Note
Because any device on the SCSI bus can provide
TERMPWR
,
and because the
FUS
LED monitors the status of several
voltages, the LED does not directly indicate the condition of
any single fuse. If the LED flickers or goes out, check all the
fuses (polyswitches).
MVME1600-011 Base Board
The MVME1600-011 base board pr5Vdc power to the remote
LED/switch connector (J4) through a 1A fuse (F1) located between P1 and
P2. (J4 provides a separate connection point for a remote control and
indicator panel, making it unnecessary to share the LED mezzanine
connector for that purpose.) If none of the LEDs light and the
ABORT
and
RESET
switches do not operate, check fuse F1.
The MVME1600-011 base board pr12Vdc power to the Ethernet
transceiver interface through a 1A fuse (F2) located between P1 and P2.
The
FUS
LED lights to indicate that +12Vdc is available. With the
MVME712M transition module connected, the yellow DS1 LED on the
MVME712M also signals the availability of LAN power, indicating in
turn that the fuse is good. If the Ethernet transceiver fails to operate, check
fuse F2.
The MVME1600-011 base board supplies SCSI terminator power through
a 1A fuse (F1) located on the P2 adapter board. If the fuse is blown, the
SCSI device(s) may function erratically or not at all. With the P2 adapter
board cabled to an MVME712M and with an SCSI bus connected to the
MVME712M, the green DS2 LED on the MVME712M illuminates when
SCSI terminator power is available. If the DS2 LED flickers during SCSI
bus operation, check fuse F1 on the P2 adapter board.
