The UltraTrak100 TX8 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). 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 8). 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 UltraTrak100 TX8 disk array that
detects the insertion or removal of a power supply.
Only trained and qualified personnel should remove the power supplies from the
UltraTrak100 TX8.
1. Switch the failed power supply Off.
2. Remove the power supply locking screw.
3. Using the pull handle on the power supply pull it from the chassis.
4. Insert the new power supply into the chassis and switch the power supply
power On.
5. Check that the Power LED indicator is illuminated.
6. Insert and tighten the power supply locking screw.
