Removing and Installing System Components 69
Replacing a Drive in the Device Bay
1. Observe the safety and ESD precautions at the beginning of this chapter.
2. Remove the front cover. See "Removing the Front Cover" on page 50.
3. Turn off the system by using the power on/off switch on the front panel AND unplug the
AC power cord.
4. Disconnect the power and signal cables from the drive. The connectors are keyed for ease in
reconnecting them to the drive.
5. Slide the drive out. If the drive will be used again, place it in an antistatic protective wrapper.
6. Slide the new drive into position using the guides in the device bay.
7. Connect the power and signal cables from the drive.
8. Install the front cover. See "Installing the Front Cover" on page 51.
Drive Cabling Considerations
This section summarizes device cabling requirements and constraints. The number of devices that
can be installed depends on:
•
The number supported by the bus
•
The number of physical drive bays available
•
The height of drives in the internal bays (1-inch or 1.6-inch high)
•
The combination of SCSI and IDE devices
SCSI Requirements
All SCSI devices must not be terminated except the peripheral at the end of the SCSI cable.
Hard drives usually provide an active termination, while CD-ROM drives do not. Because Intel
recommends putting hard drives only in the internal bays, the SCSI cable should be routed so that
the last device on the cable is a hard drive in the internal bay.

NOTE
Integrating the 5.25-inch peripheral bay can affect EMC compliance and is a
regulated activity. Except as noted here, any changes to the bay
configuration could result in noncompliance with EMC regulations.
CAUTION
To avoid damage to a 5.25-inch peripheral device, ensure the EMI gasketing
provided in the device bay does not bridge any open circuits on the exposed
peripheral device.
