Introduction
If more than one option is being installed, read the installation instructions for all the hardware options
and identify similar steps to streamline the installation process.
WARNING: To reduce the risk of personal injury from hot surfaces, allow the drives and
the internal system components to cool before touching them.
CAUTION: To prevent damage to electrical components, properly ground the server before beginning any
installation procedure. Improper grounding can cause electrostatic discharge.
Memory
You can expand server memory by installing PC2-5300 DDR2 SDRAM DIMMs. The system supports up to
four DIMMs for a maximum of 8 GB.
For DIMM slot locations and bank assignments, see "System board components (on page
10 )."
DIMM installation guidelines
Observe the following guidelines when installing additional memory:
• DIMMs installed in the server must be unbuffered DDR2 DRAM with ECC.
• If only a single DIMM is installed, it must be installed in slot 1A.
• All DIMMs installed must be the same speed.
BIOS detects the DIMM population and sets the system as follows:
• Single-channel mode: DIMMs installed in one channel only.
• Dual-channel asymmetric mode: DIMMs installed in both channels, but of unequal capacities per
channel.
• Dual-channel interleaved mode: DIMMs installed in both channels with equal channel capacities.
