Memory Module Installation 2-5
2.7. Memory Module Installation
The SR controller comes without a DIMM memory module. It is therefore necessary for
a separately purchased DIMM module to be installed.
2.7.1 Selecting the DIMMs
When purchasing the DIMM modules, the following factors must be considered:
♦ Supported SDRAM DIMM modules: The SR controllers support SDRAM DIMMs
with memory capacities between 128MB and 1GB with ECC support.
♦ Installation considerations: When installing the SDRAM DIMM module, it is
necessary to handle the controller board. The controller board is susceptible to
damage and must therefore be handled with extreme care. ALL anti-static
precautions specified in Section 2.3.2 must be strictly adhered to.
♦ Secure installation: When installing the DIMM module, make sure that the DIMM
module is firmly in place prior to installing the controller. If the DIMM module is
not firmly in place, the controller will not be able to run and 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 SR controller vendor.
2.7.2 DIMM Module Installation Procedure
To install a DIMM module into the SR controller, please follow these steps:
Step 1. Remove the chassis top cover. Before installing the DIMM module,
remove the chassis top cover. For further instructions on how to remove
the top cover, please refer to Section 2.6.2.
Step 2. Insert the DIMM module. Once the chassis top cover has been removed,
install the DIMM module. To do this, first push the white clips on either
side of the DIMM module in an outward direction. Next, align the
DIMM module with the DIMM slot. Then, gently push the DIMM
module into the slot. The white clips should automatically close and
secure the DIMM module into the DIMM slot. (See Figure 2-2)
