CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. See your Product Information Guide for complete information about safety precautions, working inside the computer, and protecting against electrostatic discharge.

1Ensure that the SAS interface cable connector is facing toward the hard- drive bays and align the backplane board with the left- and right-securing slots. See Figure 3-17.

2Ensure that the backplane board center latch is engaged with the hard drive cage. See Figure 3-17.

System Memory

The six memory module sockets are located to the right side of the system board and can accommodate 512 MB to 24 GB of registered PC-4200/5300, 533/667-MHz, DDR2 memory with ECC. See Figure 6-1 for the location of the memory module sockets.

You can upgrade the system memory by installing combinations of 512-MB, 1-GB, 2-GB, and 4-GB memory modules. You can purchase memory upgrade kits from Dell.

NOTE: The memory modules must be PC-4200/5300 compliant.

Memory Module Installation Guidelines

The memory module sockets are arranged in six ranks (1, 2, 3, 4, 5, and 6) on two channels (A and B).

The memory modules ranks are identified as follows:
