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.
See "Static Precautions" for details of the static electricity.
„
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 server itself may be defected. You will be charged by any
repair of a malfunction or defect caused by such a device within the
warranty period.
