If the server has fewer than the maximum number of dual-core processors installed, install the
additional processor in the appropriate slot.
WARNING! Ensure that the system is powered off and all power sources have been disconnected
from the server prior to performing this procedure.
Voltages are present at various locations within the server whenever an ac power source is
connected. This voltage is present even when the main power switch is in the off position.
Failure to observe this warning can result in personal injury or damage to equipment.
CAUTION: Intel Montvale processors cannot be intermixed with similar Montecito processors.
Processor speed and cache size must be identical for all processors in a system. Whether
upgrading, replacing or adding an additional processor, to ensure compatibility use processors
with identical part numbers.
Failure to observe this caution results in performance degradation or system failure.
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 can have up to two dual-core processors on the processor board. The slots on the
processor board are labeled Module 0 and Module 1.
Table 6-8 lists the processor load sequence.

Required Tools
To install and remove processors, use the processor install tool fastened to the processor board.
Removing a Dual-Core Processor
To remove a dual-core processor, follow these steps:
1. Power off the server and disconnect the power cables. See “Powering Off the Server”
(page 95).
2. If rack installed, slide the server out from the rack until it stops. See “Extending the Server
from the Rack” (page 180).
3. Remove the memory carrier assembly cover. See “Removing the Memory Carrier Assembly
Cover” (page 183).
NOTE: You do not need to fully remove the top cover to service this component; however,
the top cover release lever must be open. You must remove the memory carrier because it
attaches directly to the processor board.
4. Remove the memory carrier assembly. See “Removing the Memory Carrier Assembly”
(page 204).
5. Remove the processor board assembly. See “Removing the Processor Board Assembly”
(page 217).
