Features
Only one operational power supply and one operational blower are required to keep the enclosure fully
functional. However, in the event of a component failure, HP strongly recommends that a replacement is
installed as soon as possible.
NOTE:
When a power supply fails, the associated blower is disabled.
The power supply circuitry monitors input voltage, current, and temperature. If it detects an unacceptable
level of any of these elements, the status indicator turns off and an error is reported to the EMU.
The EMU uses the temperature sensor signal to adjust the speed of the blowers. If one blower fails or
spins at a reduced speed, the speed of the other blower increases to provide adequate air
fl
ow.
Power supply and blower status indicator
A green LED on the blower (
Figure 6
-2) indicates the operational status of the power supply and the
blower. If either component fails, the LED turns off and an error alarm sounds. The failing component
should be replaced as soon as possible.
Fibre Channel disks
Up to 14 HP FC disk drives can be installed in a DS2500. Only HP-supplied FC disk drives are supported
in a DS2500.
Figure 7
shows an FC disk drive.
