POST-operation LED indications

The system status LEDs flash in various patterns during boot, POST, or other diagnostic tests. This
is normal and does not indicate a problem unless the LEDs do not indicate a healthy state after all
boot processes and diagnostic tests are complete.
During POST and some diagnostics, both system status LEDs—located at the top of the installed
switch module—operate simultaneously. The LED indications are described in

Brocade FCoE Switch Module for IBM BladeCenter: Installation and User Guide
If one or more LEDs do not display a healthy state, verify that the LEDs are not set to beacon.
Use the switchShow command or Web Tools to verify the LED state. For information about how
to turn beaconing on and off, refer to the Fabric OS Administrator's Guide or the Web Tools
Administrator's Guide.
Use the blade server chassis' Management Module to verify that the switch module is working
correctly.
Review the system log for errors.
Any errors detected during POST are written to the system log. This log is accessible through
the errShow command. For information about this command, refer to the Fabric OS Command
Reference. For information about error messages, refer to the Fabric OS Message Reference.
