2.4 Installing I/O Equipment

2.4.1 Installing one external IDE (3.5" HDD/CD-ROM) device

and an external FDD

Three connectors are located on the rear panel above the PPC-A84's I/O
output connectors. The 40-pin connector is for an external slave IDE devices
(3.5 hard drive or CD-ROM). A 34-pin FDD connector is for an external
FDD. Any combination of 5 1/4" (360 KB and 1.2 MB) and/or 3 1/2"
(720 KB, 1.44 MB, and 2.88 MB) drives can be attached. The 4-pin connec-
tor provides +5 Vdc and +12 Vdc to both IDE device and FDD.
The following are instructions for installation:
1. Adjust the jumper setting of your IDE device to be a slave IDE device.
2. Unscrew the two attachment screws and detach the metal cover.
3. Connect the single end of the appropriate 40-pin cable to the PPC-A84
and connect the remaining end to your IDE device.
4. Connect one end of a 34-pin daisy-chain drive connector cable to the
PPC-A84 and connect the remaining end to your FDD.
5. Connect the 4-pin Y-power cable to PPC-A84 , and the remaining two
ends to your IDE device and FDD.

Note: The 40-pin connector is a Primary Slave channel. The

jumper setting of the IDE device should be adjusted to be a

slave.
