Determine the location for the new DIMM pair(s): J1 and J2 for the first pair, J3 and J4 for the second
pair.

3.
Install the DIMM pair(s) in the proper connectors.
4.
Save the new configuration information only if you are replacing a faulty DIMM that was marked as
Disabled in the Configuration Setup Utility program Memory Settings menu. In this case, re−enable
the memory row or reload the default memory settings.

Memory can only be installed as a pair of matched dual inline memory modules (DIMMs). Both DIMMs in
any pair must be identical to each other with respect to size, speed, type, and technology. Each pair does not
have to be identical to any other pair. If you do not purchase memory through Cisco, you can use DIMM pairs
from different manufacturers, if necessary, as long as they meet the following requirements:

The server supports up to six 2 GB memory modules, yielding a potential maximum of 12 GB. However, the
operating system software delivered with your Cisco Unity system can physically address a maximum of 4
GB.

Install DIMMs in the MCS 7835H or MCS 7845H System Board
Use this procedure to install the DIMMs in the MCS 7835H or MCS 7845H system board.
Shut down the server according to the manufacturer instructions.
1.
Extend the server from the rack, if applicable.
2.
Remove the access panel.
3.
Open the DIMM slot latches.
4.
Install the DIMM pair(s) in the proper location.
DIMMs must be installed into both slots in a single bank. Install DIMMs in sequential order (DIMM
slots are numbered sequentially 1 through 6 and paired banks are identified by the letters A, B, and
C.) If you are upgrading memory, install DIMM pairs into banks starting with bank B.

If you are installing DIMMS for online spare memory, use the RSBU to configure online spare
memory support.
