopback plug (one is shipped with each HF1 adapter).

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 fibre card can be removed by qualified Hewlett-Packard personnel only. The A6388A and A6389A switch modules can be removed by you or qualified Hewlett-Packard personnel.

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