Installing Memory

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

Procedure

Step 1

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

Step 2

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

The DIMMs supported in this blade server are constantly being updated. A list of currently supported and

available DIMMs is in the

Do not use any memory DIMMs other than those listed in the specification sheet. Doing so may irreparably

damage the server and require down time.

Memory Arrangement

The Cisco UCS B420 high-performance blade server contains 48 slots for installing DIMMs—12 for each

CPU. Each CPU has 12 DIMM slots spread over 4 channels. This blade server needs at least one DIMM

attached to all populated CPUs. DIMMs installed in slots for an absent CPU will not be recognized. For

optimal performance, distribute DIMMs evenly across all CPUs. DIMM connector latches are color coded

blue, black, and white, and the DIMMs must be installed in that order.

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.
