Left-side cover

To remove the server left-side cover, complete the following steps:

1.Read the safety information that begins on page vii and the guidelines in “Handling static-sensitive devices” on page 9.

2.Using the supplied key, unlock the left-side cover.

3.Pull the cover-release latch down and rotate the top edge of the cover away from the server.

Attention: For proper cooling and airflow, replace the cover before you turn on the server. Operating the server for extended periods of time (more than 30 minutes) with the cover removed might damage server components.

4.Remove the left-side cover from the server.

Installing a memory module

The following notes describe the types of dual inline memory modules (DIMMs) that the server supports and other information that you must consider when you install DIMMs:

vThe server supports 667 MHz, 1.8 V, 240-pin, PC2-5300 double-data-rate (DDR) II, fully buffered synchronous dynamic random-access memory (SDRAM) with error correcting code (ECC) DIMMs. These DIMMs must be compatible with the latest 5300 SDRAM Fully Buffered DIMM (FBD) specification. For a list of supported optional devices for the server, go to http://www.ibm.com/servers/ eserver/serverproven/compat/us/.

vWhen you install additional DIMMs, be sure to install them in pairs. The DIMMs in each pair must be the same size and type. You can mix compatible DIMMs from various manufacturers.

vThe second pair does not have to contain DIMMs of the same size, speed, type, and technology as the first pair when the server is operating in a non-mirroring mode.
