Replacing a CM9760-RPM Card

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.

NOTE: Before replacing a CM9760-RPM card, you must remove the front panel of the matrix bay and disconnect the associated CM9760-VMC video output card from the connectors on the backplane and from the connector on the CM9760-RPM card that is to be replaced. To disconnect the CM9760-VMC card, grasp the two card handles and firmly pull the card toward you until the card is disconnected.

Unless the audible alarm on the power supply has been disabled, the alarm beeps and the Frame Fault LED flashes red when the CM9760-VMC card is disconnected (refer to the Installing or Replacing a CM9760-VMC Video Output Card section for additional information).

To replace a CM9760-RPM card, do the following:

1.Ensure that the associated CM9760-VMC video output card is disconnected as noted above.

2.Disconnect BNC cables (or ribbon cable, if applicable) from the CM9760-RPM card being replaced.

3.Remove the CM9760-RPM 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 card (refer to the Installing a CM9760-RPM Card section).

After the CM9760-RPM card has been replaced, reconnect the associated CM9760-VMC card by sliding the card toward the rear of the matrix bay until the card is seated firmly with the backplane connectors and CM9760-RPM connector. If the audible alarm on the power supply is enabled, the alarm stops beeping and the Frame Fault LED turns off.

To ensure proper operation of the CM9760-VMC card, reset the card by pressing the Reset button on the card. For about five seconds, the audible alarm on the power supply beeps and the Frame Fault LED flashes red. Then reattach the front panel of the matrix bay.
