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
Caution! You should not install hard drives in the 5.25-inch
peripheral drive bays 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
.
Drive cables
This section summarizes the 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. 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
