Section 2. Installing Your PlexCombo
Figure 15: Installing Mounting Rails (if Needed)
6. Plug one connector of the IDE cable into the IDE connector on the rear panel of
the drive before you insert the drive into your computer. ( If the PlexCombo is
the only drive connected, you must use one of the end connectors.) Then thread
the cable through the front of the open bay and back toward the motherboard.
The drive should slide smoothly into the bay. If it does not, check for
obstructions in the bay and ensure the side rails are attached properly.
7. If not already connected, attach the other end of the IDE ribbon cable to the
connector on the motherboard.
Figure 16: Connecting the IDE Ribbon Cable
CAUTION: It is easy to accidentally plug your IDE ribbon cable upside down into both
your drive and the motherboard. Be sure you match the red stripe along one side of
the IDE cable to Pin 1 on the motherboard and Pin 1 on the drive. (Pin 1 on the drive
is closest to the power connector.) Each connector on the ribbon cable has a "key" in
the middle. This key should fit into a slot in the middle of each connector of the
motherboard, your PlexCombo, and any other internal IDE peripherals.
