The MVME162 pr5 Vdc power to the remote LED/switch connector
(J4) through a 1A fuse (F1) located near J4. Connector J4 is the interface for a
remote control and indicator panel. If none of the LEDs light and the
ABORT
and
RESET
switches do not operate, check fuse F1.
The MVME162 pr12 Vdc power to the Ethernet transceiver interface
through a 1A fuse (F2) located near diode CR1. The
FUSE
LED lights to indicate
that +12 Vdc is available. When the MVME712M module is used, the yellow
DS1 LED on the MVME712M illuminates when LAN power is available, which
indicates that the fuse is good. If the Ethernet transceiver fails to operate, check
fuse F2.
The MVME162 provides SCSI terminator power through a 1A fuse (F1) located
on the P2 Adapter Board or LCP2 Adapter Board. If the fuse is blown, the SCSI
device(s) may function erratically or not at all. When the P2 Adapter Board is
used with an MVME712M and the SCSI bus is connected to the MVME712M,
the green DS2 LED on the MVME712M front panel illuminates when SCSI
terminator power is available. If the green DS2 LED flickers during SCSI bus
operation, check P2 Adapter Board fuse F1.
