Cisco Cisco MCS 7828-I3 Unified Communications Manager Appliance Guide De Dépannage

There are no specific requirements for this document.

Applicability of this document is restricted to the specific Cisco servers listed in the Introduction.

The information in this document was created from the devices in a specific lab environment. All of the
devices used in this document started with a cleared (default) configuration. If your network is live, make sure
that you understand the potential impact of any command.

For more information on document conventions, refer to the Cisco Technical Tips Conventions.

Suitable memory Field Replacement Units (FRUs) can be purchased from Cisco using the following part
numbers:

MEM−7835I−2.4−256=

• 

MEM−7835I−2.4−512=

• 

Memory can only be installed as a pair of matched dual inline memory modules (DIMMs). Both DIMMs in a
pair must be identical to each other with respect to size, speed, type, and technology. The second pair does not
have to be identical to the first 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:

JEDEC standard PC2100.

• 

Registered (address/control bus delay registers at inputs and outputs).

• 

Double−Data Rate (DDR).

• 

Error−Correcting Code (ECC).

• 

266 MHz (inherent to PC2100) data rate.

• 

CL2.5 (Column Address Strobe clock cycle latency value).

• 

2.5Vdc.

• 

The server supports up to four 2 GB memory modules, yielding a potential maximum of 8 GB. However, the
operating system software delivered with your Cisco Unity system can physically address a maximum of 4
GB.

Follow this procedure to install DIMMS in the MCS 7835I or MCS 7834I system board.

Read the manufacturer safety information and installation guidelines that were included with the
DIMM pair(s).
