Installation and Setup
Installing the 9921-FS Into a Frame Slot
Notes: • Check the packaging in which the 9921-FS was shipped for any extra items
such as a Rear Module connection label. In some cases, this label is
shipped with the card and to be installed on the Rear I/O connector bank
corresponding to the slot location of the card.
• Depending on option(s) ordered, the 9921-FS unit may consist of a main
card and a piggyback option card. If equipped with a piggyback card, both
cards as a unit will require simultaneous alignment with slot guides and
rear modules in the following steps.
Install the 9921-FS into a frame slot as follows:
1. Determine the slot in which the 9921-FS is to be installed.
2. Open the frame front access panel.
3. While holding the card by the card edges, align the card such that the
plastic ejector tab is on the bottom.
4. Align the card with the top and bottom guides of the slot in which the
card is being installed.
5. Gradually slide the card into the slot. When resistance is noticed, gently
continue pushing the card until its rear printed circuit edge terminals
engage fully into the Rear Module mating connector.
CAUTION
If card resists fully engaging in Rear Module mating connector, check for
alignment and proper insertion in slot tracks. Damage to card and/or Rear
Module may occur if improper card insertion is attempted.
6. Verify that the card is fully engaged in Rear Module mating connector.
7. Close the frame front access panel.
8. Connect cabling in accordance with the appropriate diagram shown in
Table 2-1, “9921-FS Rear Modules” (p. 2-7).
9. Repeat steps 1 through 8 for other 9921-FS cards.
Notes: • The 9921-FS BNC inputs are internally 75-ohm terminated. It is not neces-
sary to terminate unused BNC inputs or outputs.
• External frame sync reference signals are received by the card over a
reference bus on the card frame, and not on any card rear I/O module
connectors. The frame has BNC connectors labeled REF 1 and REF 2
which receive the reference signal from an external source such as a house
distribution.
• To remove a card, press down on the ejector tab to unseat the card from the
Rear Module mating connector. Evenly draw the card from its slot.
10. If network remote control is to be used for the frame and the frame has
not yet been set up for remote control, perform setup in accordance with
Setting Up 9921-FS Network Remote Control (p. 2-15).
