8-20 System Upgrade

DIMM

The DIMM (dual inline memory module) is installed to the DIMM socket in the CPU/IO module on the NEC Express5800/ft series.

The CPU/IO module board is equipped with six sockets. Two DIMMS are installed on the DIMM slot A1 and B1 as standard equipment. (The standard DIMMs can be replaced with other DIMMs.)

320Fa-L and 320Fa-LR models: 512MB DIMM×2

DIMMs should be installed to these sockets, starting from the lowest socket number.

TIPS:

„You can add memory up to:

320Fa-L and 320Fa-LR models: 6GB (1GB x 6)

„In the error messages and logs in POST NEC ESMPRO, or Off-line Maintenance Utility, the DIMM connector may be described as “group.” The number next to “group” corresponds to the connector number shown in the figure on the next page.

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 onboard parts with a bare hand or place the DIMM directly on the desk. For more information on static electricity, see “ANTI-STATIC MEASURES.”

„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.

„Before adding or removing DIMMs, power off the server and detach the CPU/IO module.

„Make sure to read “ANTI-STATIC MEASURES” (page 8-3) and “PREPARING YOUR SYSTEM FOR UPGRADE” (page 8-4) before installing or removing options.
