Removable Media Devices - NEC EXPRESS5800/180Ra-7 User Manual

Removable Media Devices

A CD-ROM drive is always mounted in bay A. Any SCSI removable media
device can be installed in peripheral bays B, and C. The SCSI devices should be
installed in the first available bay from the bottom (bay C).
Figure 4-44 illustrates the recommended removable media configuration. The
5 1/4-inch bays are intended to hold CD-ROM, tape, or other removable media
drives. SCSI drives in the 5 1/4-inch bays receive control signals from
channel A of the SCSI controller on the system I/O board.
When installing or replacing a 5 1/4-inch device consider the following:
The SCSI terminator of an installed 5 1/4-inch device must be set to OFF
!
and assigned a unique ID (refer to its device manual for setup operations).
When installing an internal auto-change DAT (DDS-3), use the power
!
branch cable attached to the device.
When installing an internal auto-change AIT, use the power relay cable
!
attached to the device.
Observe that when installing an internal DLT device the front panel of
!
the DLT will protrude approximately 1 cm from the front bezel, this will
not affect the operation.
When installing a Narrow-SCSI device use the 68 pin (Wide-SCSI cable
!
connector) to 50 pin (Narrow-SCSI cable connector) conversion adapter
provided with your system.
Note:
5 1/4-inch device tray. All devices must have terminators
removed.
Hard disk drives cannot be installed in a 5 1/4-inch external bay because the
drive generates EMI, is more susceptible to ESD, and does not have sufficient
cooling.
A 1.44 MB diskette drive is always mounted in bay D.
The SCSI termination resistors are located in the
