Replacing memory DIMM chips

You replace a DIMM when the DIMMs fails or when you want to increase the amount of RAM in

the Business Communications Manager.

1 If you still have access to the Unified Manager, shut down the system using the Shutdown

command. For details refer to “Shutting down the system software” on page 168. Otherwise,

skip to step 2.

2 Set up the BCM1000 for maintenance, as described in “Shutting down the system hardware”

on page 169.

3 Attach one end of the grounding strap to your wrist and the other end to a grounded metal

surface.

4 Ensure access to the memory chips is clear of cables and other parts.

• If you have a version 2.5 BCM1000, which has a System Status Monitor board attached to

the front of the housing, you may need to disconnect some of the cables to get at the

memory slots.

• If you have a WAN card in the first PCI slot, you may need to remove it to get adequate

access. Refer to “Removing a data card” on page 218.

5 Carefully push down on the fastening tabs on either side of the DIMM you want to remove.

As you press down on the fastening tabs, the DIMM lifts out of the DIMM slot.

6 Remove the DIMM from the slot by grasping either end, as shown in Figure 129.

Note: There must be at least one DIMM installed in the BCM1000 in order for the system

to function.

Note: If you are adding a new DIMM to the second DIMM slot, go to step 6.
