Chassis Description and Specifications

The MVME956AC chassis is designed for industry-standard 3-row VME
modules and VME64X modules not requiring +3.3Vdc backplane power.
The chassis accommodates five additional peripheral drive and houses a
VME module card cage with 12 VME bus slots. The front panel opening
accommodates the five 5-1/4-inch, half-height SCSI peripheral devices.
The control for the chassis is an ON/OFF power switch.When the switch
is in the OFF position, power to the modules is removed but the primary
side of the power supply remains energized. Power is supplied by an
internal 550 watt wide-ranging power supply, which is mounted vertically
toward the rear of the chassis. There is provision for 17 rear panel-mounted
80 mm interface modules.
Three DC-powered fans provide forced air cooling for the power supply,
mass storage enclosure, and VME modules. Convection cooling is used for
the rear-mounted modules.
The rear of the chassis supports standard double-high Eurocard panels and
80 mm modules such as MVME7XX series modules.
