Installing a processor expansion card (PEC)

When you replace or add PECs, ensure you follow the directions for shutting down the system. Ensure you have a current data backup of your system. This procedure assumes the base function tray is completely removed from the main unit.

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 this occurs, complete the installation of the PEC, and then restore the data from your backup medium.

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.
