13Install the MSC in the correct PCI riser card connector. See “To install the media services card (MSC)” on page 306.

14Install the two mounting screws that secure the MSC to the base function tray extension (at the rear of the MSC). See Figure 164.

15Position the WAN card (if applicable) in the top PCI riser card connector. See “Installing the WAN card” on page 302.

16Partially install the base function tray in the main unit.

17Connect the DS30 connectors to the MSC.

18Position the PCI cover plate on the front of the base function tray so that the base function tray and cover plate screw holes align.

19Position the PCI cover plate locking screw in the PCI cover plate. Tighten the PCI cover plate locking screw until the plate is firmly set in place (see Figure 163).

20Push the base function tray completely into the main unit (see “To install the base function tray” on page 236). Ensure you do not pinch or damage any cables.

Replacing the processor expansion card (PEC)

This section describes how to replace the processor expansion card (PEC) in the BCM200 and BCM400 main units. This section contains the following procedures:

•“To remove the processor expansion card (PEC)” on page 313

•“Installing a processor expansion card (PEC)” on page 314

•“Removing the dual in-line memory module (DIMM) card” on page 316

The BCM200 is equipped with one PEC III mounted on the media services card (MSC). The BCM400 is equipped with two PEC IIIs mounted on the MSC. The PECs provide signal processing capabilities for such applications as voice mail and IP telephony applications.

Figure 169 provides an overview of the process for replacing a PEC.
