Floppy Drive Cable
The removal and replacement of the floppy drive cable is very
easy and may be accomplished without removal of any other com-
ponents. The cable connects to the motherboard at top edge, turns
through 90 degrees, and runs along the back wall of the machine
to the floppy disk drive. Consult the previous photo for routing.
CD-ROM Audio Cable
Removal and replacement of the CD-ROM cable is very easy and may
be accomplished without removal of any other components. The cable
connects to the motherboard at top edge, turns through 90 degrees,
and runs along the back wall of the machine to the CD-ROM drive.
Drive Power/Fan Power Harness
The Drive Power/Fan Power Harness provides power to all drives
on the internal SCSI bus, and to the two drive bay cooling fans.
Removal and replacement may be accomplished without removal
of the Genesis MP Front Panel.
To remove and replace the Drive Power/Fan Power Harness:
1. Back up any data on the hard drives.
2. Unplug the drive bay vent fans, the floppy drive, the CD-ROM
audio, data and power cables from the CD-ROM drive and all
hard drive data and power cables from the drives.
3. Remove the nPOWER card (see section nPOWER
Daughtercard) and any PCI expansion cards (see Chapter 3 of
the Genesis MP User Guide) to ensure their safety.
4. Remove the CD-ROM drive and any other devices in the 5.25˝
drive bays.The floppy drive may be left in place.
5. Make room to work in the Genesis MP chassis: carefully secure
SCSI, floppy and CD-ROM Audio cables out of the way.
6. Take careful note of the routing of the old harness. Refer to the sec-
tion Drive Power/Fan Power Harness Routing for more detail.
7. Clip the cable ties restraining the harness at the 3.5˝ drive bay
and on the chassis support rail near the drive bay fans. Unplug
the harness at the power supply harness connector and careful-
ly remove the old harness.
8. Fish the two longest drive power cables and the fan power cable in
between the 5.25˝ drive bay and the Genesis MP right-hand wall
(as viewed from the front of the machine). Separate the fan power
cable and route it to the fan area. Route the drive power cables
between the 5.25˝ drive bay and the 3.5˝ drive bay assemblies.
