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 fibre 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 5-1 on page 111 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 125).

If the adapter is not faulty, assume that the cable is faulty and you must replace it.
