5.25-Inch Peripheral Drives

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

Preliminary Considerations

You should not install hard drives in the 5.25-inch peripheral
drive bays, as the drives cannot be properly cooled in this
location. Also, the total EMI from the server might exceed
allowable limits, because the hard drive generates additional
EMI.

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.

SCSI Requirements

The server includes a two-channel SCSI controller. One channel is used for the
hot-swap drive bay. If you don't use the second channel for adding a second
hot-swap drive bay, you may use that 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.
