Figure 66: Blower element numbering
Caution: A single blower 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 blower is operating 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 blower as soon as possible.
To correct this problem, record all six characters of the condition report, then
contact your HP authorized service representative.
