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 6-1 below 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.
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 the switch module in the HF2 switch. However, you
first should try turning the switch’s power off and then back on.
— The adapter is connected to a non-operational adapter in the remote node (in a
node-to-node configuration).
