After you finish
1. Follow the procedure listed in the After working inside your system section.
2. While booting, press F2 to enter System Setup and verify that the processor information
matches the new system configuration.
3. Run the system diagnostics to verify that the new processor operates correctly.
Power supply units
Your system supports the following power supply units (PSUs):
l
450 W AC (non-redundant)
l
550 W AC (redundant)
When two identical PSUs are installed, the power supply 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 power supply configuration is non-redundant (1 + 0). Power is
supplied to the system only by the single PSU.
Note:
If two PSUs are used, they must be of the same type and have the same maximum
output power.
Note: For AC PSUs, use only PSU with the Extended Power Performance (EPP) label on the
back. Mixing PSUs from previous generations of Dell PowerEdge servers can result in a PSU
mismatch condition or failure to turn on.
Hot spare feature
Your system supports the hot spare feature that significantly reduces the power overhead
associated with power supply unit (PSU) redundancy.
