Installation
Installation of the 8920ADT module is a process of:
1. Placing the module in the desired frame slot, and
2. Cabling and terminating signal ports.
The 8920ADT module can be plugged in and removed from an 8900 Series
frame with power on. When power is applied to the module, LED indica-
tors reflect the initialization process (see
Power Up on page 6 ).
Frame Capacity
The 8920ADT 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 cell locations in the frame to accommodate either analog or
digital modules. These are the left ten locations. Refer to
Figure 1 on page 3 .
The two cells 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 cell from the right is allocated for the Frame Monitor or Network
Interface controller modules. These modules provide health monitoring
and control options.
