Supported DIMMs

The DIMMs supported in this blade server are constantly being updated. A list of currently supported and
available DIMMs is in the specification sheets at:
http://www.cisco.com/en/US/products/ps10280/products_data_sheets_list.html
Do not use any memory DIMMs other than those listed in the specification sheet. Doing so 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.

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 1, 2, or 3. Note that each DIMM slot 1 is blue, each slot 2 is black, and each slot 3 is off-white or
beige.
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.
