Installation
8900 modules are interchangeable within the module cells. There are 10
BNC connectors in each cell’s I/O group. The functional assignment of
each connector in a group is determined by the module that is placed in
that cell. The maximum number of modules an 8900 frame can accept is ten.
illustrates the rear connector plate for an 8900 Series frame.
Frame Capacity
The maximum number of 8900 modules allowed in a frame is determined
by frame cooling capacity.
provides the power capacity, cooling
capacity, and maximum module count for the 8920DAC 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.
Figure 2. 8900 Series Frame Rear Connectors
8900 modules can be inserted and removed while the frame is powered. To
install a module in the frame:
1.
Insert the module, connector end first, with the component side of the
module facing to the right and the ejector tab to the top.
2.
Verify that the module connector seats properly against the backplane.
3.
Press the ejector tab in to seat the module in place.
