Mid-plane architecture
The mid-plane consists of two H.110 bus segments that support 17 6U slots (eight 6U modules for one segment
and nine 6U modules for the other). Both H.110 buses have 20.32 mm (0.8 inch) board center-to-center spacing.
The 6U cards are stacked vertically in the chassis. Power is distributed equally to the H.110 bus segments from
both power supplies.
In addition to the 17 6U slots, there are two 3U x 160 mm slots on the front right and two 3U x 160 slots on
the left of the ForeFront Xtreme Chassis. These slots support two Model 6160 or 6161 DC power supply mod-
ules (see
figure 3
on page 15).
On the rear of the chassis, the top left and top right slots are for the rear power entry modules (see
figure 4
on
page 16). The bottom left slot is used for the Patton Model 6103 Alarm Card.
