Table 2-1 describes the possible display states of these LEDs during operation.
Fan Status LEDs
The SRM provides a set of Fan Status LEDs for each of the fan arrays installed in
the BSR 64000 chassis. These LEDs are visible on the module front panel of the
SRM and are labeled: OK and Fail. Table 2-2 describes the possible display states
of the LEDs.

Fail Status Alarm Interpretation
Off Green Off Normal operating status.
Off Green Red Failure. SRM is operating with an alarm
condition.
Red Off Off Indicates a module hardware failure.
The LED is red when the BSR is receiving
power, but there is no power to the circuitry. This
can occur if a fuse on a BSR 64000 module is
down.
A red LED can also occur if the BSR 64000 does
not boot correctly.
Red Off Red Failure. SRM is not operational.
Red Green Red Reset. SRM is booting.
Off Off Off If the Status LED is off and the Fail LED is off,
there is no power. The power source for the BSR
64000 has failed.
• Check the -48V DC power source(s) for
power to the BSR 64000. The -48V DC
power source may be faulty.
Check the UPS for the BSR 1000.
