To install a PEC

1Disconnect the BCM system from the AC power outlet.

2Attach one end of the grounding strap to your wrist and the other end to a grounded metal surface.

3Decide which slot you are going to install the PEC into on the MSC. If you have more than one card holder (BCM400), completely populate one card holder at a time.

4Line the card up between the rails of the slot. Ensure the card label is face-up.

5Carefully slide the PEC into the slot until it is firmly seated (see Figure 171 on page 315).

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