Replacing The Dc Power Harness - Sun Microsystems SPARCstation 5 Service Manual

13. Disconnect the DC power harness from the power supply and carefully remove
the harness from the system chassis.

Replacing the DC Power Harness

Visual markers have been placed on the internal cables to help you route the cables
through the metal cable clips properly. The markers are either tie-wrap cords or
colored tape affixed to each cable. When properly installed, the two tie-wraps on
each cable should straddle the metal cable clip that is closest to the system board.
For the SCSI data cable, the colored tape should be centered directly below that same
cable clip.
1. Route the DC power harness through the metal cable clips.
The two tie-wrap cords on the DC power harness should straddle the cable clip
that is closest to the system board (see Figure 9–22).
2. Route the SCSI data cable through the metal cable clips.
The taped portion of the SCSI data cable should be centered beneath the cable
clip that is closest to the system board (see Figure 9–22).
3. Route the SCSI data cable between the disk drive bracket and the card guide.
Secure the cable under the plastic clips at the rear of the card guide and
connect it to the SCSI backplane.
See Figure 9–22.
4. Connect the DC power harness to the SCSI backplane.
See Figure 9–22.
5. Connect the DC power harness to the rear of the power supply.
6. Reinstall the power supply.
See "Replacing the Power Supply" on page 55.
7. Connect the DC power harness to the diskette drive.
8. Insert the front edge of the system board into the card guide. Lift the rear of
the board slightly and slide it along the card guide until it is fully inserted.
See Figure 9–23.
