When the remote switch and cable is installed, the MVME147 can
be reset by the remote switch or by the front panel RESET switch.
FAIL Indicator (DS1)
The red FAIL LED, DS1, indicates the status of the BRDFAIL bit in
the VMEchip. The FAIL LED lights when the BRDFAIL bit is set or
when watchdog time-out occurs in the PCC. Also, if the FAIL LED is
lit and SYSFAIL inhibit bit in the VMEchip is not set, the MVME147
drives SYSFAIL on the VMEbus.
STATUS Indicator (DS2)
The yellow STATUS LED, DS2, lights whenever the MC68030
STATUS* pin is low. When the yellow LED is fully lit, the processor
has halted.The green RUN LED, DS3, is connected to the MC68030 address
strobe (AS*) signal and indicates that the MPU is executing a bus
cycle.
SCON Indicator (DS4)
The green SCON LED, DS4, lights when the MVME147 is the
VMEbus system controller.

(Green) MVME147 Status
off off off No power is applied to the module, or the MPU is not the
current local bus master.
off off ON MPU is waiting for a cycle to complete.
off ON (bright) off MPU is halted.
off ON (normal) off MPU is executing out of its onchip cache only.
off ON ON Normal operation.
ON off off MPU is not current local bus master and is not executing
out of onchip cache. Also, [BRDFAIL] has not been
cleared since reset or has been set by software.
ON off ON [BRDFAIL] has not been cleared since reset or has been set
by software. Also, MPU is waiting for a cycle to complete.
ON ON (bright) off MPU is halted and [BRDFAIL] has not been cleared since
reset or has been set by software.
ON ON (normal) off [BRDFAIL] has not been cleared since reset or has been set
by software. Also, MPU is executing out of onchip cache
only.
ON ON ON [BRDFAIL] has not been cleared since reset or has been set
