9-56 Upgrading Your Server
Installation
Install a DIMM in the following procedure.
IMPORTANT:
„
The DIMM is extremely sensitive to static electricity. Make sure to
touch the metal frame of the server to discharge static electricity
from your body before handling the DIMM. Do not touch the
DIMM terminals or on-board parts by a bare hand or place the
DIMM directly on the desk. For static notes, see the section "Anti-
static Measures" described earlier.
„
Make sure to use the DIMM authorized by NEC. Installing a third-
party DIMM may cause a failure of the DIMM as well as the server.
Repair of the server due to failures or damage resulted from
installing such a board will be charged.
„
Install two additional DIMMs for each group because the server
uses interleaved memory. If DIMMs of different specifications* are
installed in a group, the server does not operate normally.
* DIMM specification is shown on the label attached to the DIMM as
follows:
Example: Frequency of 400 MHz, buffered, capacity of 1GB, row
address of 14 bits, column address of 11 bits, and
single rank
