Installation
Installation
Installation of the 8941 module is a process of:
• Placing the module in the selected frame slot, and
• Cabling and terminating signal ports.
The 8941 module can be plugged in and removed from an 8900 Series frame
with power on. When power is applied to the module, LED indicators
reflect the initialization process (see
Power Up on page 11 ).
Frame Capacity
The maximum number of 8900 modules allowed in a frame is determined
by frame cooling capacity.
Table 1 provides the power capacity, cooling
capacity, and maximum module count for the 8941 in each frame type.
Note Module capacity figures assume no other modules are in the frame.
If the maximum number of modules a frame can handle is less than ten,
provide as much space between the modules as possible.
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 .
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
Power Supply manual.
The third cell from the right is allocated for the Frame Monitor or 8900NET
Network Interface module. These modules provide health bus monitoring
and control options.
