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.

Increasing the amount of memory
To increase the amount of memory in the system, you can:
• add another DIMM to the second DIMM slot.
• replace current DIMM with a DIMM that contains more RAM.
Removing the dual in-line memory module (DIMM) card
Use this procedure to remove a DIMM when the circuit fails or when you want to increase the
amount of RAM in the BCM main unit.
Danger: Risk of shock
Disconnect the power cord, telephone cables, and network cables before opening the
computer. Read and follow installation instructions carefully.
Caution: Use only a Nortel-approved replacement. Contact your account representative
for the current list of approved replacement parts.
Note: There must be at least one DIMM installed in the BCM main unit for the system to
