Other MPUs on the VMEbus can interrupt, disable, communicate with,
and determine the operational status of the processor(s). One register of the
GCSR (global control/status register) set includes four bits that function as
location monitors to allow one MVME2603/2604 processor to broadcast a
signal to any other MVME2603/2604 processors. All eight registers are
accessible from any local processor as well as from the VMEbus.
The MVME2603/2604 VME module draws +5V DC, +12V DC, and
–12V DC power from the VMEbus backplane through connectors P1 and
P2. The 3.3V DC and the processor core voltage power is supplied by the
on-board +5V DC.
MVME2603/2604 VME Module
The MVME2603/2604 VME module furnishes +12V DC and (in
MVME761 I/O mode) –12V DC power to the transition module through
polyswitches (resettable fuses) R34 and R28 respectively. These voltage
sources power the serial port drivers and any LAN transceivers connected
to the transition module. Fused +5V DC power is supplied to the base
board’s keyboard and mouse connectors through polyswitch R30 and to the 14-pin combined LED-mezzanine/remote-reset connector, J1. The FUS
LED (DS5) on the MVME2603/2604 front panel illuminates when all
three voltages are available.
In MVME712M I/O mode, the MVME2603/2604 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 a transition module and with an
SCSI bus connected to the transition module, the green SCSI LED on the
module illuminates when SCSI terminator power is available. If the SCSI
LED on the transition module flickers during SCSI bus operation, check
fuse F1 on the P2 adapter board.
Note Because any device on the SCSI bus can provide the TERMPWR
signal, and because the MVME2603/2604 FUS LED monitors the
status of several voltages, the LED does not directly indicate the
condition of any single fuse. If the FUS LED flickers or goes out,
check all the fuses (polyswitches).In MVME761 I/O mode, the MVME2603/2604 supplies SCSI terminator
power through a polyswitch (resettable fuse) located on the P2 adapter
board.
The MVME2603/2604 base board supplies a SPEAKER_OUT signal to the
14-pin combined LED-mezzanine/remote-reset connector, J1. When J1 is
used as a remote reset connector with the LED mezzanine removed, the
SPEAKER_OUT signal can be cabled to an external speaker. For the pin
assignments of J1, refer to Table 4-1 on page 4-3.
