Memory Module Installation/Upgrade
♦
SDRAM DIMM modules supported
– The ES subsystems are able to support
SDRAM DIMMs with memory capacities 256MB and 1GB.
♦
Installation Considerations
– When installing the SDRAM DIMM module, it is
necessary to handle the controller module. The controller board and host IO board
are more susceptible to damage than the other components and must therefore be
handled with extreme care. ALL anti-static precautions specified in
Section 2.3.3
must be strictly adhered to.
♦
Secure Installation
- When replacing the DIMM module, make sure that the new
DIMM module is firmly in place prior to installing the controller module. If the
DIMM module is not firmly in place, the subsystem will not be able to run and the
controller will need to be removed and the DIMM module correctly installed.
♦
Purchasing considerations
– When purchasing an SDRAM DIMM to install on the
controller board, contact the EonStor subsystem vendor.
2.6.2 DIMM Module Upgrade Procedure
To upgrade a DIMM module into the ES U1
6
U subsystem, please follow these steps:
Step 1.
Remove the controller Module
– If the controller module has already been
installed at the rear of the ES U16U chassis it must be removed. To remove the
controller module
loosen the hand retention screws
that appear on the rear
panel of the controller module. Gently open the rear flaps and carefully
pull
the controller module out
of the Chassis. (For more detailed instructions
please see
Chapter 5
)
Step 2.
Remove the IO board retention screws-
The IO board is mounted above the
controller board. The IO board is connected to the controller module with 6
retention screws, two pass through cylinders that are attached directly to the
controller chassis and four pass through the spacers that are connected to the
controller board. (See
Figure 2-1
)
