Warning
Only qualified service personnel should remove and replace a power
supply module.
Replacing a Power Supply Module (
–8000 series only
)
The UltraTrak SX8000 and RM8000 disk array contains two hot-swappable
redundant power supplies. Normally, these supplies share the load between
them. However each power supply is capable of providing the power needed to
maintain the array’s normal operation. Each power supply LED should be on. An
off or blinking LED on the power supply indicates that the power supply has failed
and should be replaced. A power supply failure is also accompanied by an
audible alarm.
Note
Press the Power Supply Alarm Reset button to turn off the alarm. See
Figure 15.
Contact your dealer or reseller for additional details and assistance in obtaining a
replacement supply.
These power supplies are accessible from the rear of the unit (see Figure 15 on
the next page). The power supply may be removed and replaced with an identical
power supply while the array remains in operation. To protect the electronic
circuits, special sensing circuitry is incorporated into the design of the UltraTrak
8000 series disk array that detects the insertion or removal of a power supply.
