External Terminator Installation
The illustration shows two different types of external SCSI connectors.
1.Configuration"A" shows an extended external SCSI connector and bail locks for
holding the terminator in place. This configuration is used on several different
models of computers sold by Alpha Micro, including AM-990 and AM-1600
computers. The terminator is installed by sliding it over the connector and then
latching the bail locks into the notches in the terminator.
2.Configuration"B" shows a flush mounted external SCSI connector. This is the
configuration used on pedestal style AM-2000M computers and AM-2001
subsystems. In this configuration, the terminator inserts into a cutout in the sheet
metal and over the SCSI connector. The terminator is held in place with two
#4screws and washers.
A.1.1Termination Procedure (Without External Terminator)
1.For all AM-2000M computers, the last SCSI device attached to the connector
farthest down the cable away from the CPU board must have its terminators
installed. If only one SCSI device is installed, that device must be terminated.
