If the new card is replacing an old card, you should first refer to the section Removing
an Option Card. Option cards are installed from the rear of the unit.
First undo the two knurled locating screws attached to the blanking plate and remove
the plate. Then, taking care to align the edges of the new Option Card PCB with the
card guides inside the unit, slowly slide in the card until the bezel is approximately 6mm
from the rear panel. One final push will locate the connector internally and the bezel
should lie flush with the rear panel. Tighten up the two knurled locating screws on the
new plate.

fitting Options Cards (see Safety Instructions)
Prepare the card for hot-swap. If the option card is still active, press the alert button and
wait for the appropriate LED on the front panel to go red, indicating the card is in

Power Supply Card

The A/C PSU Card (p/n VI68202) has no user-serviceable parts inside. It presents a
single IEC inlet, fan and ON-OFF switch to the rear panel and provides a single 13.2V DC
rail internally to the V200 backplane. A complete PSU assembly comprises an A/C
module which is screwed to two runners and a control card which carries high-current
connectors for the DC output.
PSU cards may only be used in the two rightmost slots, Bay I and Bay J. One PSU card is
able to supply all of the power for a full chassis of cards but may be used in conjunction
with a second card for redundant backup. Note that both cards must be switched on
and their corresponding front panel LEDs (the rightmost LEDs) should be green for this
facility to operate. The active PSU card supplies all of the power; in the event of a failure
the standby card will seamlessly take over without interruption.
