Replacing a Power Supply 59
NOTE: When locating the failed power supply, the “DC Good” LED will be OFF.
2Using a flat-blade screwdriver, loosen the rear door access screw. Open the
door to gain access to power supplies #1 and #2.
If you are replacing the #3 power supply, loosen the two PSU Cover Plate
screws. Remove the cover plate and skip to step 3.
3Grasp the handle of the subject power supply and pull the supply out of the
CR8e enclosure.
NOTE: The orientation of the power supply being removed. This will facilitate
the installation of the replacement supply.
4Remove the new power supply from the shipping carton and inspect the
shipment. Save the packaging material.
5Slide the new power supply into the cabinet until it reaches its locked
position.
NOTE: Orient the power supply in the same manner as the removed power
supply. (Air slots in the PSU case face toward the center of the cabinet.)
The new power supply’s LED should illuminate.
6Close the rear door panel. The door has a latch mechanism that holds the
door in the open position. Squeeze the latch to release the door allowing it to
be closed.
If you are replacing the #3 power supply, re-install the PSU Cover Plate and
then re-secure the power cord retainer.
7Using the packaging materials from the replacement power supply, repackage
and return it to nStor Corporation, refer to the nStor Resource Guide for
information on “Obtaining a Return Material Authorization.”
