ers are summed to drive the front panel LEDs.

base station.
Power LED The green power LED is lit when power is supplied to the subrack.
Alarm LED The red alarm LED will flash at a rate of 2 to 5 Hz when an alarm has been
generated by any of the base station modules. It will continue to flash until
the alarm is canceled or the fault is fixed. Note that only those alarms which
are enabled using the web interface will cause this LED to flash.
