Replacing a CM9760-RPC Card
NOTE: Before replacing a CM9760-RPC card, you must remove the front panel of the matrix bay and disconnect the associated CM9760-VCC
video input card from the connectors on the backplane and from the connector on the CM9760-RPC card that is to be replaced. To disconnect the
CM9760-VCC card, grasp the two card handles and firmly pull the card toward you until the card is disconnected (refer to the Installing or
Replacing a CM9760-VCC Video Input Card section for additional information).
To replace a CM9760-RPC card, do the following:
1. Ensure that the associated CM9760-VCC video input card is disconnected as noted above.
2. Disconnect BNC and downframe cables, as applicable, from the CM9760-RPC card being replaced.
3. Remove the CM9760-RPC card by loosening the screw at the top and bottom of the card and then pulling the card toward you until it is out
of the frame.
4. Install the new CM9760-RPC card (refer to the Installing a CM9760-RPC Card section). Note that you should set the termination jumpers on
the new card to match the jumper positions on the card being replaced.
After the CM9760-RPC card has been replaced, reconnect the associated CM9760-VCC card by sliding the card toward the rear of the matrix bay
until the card is seated firmly with the backplane connectors and the CM9760-RPC connector. Note that, unless the audible alarm on the power
supply has been disabled, the alarm beeps twice and the Frame Fault LED flashes red twice. Then reattach the front panel of the matrix bay.
WARNINGS:
• Rear panel card replacement should be performed by qualified personnel only.
• Electrostatic discharge (ESD) precautions must be observed when replacing a rear panel card. Always wear a grounding strap
connected to an approved grounding source when working on or near exposed electronic equipment.
