Installation
Installation
Installation of the 8981NR module is a process of:
1. Placing the module in the proper video frame slot, and
2. Cabling and terminating signal ports.
The 8981NR module can be plugged in and removed from a Gecko 8900
video 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 8981NR module can be installed in all Gecko 8900 video 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.
X = Not recommended without forced air cooling.
Module Placement in the Gecko 8900 Video Frame
There are ten cell locations in the video frame to accommodate either
analog or digital modules. These are the left ten locations. Refer to
Figure 1
on page 9 .
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 monitoring and
control options.
