BCM200/400 4.0 Installation and Maintenance Guide
To install a PEC
1 Disconnect the BCM system from the AC power outlet.
2 Attach one end of the grounding strap to your wrist and the other end to a grounded metal
surface.
3 Decide 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.
4 Line the card up between the rails of the slot. Ensure the card label is face-up.
5 Carefully slide the PEC into the slot until it is firmly seated (see Figure 172 on page 323 ).

tray” on page 244 ).
7 Restore the BCM system to operation. Refer to “Restarting the system after maintenance” on
page 240 .

alignment.
