Chapter 2 Mechanical Installation
2-26 Profile Video File Server Installation
Connecting SCSI Devices
The Profile Video File Server has a number of connectors for attaching SCSI devices.
There are SCSI connectors on the Master and Slave Enhanced Disk Recorder boards,
on the System SCSI board, and along the top of the rear panel (see Figure 2-20).
Beyond the Master Enhanced Disk Recorder board, standard on all configurations, the
number of SCSI connectors available depends on your configuration. Also, the actual
board locations may vary. Refer to the rear panel labels or Tables 1-2 through 1-6 in
Chapter 1, pages 1-9 through 1-13, to determine the slot location of these boards in
your system.
Figure 2-20. SCSI Cable Connections
The Master Enhanced Disk Recorder board, shown in Figure 2-20, provides a SCSI
A bus and a SCSI B bus. (The SCSI B bus is not present on Profile Video File Servers
which have eight internal media disks, and no Slave Enhanced Disk Recorder board.)
Connect disk-based SCSI devices such as the PDX 218 Disk Expansion chassis to the
SCSI A bus connector on the board at the rear panel. Connect tape-based SCSI
devices such as the PLS 200 Profile Library System to the SCSI B bus connector at
the top of the rear panel.
If installed, the Slave Enhanced Disk Recorder board provides a SCSI C bus and a
SCSI D bus (see Figure 2-20). Connect disk-based SCSI devices to the SCSI C bus
connector on the board at the rear panel. Connect tape-based SCSI devices such as the
PLS200 Profile Library System to the SCSI D bus connector at the top of the rear
panel.
The System SCSI board, shown here in slot J4 (see Figure 2-20) is installed as part of
the optional Profile Library System. If installed, connect the cable from the Profile
Library System to this board. (See the PLS 200 Installation Manual for details about
installing the PLS 200.) Note that the System SCSI board is only used with the
PLS200 and the Ampex DST 412 at this time.
