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 c orrect this problem:
1. Record all six characters of the condition report.
2. Ensure that there is AC power to the rack PDU, and from the PDU to the PDMs and that the PDU and
PDM c ircuit breakers are not r eset.
If there is no AC power to the PDU, contact building facilities ma nag em ent.
Verify that the power supply AC power cord is properly connected.
3. If AC is present, and the rack power distribution circuitry is functioning properly, the power supply
indicator should be on.
4. Observe the EMU to ensure the error is corrected.
5. Contact your authorized service representative.
0.2.en.02
UNRECOVERABLE condition—Power supply missing
This condi
tion report indicates a power supply is not installed or installed incorrectly. Both of these
conditions affect air flow within the enclosure and can c ause an overtemperature condition. Enclosure
shutdown is imminent.
The opera
tional power supply will automatically shut down after seven minutes, thereby disabling the
enclosure. This c ondition report remains active until either the problem is corrected, or the op erational
power supply shuts down, whichever occurs first.
To correc
t this problem, record all six characters of the condition report, then contact your authorized
service representative.
CAUTION:
Removing power from an enclosure may cause the loss or corruption of data. To avoid this condition, shut
down the s
ystem using HP Command View EVA. An automatic shutdown and possible data corruption
may resu
lt if the power supply is removed before a replacement is available.
0.2.en.03 CRITICAL condition—Power supply load unbalanced
This condition report indicates that a component within a power supply may have failed. This can make
the remaining power supply a single point of failure.
This condition report remains active until corrected.
Complete the following procedure to c orrect this problem:
