UPGRADING CM9760-KBD FIRMWARE

CAUTION: Only qualified personnel observing electrostatic discharge (ESD) precautions should perform the procedure

below. Always wear a grounding strap connected to an approved grounding source when working on or near exposed
electronic components. Handle circuit boards by their edges.

To upgrade CM9760-KBD firmware to version 8.03, do the following:

1. Using System Manager, upload user-entered keyboard setup information to the System Manager database.

NOTE: This step is necessary to avoid loss of user-programmed keyboard setup information, which is erased when
the KBD is reset later in this procedure. After the KBD is reset, you can download the setup information from
System Manager to the KBD as directed later in this procedure.

2. Log off the KBD and then turn the KBD over so that the bottom of the KBD is visible (refer to Figure 1).

3. Disconnect the KBD from the 9760 system by unplugging the cable from the COM 1 port of the KBD.

4. Set DIP switch 7 to the correct position:

• For compatibility with CM9760-CC1 and CM9760-MGR versions 7.80.003 to 7.80.029, set DIP switch 7 to the OFF
position.

• For compatibility with CM9760-CC1 and CM9760-MGR version 8.03.006 or later, set DIP switch 7 to the ON position.

5. Remove the bottom cover of the KBD:

a. Unscrew nine Phillips screws as indicated in Figure 1. Note that on some KBDs one of the screws has a plastic

retaining nut as indicated in Figure 1. Remove that screw

To remove the screw that has a plastic retaining nut, do the following:
