situation in which the system might lack this global bus timeout: when the
MVME162P2 is not the system controller and there is no global bus
timeout elsewhere in the system.
Multiple MVME162P2s may be installed in a single VME chassis. In
general, hardware multiprocessor features are supported.
Note If you are installing multiple MVME162P2s in an MVME945
chassis, do not install an MVME162P2 in slot 12. The height of
the IP modules may cause clearance difficulties in that slot
position.
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 in the VMEchip2 ASIC includes
four bits that function as location monitors to allow one MVME162P2
processor to broadcast a signal to any other MVME162P2 processors. All
eight registers of the GCSR set are accessible from any local processor as
well as from the VMEbus.
The following circuits are protected by solid-state fuses that open during
overload conditions and reset themselves once the overload is removed:
❏
Indust5V (R58)
❏
IndustryPack +12V (R75)
❏
IndustryPack –12V (R101)
❏
Remote reset con5V (R90)
❏
SCSI term5V (R157)
❏
LAN AUI +12V (R245)

LED illuminates to indicate that all fuses are functioning
correctly. If a solid-state fuse opens, you will need to remove power for
several minutes to let the fuse reset to a closed or shorted condition.
