Increasing The Amount Of Memory; Removing The Dual In-Line Memory Module (Dimm) Card - Nortel BCM200 Installation And Maintenance Manual

318 Chapter 24 Replacing data cards and processing hardware
The BCM system is equipped with 256 MB of random access memory (RAM). The memory
resides on a dual in-line memory module (DIMM) on the main card. The main card contains space
to add a second DIMM, or you can upgrade the existing DIMM.
Figure 173 provides an overview of the process for replacing or adding memory chips.

amount of RAM in the BCM main unit.
Note: There must be at least one DIMM installed in the BCM main unit for the system to
function.
