LED Colors and Their Meanings

Listed below are the possible colors (and the corresponding meaning) of the LEDs on the HyperFabric adapters and switches.

Adapter LEDs

Table 5-1below shows the names of the LEDs on each HyperFabric adapter. Note that the LEDs on the A4920A adapter are labeled, but the labels might be hard to see when a cable is connected to the adapter.

Table 5-1	LED Names (by Adapter)
	LED Name	HyperFabric
		Adapter
	“Connected/Traffic”	A4919A
		A6092A
	“Link”	A4920A
		A6386A
	“Link	A4921A
	Connected/Traffic”
	“Error”	All

Some of the LEDs—“Connected/Traffic,” “Link,” and “Link Connected/Traffic”—are equivalent but are labeled differently, depending on the adapter. So, their colors and meanings are the same, regardless of the adapter.

The HyperFabric adapter LED colors and meanings are as follows:

✓If the adapter is not operational, the “Connected/Traffic,” “Link,” or “Link Connected/Traffic” LED on the adapter is off. Some of the possible reasons for this happening are the following:

—The HP 9000 is not operational.

—HyperFabric has not been started on the HP 9000.

—An adapter is installed in a slot in the HP 9000, but the cable is attached incorrectly or no cable is attached at all.

—The adapter is bad.

—The cable is bad.

—The switch port is bad (if the adapter is connected to a switch). Note that if a switch port is bad, and (for some reason) you cannot use a different port on the switch, you must replace (1) the entire HF1 switch, or (2) replace the switch module in the HF2 switch (whichever is applicable). However, you first should try turning the switch’s power off and then back on.
