12. Remove the power supply.
See Section 8.1.1 “Removing the Power Supply.”
13. Disconnect the DC power harness (labeled P1) from the power supply and remove
the harness from the system chassis.
9.5.2 Replacing the Peripherals DC Power Harness
Markers on the DC power harness will help you to route the harness through the
cable clips. The markers are either tie-wrap cords or colored tape affixed to each
cable.
When properly installed, the two colored tape marks on the P1 (power supply)
harness should straddle the metal cable clips on the chassis wall that is closest to the
system board. The P2 (CD-ROM drive) harness connects to the CD-ROM DC power
connector. The second colored tape mark (farthest from the P3 connector) on the P3
(SCSI backplane) harness should be centered under the second plastic cable guide
clip. The P4 (diskette drive) harness should be threaded through the chassis wall
with the diskette data cable, and secured under the first metal cable clip on the
chassis floor.
