Pelco System 9760 manual Installing a CM9760-VMM Video Output Module, Replacing a CM9760-VMC Card

REPLACING A CM9760-VMC CARD

WARNINGS:

•CM9760-VMC video output card replacement should be performed by qualified personnel only.

•Electrostatic discharge (ESD) precautions must be observed when replacing a CM9760-VMC card. Always wear a grounding strap connected to an approved grounding source when working on or near exposed electronic equipment.

Before replacing a CM9760-VMC card, note the following:

•The CM9760-RPM card can be replaced while the matrix bay is powered on.

•When installed in the matrix bay at the factory according to your system order, the S2 DIP switch and X55 and JP2 jumper settings on the CM9760-RPM card are set in the proper position. You must, however, set DIP switch and jumper settings on a new card as instructed in the procedure below.

To replace the CM9760-VMC card, do the following:

1.Remove the front panel of the matrix bay.

2.Remove the CM9760-VMC card to be replaced by grasping the two card handles and firmly pulling the card out of the connectors on the backplane and associated rear panel card. The card slides out of the slot.

NOTE: 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 removed.

3.Install the new CM9760-VMC card (refer to the Installing a CM9760-VMC Card section). Note that you should set the S2 DIP switch and the X55 and JP2 jumpers on the new card to match the settings on the card being replaced.
