Interpreting LED Activity

SAN Switch 2/8 activity and status can be determined through the activity of the LEDs on the switch. The LEDs will flash green, yellow, or orange while the switch is booting and while POST or other diagnostic tests are running. This is normal and does not indicate a problem.

Note: Any errors related to LED activity are listed in the error log. For information about the error log, refer to the hp StorageWorks Fabric OS V3.0.x/V4.0.x Procedures Guide.

Front Panel LEDs

One power switch LED on the front panel

One port status LED above and to the left of each of the 8 ports

One port speed LED above and to the right of each of the 8 ports Table 4 describes how front panel LEDs communicate switch status.
