224Chapter 19 Replacing data cards and processing hardware

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.

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

1If 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.

2Set up the BCM1000 for maintenance, as described in “Shutting down the system hardware” on page 169.

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

4Ensure 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.

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

5Carefully 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.

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