Installing a Rear Module
Notes: • This procedure is applicable only if a Rear Module is not currently
installed in the slot where the 9921-FS is to be installed.
• Where options are furnished using a piggyback card mounted to 9921-FS
main card, base Rear Module must be installed in frame location such that
Rear Module interfaces with base card. Expansion Rear Module must be
installed in frame location such that Rear Module interfaces with expansion
(piggyback) card (see Figure 2-3).
• Note that some Rear Modules and labels have several ventilation holes. To
allow maximum ventilation, it is recommended to place the label fully over
connectors such that label is flush with rear module and holes are not
obscured. Also, when a card is not installed in a slot, it is recommended that
the supplied blank cover be used to preserve proper forced ventilation
flow-through.
The full assortment of 9921-FS Rear Modules is shown and described in
9921-FS Rear Modules (p. 2-7). Install a Rear Module as follows:
1.
On the frame, determine the slot in which the 9921-FS is to be installed.
2.
In the mounting area corresponding to the slot location, install
Rear Module as shown in Figure 2-2.
3.
If an expansion Rear Module is to be installed, install it adjacent to the
base Rear Module as shown in Figure 2-3.
