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.
