To remove the processor expansion card (PEC)

Warning: Possible data loss

Ensure that you do not touch the PEC casing to any of the components on the MSC. This may cause shorting, which can erase memory or cause a loss of telephony programming.

If a loss of memory or telephony programming occurs, complete the removal of the PEC, and then restore the data from your backup medium upon reinstallation (see “Installing a processor expansion card (PEC)” on page 314).

Warning: Protect the hardware components against damage from electrostatic discharge. Always wear a grounded wrist strap before you handle components. Always place the components in a static-free container.

1Ensure you have a current data backup of your system (see “Using the backup and restore utility” on page 248).

2Shut down the system (see “Performing a system shutdown” on page 231).

3Disconnect the BCM system from the AC power outlet.

4Attach one end of the grounding strap to your wrist and the other end to a grounded metal surface.

5Completely remove the base function tray from the main unit (see “Removing the base function tray” on page 234). Ensure you do not pinch, stretch, or damage any cables.

6Grasp the top edge of the PEC you want to remove and it pull out. Place the PEC in a safe and static-free container. Refer to Figure 170.
