SCSI Bus Termination
❏
The MVME167 provides SCSI terminator power through a 1-
amp fuse (F1) located on the P2 adapter board. The fuse is
socketed. If the fuse is blown, the SCSI devices may not
operate or may function erratically.
❏
When the P2 adapter board is used with an MVME712M and
the SCSI bus is connected to the MVME712M, the green LED
(DS2) on the MVME712M front panel lights when there is
SCSI terminator power. If the LED flickers during SCSI bus
operation, the fuse should be checked.
❏
Because this board has no provision for SCSI termination,
you must ensure that the SCSI bus is terminated properly. If
you use a P2 adapter, the adapter has sockets (R1, R2, R3) for
terminating the SCSI lines using three 8-pin SIP resistor
networks.
Storage and the Real-Time Clock
For storage of this product, be sure the RTC is put into the
power save mode. This will extend the life of the battery
contained in this part. To put the part into the power save
mode, use the
PS
command of the debugger. For example:
167-Bug>
ps <Return>
(Clock is in Battery Save mode)
167-Bug>
