9. Place the processor on the socket such that the slots on the processor align with the socket keys.
10. Close the processor shield.
11. Lower the close first socket-release lever near the lock icon
12. Similarly, lower the open first socket-release lever near the unlock icon

Next steps
NOTE: Ensure that you install the heat sink after you install the processor. The heat sink is necessary
to maintain proper thermal conditions.
1. Install the heat sink.
2. If removed, reinstall the PCIe expansion card riser.
3. If disconnected, reconnect the cables to the expansion cards.
4. While booting, press F2 to enter System Setup and verify that the processor information matches the
new system configuration.

Power supply units

Your system supports 350 W AC redundant power supply units (PSUs).
NOTE: If two PSUs are used, they must be of the same type and have the same maximum output
power.
When two identical PSUs are installed, the PSU configuration is redundant (1 + 1). In redundant mode,
power is supplied to the system equally from both PSUs to maximize efficiency.
When only one PSU is installed, the PSU configuration is non-redundant (1 + 0). Power is supplied to the
system only by the single PSU.
In a non-redundant configuration, install a PSU blank in the empty PSU slot.

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, one of the redundant PSUs is switched to the sleep state. The
active PSU supports 100 percent of the load, thus operating at higher efficiency. The PSU in the sleep
state monitors output voltage of the active PSU. If the output voltage of the active PSU drops, the PSU in
the sleep state returns to an active output state.
