Power Supply

This section describes how to remove and replace the power supply in the J5000 and J7000
workstations. As you face the workstation, the power supply is on the right side.
NOTE
If the LCD displays an error message that relates to one of the power supply's
internal cooling fans, you will need to replace the entire power supply. Follow
the removal and replacement procedures in this section to do so.
Removing the Power Supply
To remove the power supply, do the following:
1. Remove the top panel and the right side panel of the workstation.
2. Remove the PCI retainer clip, which is located below the power supply.
3. Remove the bus bar shield above the power supply.
4. Remove the four bus bar thumbscrews on the J5000 workstation, or the five bus bar
thumbscrews on the J7000.
5. Remove the two T-15 Torx screws that secure the power supply to the rear panel of the
workstation. The screws are located at the top and lower outer edges of the power
supply on the rear panel.
6. As you face the power supply on the right side of the workstation, remove the T-15 Torx
screw in the lower-left corner of the power supply.
7. Alternately unscrew the two jack screws on the power supply to break the seating in the
I/O board connectors.
The power supply weighs approximately 17 pounds, so you should be
CAUTION
prepared to handle the weight accordingly in the next step.
8. Use both hands to firmly pull the power supply out of the I/O board connectors.
Replacing the Power Supply
To replace the power supply, do the following:
1. Remove the top panel and the right side panel of the workstation.
2. Inspect the underside of the gold plated bus bars for missing or damaged conductive
interface material. The conductive interface material provides a biting function when
the bus bars are properly tightened down.
3. Inspect to ensure that the SCSI cable from the SCA hard disk interface (backplane
board) to the I/O board does not interfere with the power supply's guide rails.
4. Pick up the power supply with both hands and align the power supply with the guide
rails. Slide the power supply forward on the guide rails to seat it in the I/O board
connectors.
