Chapter 2: Installation

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.

2.7.2DIMM 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)
