EMU Status

Single Blower Fault

Operational blowers are running at high speed.

Missing Blower Fault or Multiple Blower
Faults

Operational blowers are running at high speed.

Probable Cause 1—A blower is removed.

Replace the missing blowers.

Probable Cause 2—All blowers in one bank
are not operating. Remove and install blowers
correctly within 8 minutes.

Probable Cause 3—Multiple blowers are
installed incorrectly.

Remove and install blowers correctly within 8
minutes.

Comment—In this example, one of the
following conditions exist in shelf bank 1:

•

A blower is removed.

•

Two or more blowers are not operating.

Failure to replace the missing or defective
blowers within 8 minutes might result in the
enclosure entering standby power mode.
