Troubleshooting HyperFabric

LED Colors and Their Meanings

❏For each port on the cards/switch module in the switch:

✓If the port is not operational, the LED is off. Some of the possible reasons for this happening are the following:

—A cable is not attached correctly to the port or no cable is attached at all.

—The port is connected to a non-operational adapter in an HP 9000. (See “Adapter LEDs” on page 143 or Table 6-2 on page 145 for some tips about a non-operational adapter.)

—The cable is bad.

—The port is bad. Note that if a port is bad, and (for some reason) you cannot use a different port on that card/switch module, you can replace the card/switch module. Remember, though, that the integrated 8-port fiber card can be removed by qualified HP personnel only. The A6388A and A6389A switch modules can be removed by you or qualified HP personnel. However, you first should try turning the switch’s power off and then back on.

✓If the connection from the port to the corresponding adapter in the HP 9000 is operational, the LED on the port shows as solid green.

✓If data is flowing between the port and the corresponding adapter, the LED shows as flashing green. Note that data does not start to flow until HyperFabric initialization has occurred (see “Using the clic_init Command” on page 79).

Note that a legend listing the possible port states—disconnected, connected, and traffic—and the corresponding LED colors is printed on the front of the switch, for your reference. See Figure 3-2 on page 59 and Figure 3-3 on page 60, for the locations of the switch LEDs and the legend.

Table 6-3 below summarizes the HF2 switch LED information in a table format.
