6.With the release levers on the processor socket in the open position, align pin 1 of the processor, using pin 1 position guide on the socket, as reference and set the processor lightly in the socket.
CAUTION: Do not use force to seat the processor. When the processor is positioned correctly, it engages easily into the socket.
7.Close the processor shield.
8.Rotate the 
until it is locked in position.
9.Similarly, rotate the 
until it is locked in position.
10.Using a clean
CAUTION: Applying too much thermal grease can result in excess grease coming in contact with and contaminating the processor socket.
11.Open the grease applicator included with your processor kit and apply all of the thermal grease in the applicator to the center of the topside of the new processor.
12.Place the heat sink on the processor. Ensure the beveled side of the heatsink is toward the lock icon 
on the processor.
13.Using a #2 Phillips screwdriver, tighten the
14.If applicable, install the cooling shroud or the processor expansion module.
15.Close the system.
16.Reconnect your system and peripherals to their electrical outlets, and turn on the system.
17.Press <F2> to enter the System Setup and check that the processor information matches the new system configuration.
18.Run the system diagnostics to verify that the new processor operates correctly. See Using System Diagnostics for available diagnostic tests.
Power Supplies
Your system supports either:
•Two 750 W or 1100 W AC power supply modules
•Two 750 W Titanium efficiency power supply modules
•Two 1100 W DC power supply modules
NOTE: Titanium power supply is nominally rated for 200 VAC to 240 VAC input only.
NOTE: When two identical power supplies are installed, power supply redundancy (1+1 – with redundancy or 2+0
–without redundancy) is configured in system BIOS. In redundant mode, power is supplied to the system equally from both power supplies when Hot Spare is disabled. When Hot Spare is enabled, one of the PSUs will be put into standby when system utilization is low in order to maximize efficiency.
When only one power supply is installed, the power supply configuration is
NOTE: If two power supplies are used, they must be of the same type and have the same maximum output power.
Hot Spare Feature
Your system supports the Hot Spare feature that significantly reduces the power overhead associated with power supply redundancy.
When the Hot Spare feature is enabled, a redundant power supply is switched to a sleep state. The active power supply supports 100% of the load, thus operating at higher efficiency. The redundant power supply in the sleep state monitors
