CAUTION:
A single
operating at high speed can provide sufficient air flow to cool an enclosure and the
elements for up to 100 hours. However, operating an enclosure at temperatures approaching an
overheating threshold can damage elements and may reduce the MTBF of a specific element. Immediate
replacement of the defective blower is required.
The following sections define the power supply condition reports.
0.3.en.01 NONCRITICAL condition—Blower speed
A
is operating at a speed outside of the EMU specified range, possibly because of a bearing
problem. This can affect enclosure cooling and cause an element to fail. This condition report remains
active until the problem is corrected.
This error does not normally require immediate correction. However, an error of this type could contribute
to an element overheating.
HP recommends replacing the
as soon as possible.
To correct this problem, record all six characters of the condition report, then contact your HP authorized
service representative.
0.3.en.02 CRITICAL condition—Blower speed
A
is operating at a speed that is significantly outside the EMU specified range, possibly because
of a bearing problem. This can cause the loss of cooling and cause an element to fail. The error remains
active until the problem is corrected.
HP recommends replacing the
as soon as possible.
To correct this problem, record all six characters of the condition report, then contact your authorized
service representative.
