BCM expansion unit (BCM400 only)

In addition to a main unit, the BCM400 system can have one expansion unit. The expansion unit is not compatible with the BCM200 system. The BCM expansion unit contains six additional bays for MBMs.

The supplied DS256 cable is 5 m (16 ft.) long and connects into a DS256 port on the MSC of the main unit, and into a DS256 port on the center panel of the expansion unit (see Figure 21). Use of any other cable is not supported. See “Installing an expansion unit” on page 101 for more information on installing a expansion unit.

Note: The number of MBMs that you can install is determined by the number of DS30 buses required by the MBMs and the number of buses available.

Refer to Chapter 8, “Installing a media bay module (MBM),” on page 105.
