Installing a PEC
When you replace or add PECs, ensure you have followed the directions for shutting down the
system from the previous section. Also ensure you have a current data backup of your system.
Follow these steps to correctly install a PEC.
1 Decide which slot you are going to install the PEC into on the MSC board.
2 Line the card up between the rails of the slot. Refer to Figure 129 on page 221.
3 Carefully push the PEC down into the slot until it is firmly seated.
4 Replace the cover.
5 Restore the unit to operation. Refer to “Restarting the system” on page 170.
Warning: Possible data loss
Ensure that you do not touch the PEC casing to any of the components on the MSC as you
are sliding it into position. This may cause shorting to occur, 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.
Note: Do not force the card into its slot. If the PEC does not slide in easily, check the
alignment.
