Chapter 1: Working Inside the System
3. Connect a signal cable to the drive. The connectors are keyed and can be inserted in
only one way.
■ SCSI drive: Attach connectors on the cable to the SCSI device or devices you
are installing.
■ IDE drive: The baseboard has one IDE connector. It can support an IDE signal
cable up to 22 inches long. See “Drive Cabling Considerations” on page 13 for
the cable dimensions.
4. Close the front bezel.
Removing a 5.25-inch Peripheral from the Front Bay
1. Observe the safety and ESD precautions at the beginning of this chapter.
2. Open the front bezel by rotating its right side out and to the left.
3. Disconnect the power and signal cables from the drive.
4. The drive has two protruding plastic, snap-in rails attached. Squeeze the rail tabs
toward each other as you carefully slide the drive forward out of the bay, and place
it on an antistatic surface.
5. Remove and save the four screws and two slide rails.
6. If you leave the bay empty, install a stainless steel EMI shield on the bay for proper
cooling and airflow.
7. If youdo notreplace the device with another SCSI device, and it wasinstalled atthe
end of the SCSI signal cable, modify the cable and termination arrangement so that
a proper termination exists at the end of the cable (it can be a termination device
only, not necessarily a SCSI peripheral).
8. Close the front bezel.
