Installation Procedures
3.3
SCSI Bus Termination
A SCSI bus must be terminated on both ends of the cable. Termination resistors can be either installed
internally on the mounted drives or with external terminators.
3.3.1
Internal Termination
When the BI-0316 is at the physical end of the SCSI cable, the internal termination option of the
mounted drives can be used. When this option is put to use be sure to enable the terminators on drive
1 in position 1 when a front connection is used. When the VMEbus P2 connector is used, then enable
termination on drive 2 in position 2. When the BI-0316 contains drives with different widths, enable the
termination option for the drive with the wider bus to ensure all signals are terminated.
Jumper block P14 is used to enable the termination options of the drives. The termination option of
drive 1 in position 1 is enabled when pins 1 and 2 of P14 are jumpered. When pins 9 and 10 of P14 are
jumpered then the termination option of drive 2 in position 2 is enabled.
3.3.2
External Termination
For external termination see the discussions in the sections "SCSI-3 Option" on page 2-3 and "SCSI-3
Mixed With SCSI-2 Option" on page 2-4.
