Unpack the drive and prepare it for installation. For instructions, see the documentation that
accompanied the drive.
If you are installing a SCSI tape drive, you must have a SCSI controller card installed (see "Installing an Expansion Card" on page 57) and configure the tape drive according to the documentation that came with the tape drive, based on the following guidelines:
Each device attached to a SCSI host adapter must have a unique SCSI ID number (narrow SCSI
devices use IDs 0 to 7; wide SCSI devices use IDs from 0 to 15). Set the drive's SCSI ID to avoid
conflicts with other devices on the SCSI bus. For the default SCSI ID setting, see the
documentation provided with the drive.
NOTE: There is no requirement that SCSI ID numbers be assigned sequentially or that devices be attached to the cable in order by ID number.
SCSI logic requires that the two devices at opposite ends of a SCSI chain be terminated and that
all devices in between be unterminated. Therefore, you enable the tape drive's termination if it is
the last device in a chain of devices (or sole device) connected to the SCSI controller.
Turn off the system, including any attached peripherals, and disconnect the system from the electrical
outlet.
Remove the three shoulder screws from the insert, and attach them to the bottom row of holes on the

Memory Module Upgrade Kits
The system is upgradable to 4 GB by installing combinations of 512-MB and 1-GB 533-MHz or 667-MHz unbuffered ECC DDR II single or dual-rank memory modules. You can purchase memory upgrade kits from Dell.
Memory Module Installation Guidelines
If only one memory module is installed, it must be installed in connector DIMM_1.
If only one memory module is installed in connector DIMM_1, its capacity must be 512 MB.
If more than one memory module is installed, the memory modules must be installed in pairs of matched memory size, speed, and technology.
Memory modules must be installed in ordered pairs in connectors DIMM_1 and DIMM_2, and then DIMM_3 and DIMM_4.
If a processor with a slower front-side bus rating than the memory is installed, the memory will operate at the processor's slower front-side bus speed.
NOTICE: If you remove your original memory modules from the system during a memory upgrade, keep them separate from any new memory modules that you may have, even if you purchased the new memory modules from Dell. Use only unregistered or unbuffered ECC DDR II memory modules.

Addressing Memory With 4-GB Configurations (Microsoft® Windows® Operating System Only)
Your system supports a maximum of 4 GB of memory using four 1-GB memory modules. Current operating systems can use a maximum of 4 GB of address space; however, the amount of memory available to the operating system is slightly less than 4 GB.
NOTE: Depending on the type of PCI/PCIe expansion cards that are installed in your system, your system may only support a maximum of 3.4 GB of memory or less.
Integrated PCI devices (such as NICs) and SCSI controllers
PCI expansion cards
At start-up, the BIOS identifies the components that require address space. The BIOS dynamically calculates the amount of reserved address space required. The BIOS then subtracts the reserved address space from 4 GB to determine the amount of usable space.
If the total installed system memory is less than the usable space, all installed system memory is available for use only by the operating system.
If the total installed system memory is equal to or greater than the usable address space, a small portion of installed memory is available for use by the operating system.
