The following sections define the power supply condition reports.
0.2.en.01 NONCRITICAL Condition—Power supply AC input m issing
The loss of the AC input to a power supply makes the remaining p ower 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. Ensure that there is AC power to the rack PDU, and 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 co rd 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 operat
ional power supply will automa tically shut down after seven m inutes, thereby disabling the
enclosure. This c ondition report remains active until either the problem is corrected, or the o perational
power supply shuts down, whichever occurs first.
To correc
t this p roblem, 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 resul
t if the power supply is removed before a replacement is available.
0.2.en.03 CRITICAL condition—Power supply loa d unba lanced
This condition report indicates that a component within a power s upply may have failed. This can make
the remaining power supply a single p oint of failure.
This c ondition report remains active until corrected.
Complete the following procedure to correct this problem:
1. Record all six characters of the condition report.
