Coprocessor
SCSI interface
details
The coprocessor SCSI (hard disk drive) interface connection is made at the
coprocessor board free edge. From there it is routed:
• Through a cable to the Hard Disk Drive tray (HDDT) internal circuit
board,
• Through the internal HDDT circuit board to disk drive interface cables
and also through the backplane to the HDDT I/O board,
• Through the HDDT I/O board to a cable connector.
The SCSI interface connector on the HDDT I/O board has a terminator
assembly installed if no optional DAT drive or optional CD-ROM is
connected. If one or both of the optional devices is connected, the device at
the end of the cable must be pinned to provide the bus termination.
Coprocessor
hardware
identification
number
Each coprocessor has a unique software visible hardware identification
number manufactured into the board. This hardware identification number
is tied directly to the user of the optional Honeywell Kinet software license.
Only users requiring DECnet communications support will have Kinet
software installed on the coprocessor system.
The Honeywell license key information (correlated to the coprocessor
hardware identification number) is obtained from Honeywell prior to
system installation. The customer creates a license file based on this
information. This activity is not required for A
