Determining Whether a Switch is Faulty
If you suspect that a HyperFabric switch is faulty, follow the steps below
to determine if the switch needs replacing.
HF1 Switch
The steps for determining if an HF1 switch is faulty are as follows:
Step 1. Disconnect the cable from the switch port you suspect is faulty.
Step 2. Attach a copper loopback plug to the relevant port. A copper loopback
plug is shipped with each HF1 adapter (not with the HF1 switch).
Step 3. Determine if the port is faulty:
• If the port is functioning correctly, the port’s LED shows as solid or
blinking green.
• If the port is faulty, the port’s LED is off.
Repeat Steps 1 through 3 for all ports on the switch, to determine if any
of them are faulty.
Step 4. If any one of the ports on the switch is faulty, do not use it. Use a known
good port if one is available. If no good ports are available, you must
replace the switch. (See “Replacing a HyperFabric Switch” on page 177.)
HF2 Switch
The steps for determining if an HF2 switch is faulty are as follows:
Step 1. Check the cards/switch module in the switch—the integrated Ethernet
management LAN adapter card, integrated 8-port fiber card, and switch
module in the expansion slot:
a. If the card/switch module is functioning correctly, its
“Operating/Fault” LED shows as solid green.
b. If the card/switch module is experiencing a fault, its
“Operating/Fault” LED shows as solid yellow.
c. If the card/switch module is not operating, its “Operating/Fault” LED
is off.
