The following sections define the power supply condition reports.
0.2.en.01 NONCRITICAL Condition—Power Supply AC Input Missing
The loss of the AC input to a power supply makes the remaining power supply a single point of failure.
This condition report remains active until AC power is applied to the power supply.
Complete the following procedure to correct this problem:
1. Record all six characters of the condition report.
2. Ensu re that there is AC power to the rack PDU, a nd from the PDU to the PDMs and that the PDU and
PDM circuit breakers are not reset.
If there is no AC power to the PDU, contact building facilities management.
Verify that the power supply AC power c ord is properly connected.
3. If AC is present, and the rack power distribution circuitry is functioning properly, the power supply
LED s hould be on.
4. O bserve the EMU to ensure the error is corrected.
5. Contact your authorized service representative.
0.2.en.02 U NRECOVERABLE Condition—Power Supply Missing
This condition report indicates a power supply is not installed or installed incorrectly. Both of these
conditions affect air flow within the enclosure and can cause an overtemperature condition. Enclosure
shutdown is imminent.
The o perational power supply will automatically shut down after seven minutes, thereby disabling the
enclosure. This condition report remains active until either the problem is corrected, or the operational
power supply shuts down, whichever occurs first .
To correct this problem, record all six characters of the condition report, then contact your authorized
service representativ e.
CAUTION:
Removing power from an enclosure may cause the loss or corruption of data. To avoid this condition,
shut down the system using Command View EVA. An automatic shutdown and possible data corruption
may result if the power supply is removed before a replacement is available.
