Peripheral Drives

This section provides information and instructions for installing and removing devices from the
5.25-inch peripheral bay and the media bay.

Preliminary Considerations

CAUTION
You should not install hard drives in the 5.25-inch peripheral drive bay for two
reasons:
The drives cannot be properly cooled in this location.
The total EMI from the server might exceed allowable limits, because the hard drive
generates additional EMI.
To avoid damage to a 5.25-inch peripheral device, ensure the EMI gasket
provided in the device bay does not bridge any open circuits on the exposed
peripheral device.
Drive Cables
This section summarizes drive cable requirements and constraints. The number of peripheral drives
you can install depends on:
The number supported by the bus
The number of drive bays available
The height of drives in the bays (1-inch or 1.6-inch high)
The combination of SCSI and IDE devices
IDE Requirements
The server includes an IDE controller and a cable that supports two devices. One of the two
connectors on the cable is already used for the CD-ROM drive. The CD-ROM device is configured
for Cable Select (CS) and is at the end of the cable; this defines the CD-ROM as the IDE master. If
you install a second IDE device, and it is jumpered for Cable Select, connect the device on the
middle IDE connector to configure the device as IDE slave, or at the end of the cable to configure the
device for IDE master.
SCSI Requirements
The server includes a two-channel SCSI controller. One channel is used for the hot-swap drive bay.
You may use the second channel for SCSI devices in the peripheral bay. SCSI cabling and
connections must meet the SCSI bus specification. Otherwise, the bus might be unreliable and data
might become corrupted or devices might not work properly.
EMC Compliance of 5.25-inch Removable Media Device Bays
Integration of the 5.25-inch peripheral drive bay can affect EMC compliance and is a regulated
activity. Except as noted here, any changes to the bay configuration could result in non-compliance
with EMC regulations in your area.
