DIMM
The DIMM (dual inline memory module) is installed to the DIMM socket on motherboard in the CPU/IO module
of the server.
The motherboard of CPU/IO module has 16 sockets for DIMM.
Tips
•
Maximum memory capacity depends on server model as follows:
Up to 256GB (16GB x 16)
•
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 slot 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.
•
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.
