Posted on Updated on


To install a DIMM into the blade server, follow these steps:

Procedure

Step 1: Open both DIMM connector latches.

Step 2: Press the DIMM into its slot evenly on both ends until it clicks into place.

DIMMs are keyed, if a gentle force is not sufficient, make sure the notch on the DIMM is correctly aligned.

Note: Be sure that the notch in the DIMM aligns with the slot. If the notch is misaligned you may damage the DIMM, the slot, or both.

Step 3: Press the DIMM connector latches inward slightly to seat them fully.

Supported DIMMs

The DIMMs supported in this blade server are constantly being updated. A list of currently supported and available drives is in the specification sheets at:

Cisco does not support third-party memory DIMMs, and in some cases their use may irreparably damage the server and require an RMA and down time.

Memory Arrangement

The blade server contains 24 DIMM slots—12 for each CPU. Each set of 12 DIMM slots is arranged into four channels, where each channel has three DIMMs.

1 Channels A-D for CPU 1 2 Channels E-H for CPU 2

DIMMs and Channels

Each channel is identified by a letter—A, B, C, D for CPU1, and E, F, G, H for CPU 2. Each DIMM slot is numbered 0, 1, or 2. Note that each DIMM slot 0 is blue, each slot 1 is black, and each slot 2 is off-white or beige.

The figure below shows how DIMMs and channels are physically laid out on the blade server. The DIMM slots in the upper and lower right are associated with the second CPU (CPU shown on right in the diagram), while the DIMM slots in the upper and lower left are associated with the first CPU (CPU shown on left).
