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 (shown as the “NVRAM failure” event in the PAC
Management Software). 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 ESD Precautions). 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 Unified Storage
System to test its integrity.
Installing the DIMM Module
1.
Remove the controller module (refer to Replacing the Controller Module).
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.
5.
Reinstall the controller module into the chassis (refer to Replacing the Controller Module).
