Replacing Memory Module(s)
The controller comes with pre-installed DRAM module(s). You may upgrade it or
replace it when the original module malfunctions (sh
own as the “NVRAM failure”
event in EonOne). If you have two modules installed, please identify correctly which
one has failed before proceeding with the replacement procedure.
WARNING
If you are installing only one or replacing just one DRAM module, with the I/O ports
pointing at you, always install to the DRAM slot on the right (blue slot). Follow the
ESD Precautions (refer to
). Contact your system vendor for
selecting a compatible DRAM module. Reusing the DRAM module removed from a
failed controller is not recommended unless you have a similar system to test its
integrity.
Installing the DIMM Module
1. Remove the controller module (refer to

2.
Wait for one minute
for the remaining electricity on the main board to disperse.
3. Push down the clips on the sides of the DIMM socket. The DIMM will eject
automatically from the socket.
4.
Insert the replacement module
. Make sure the side clips are in the open
positions. Align the DIMM module with the socket and firmly push the DIMM
module into the socket. The side clips will close automatically and secure the
DIMM module into the socket.
