Nortel Networks BCM1000 manual Installing a PEC

222Chapter 19 Replacing data cards and processing hardware

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.

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.

Follow these steps to correctly install a PEC.

1Decide which slot you are going to install the PEC into on the MSC board.

2Line the card up between the rails of the slot. Refer to Figure 129 on page 221.

3Carefully push the PEC down into the slot until it is firmly seated.

Note: Do not force the card into its slot. If the PEC does not slide in easily, check the alignment.

4Replace the cover.

5Restore the unit to operation. Refer to “Restarting the system” on page 170.
