Determining Whether an Adapter or a Cable is Faulty

Determining Whether an Adapter or a Cable is
Faulty
If you suspect that either an HyperFabric adapter or a cable attached to
it is faulty, follow these steps to determine which component needs
replacing:
Step 1. Disconnect the cable from the HyperFabric adapter.
Step 2. Attach a loopback plug to the adapter:
• For the A4919A, A4920A, A4921A, and A6092A adapters: Be sure to
use a copper loopback plug (one is shipped with each HF1 adapter).
• For the A6386A adapter: Be sure to use a fiber loopback plug (one
[HP part number A6384-67004] is shipped with each HF2 switch).
Step 3. Determine if the adapter is faulty:
• If the adapter is functioning correctly, the “Connected/Traffic,”
“Link,” or “Link Connected/Traffic” LED on the adapter shows as
solid green.
• If the adapter is faulty, the “Error” LED on the adapter shows as
solid yellow.
See Table 6-1 on page 159 for a list of the LED names for each
HyperFabric adapter.
Step 4. If the adapter is faulty, you must replace it (see “Replacing a
HyperFabric Adapter” on page 176).
If the adapter is not faulty, assume that the cable is faulty and you must
replace it.
