HP Integrity rx2660 Server User Service Guide

3. Complete the following memory installation prerequisite tasks before installing the memory:
a. Determine the DIMM load order. For more information, see “Memory Load Order”
(page 49).
b. To determine which DIMM slots to populate, see Figure 19 (page 49).
c. Read, understand, and follow the general guidelines to install memory in the server.
4. Install each DIMM.
a. Align the DIMM with the slot located on the memory board, and align the key in the
connector with the notch in the DIMM.
b. Firmly and evenly push on each end of the DIMM until it seats into the slot.
c. Ensure the extraction levers are in the fully closed position.
5. Replace the airflow guide if you are finished installing additional components. See “Replacing
the Airflow Guide” (page 55).
6. Replace the top cover if you are finished installing additional components. See “Replacing
the Top Cover” (page 61). Otherwise, continue with installing components.
TIP: If you see abnormal error lights after installing DIMMS, try uninstalling and reinstalling the
DIMMs to make sure the DIMMS are correctly seated.
Installing a Processor
The rx2660 server utilizes single- or dual-core processors. Dual-core processors contain two cores
that function as separate processors. Dual-core processors double the processing power of the
processor while maintaining the physical dimensions of a single processor.
The server holds one or two single- or dual-core processors that provide the following configuration
options:
• 1P/1C (One processor / one core)
• 1P/2C (One processor / two cores)
• 2P/2C (Two processors / two cores)
• 2P/4C (Two processors / four cores)
The server has one processor installed in slot Module 0 before shipping. Install the additional
processor in slot Module 1.
CAUTION: Intel Itanium Dual-Core Intel® Itanium® 2 processors 9150M cannot be intermixed
with similar Dual-Core Intel® Itanium® 2 processors 9000 series. Processor speed and cache size
must be identical for all processors in a system. To ensure compatibility whether upgrading,
replacing, or adding an additional processor, use processors with identical part numbers.
Failure to observe this caution results in performance degradation or system failure.
To ensure compatibility, use processors with identical part numbers.
CAUTION: Observe all ESD safety precautions before attempting this procedure. Failure to follow
ESD safety precautions can result in damage to the server.
Processor Load Order
The server holds up to two single- or dual-core processors on the processor board. The slots on the
processor board are labeled Module 0 and Module 1. If the server has only one processor, it is
installed in slot Module 0. Install the second processor in slot Module 1.
