Frame Capacity
The 8920MUX module can be installed in all 8900 Series frames but with
varying maximum quantities determined by frame cooling capacity.
Table 1 provides the power capacity, cooling capacity, and maximum
module count for each frame type.
Note Module capacity figures assume no other modules are in the frame.
Module Placement in the 8900 Frame
There are ten slot locations in the frame to accommodate either analog or
digital modules. These are the left ten locations. Refer to
Figure 2 .
The two slots on the right are allocated for the power supplies. For addi-
tional information concerning the Power Supply module, refer to the 8900
Frame manual.
The third slot from the right is allocated for the Frame Monitor, or 8900NET
Network Interface module. These modules provide health monitoring and
control options.
