To connect the drive ribbon cables to the drives in the rear
internal bay, first locate pin 1 on each drive’s connector.
The number “1” or “2” may be stamped on the connector
casing or printed on the drive’s circuit board to identify the
side of the connector containing pin 1. If the number does
not appear on the connector casing, remove the drive and
turn it over to check the circuit board.
Hold the connector on the drive ribbon cable so the red wire
aligns with pin 1 on the drive. Make sure the holes in the
connector fit over all the pins; then push in the connector.
Locate a power supply cable for each drive installed in the
rear internal bay. These cables lead from the power supply
and have multi-colored wires with a plastic connector on
the end. Align the notched corners of the power supply
connector with the drive’s power connector; then push in
the connector.
If you have finished installing or removing drives, replace
the computer’s cover (described in Chapter 3) and see page
4-19 for post-installation instructions.
