Converters."
11. If you removed any DIMMs replace them as described in "Installing DIMMs".
Replace the Processor/Memory Complex.

Installing and Removing DIMMs

The BIOS automatically detects, sizes, and initializes the memory array, depending on the type, size, and
speed of the installed DIMMs. It reports the memory size and allocation to the system through the
configuration registers. DIMMs reside in the Processor/Memory Complex and are accessible inside the
server chassis. To remove or install DIMMs you need to access the complex and follow the installation order
and groupings required for the DIMMs. It is not necessary to remove the memory board from the complex.

Memory Guidelines

Each Memory Board can support from 1 GB to 32 GB. The server supports up to 64 GB of system memory.
•
Use only HP DIMMs, which are 3.3V, 168-pin, PC100, buffered SDRAM DIMMs in 256 MB, 512
MB, or 1 GB modules.
•
DIMMs must be installed in the order indicated by the numbered slots on the memory board in
groups of four. Verify that the same size DIMM is used in any given row by using the same HP
part number.
•
To ensure optimum performance when two boards are installed, the memory on each board
must be equal, that is, the DIMMs must be the same type and quantity.
•
Ensure both latches close on the DIMM when completely installed.
•
When handling DIMMs, observe anti-static precautions to avoid damage.

Installing DIMMs

To install DIMMs, complete the following procedure:
CAUTION
1. If the system is already installed and working, power down the system.
WARNING
2. Disconnect the power cables and all external cables.
If necessary, label each one to aid in the re-assembly of the unit.
3. Remove the top cover from the HP Server.
4. Observe safety and ESD precautions when working with DIMMs.
The memory modules are sensitive to static electricity and can be easily damaged
by improper handling. Do the following when handling the accessory kit:
•
Leave the memory module in the anti-static container until you are ready to install
it.
•
Always use an anti-static wrist strap and a grounding mat.
•
Before you remove a memory module from the anti-static container, touch a
grounded, unpainted metal surface on the HP Server to discharge static
electricity.
The power supply will continue to provide standby current to the HP Server until the
power cable is disconnected.
