system controller. A local reset may be generated by the
RESET
switch, a
power-up reset, a watchdog timeout, a VMEbus
SYSRESET
*, or a control bit in
the GCSR.

ote
For an MVME162 without the VMEbus option (i.e., with no
VMEchip2), the LCSR control bit is not available to reset the
module. In this case, the watchdog timer is allowed to time
out to reset the MVME162.
Front Panel Indicators (DS1 - DS4)
There are eight LEDs on the MVME162 front panel:
FAIL
,
STAT
,
RUN
,
SCON
,
LAN
,
FUSE
,
SCSI
, and
VME
.
❏
FAIL
LED (red). Lights when the BRDFAIL* signal line is active. Part of
DS1.
❏
STAT
LED (yellow). Driven by the MC68040 status lines on the MVME162.
Lights when a halt condition from the processor is detected. Part of DS1.
❏
RUN
LED (green). Lights when the local bus TIP* signal line is low. This
indicates one of the local bus masters is executing a local bus cycle. Part of
DS2.
❏
SCON
LED (green). Lights when the VMEchip2 in the MVME162 is the
VMEbus system controller. Part of DS2.
❏
LAN
LED (green). Lights when the LAN chip is local bus master. Part of
DS3.
❏
FUSE
LED (green). Lights when power is available to the transceiver
interface (the MVME162 su12V power to the LAN Ethernet
transceiver interface through a fuse). Part of DS3.
❏
SCSI
LED (green). Lights when the SCSI chip is local bus master. Part of
DS4.
❏
VME
LED (green). Lights when the board is using the VMEbus (VMEbus
AS* line asserted by the VMEchip2) or when the board is accessed by the
VMEbus (VMEchip2 is the local bus master). Part of DS4.
