DIMM
The DIMM (Dual Inline Memory Module) is inserted into the DIMM socket on the CPU blade.
Important
•
The DIMM is easily affected by static electricity. Handle the DIMM after making
your body contact with a metallic frame section of the server to discharge the
static electricity on your body. Do not make bare hands contact with terminals
and components on the DIMM. In addition, do not put the DIMM on a desk
directly. For static notes, refer to “Handling precautions (for Anti-static
Measures)”.
•
Do not use any DIMM not approved by NEC. If an unapproved third party's DIMM
is installed in the server, not only the DIMM but also the CPU blade may be
defected. You will be charged by any repair of a malfunction or defect caused by
such a device within the warranty period.
The CPU blade includes 12 DIMM sockets.
Note
•
Up to 384 GB memory can be added.
•
In the standard configuration, the CPU blade does not contain memory. The memory is
a required option.
