BCM200/400 4.0 Installation and Maintenance Guide

To remove the processor expansion card (PEC)

1 Ensure you have a current data backup of your system (see “Using the backup and restore

utility” on page 248).

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

3 Disconnect the BCM system from the AC power outlet.

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

surface.

5 Completely 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.

6 Grasp 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.

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.
