Nortel Networks 400 4.0, BCM200 manual Increasing the amount of memory

316Chapter 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 172 provides an overview of the process for replacing or adding memory chips.
