microprocessors are installed and microprocessor 1 fails, the server will switch to
microprocessor 2 until the server is serviced. To ensure that the microprocessor
failover support works correctly, do the following:
– Make sure that microprocessor 1 and microprocessor 2 have valid boot
devices and paths. That is, an Ethernet controller or a SAS controller must be
installed in slots 1, 2, 3, 4, or 5 to boot from microprocessor 2.
– Make sure that the boot order in the Setup utility is set up so that both
microprocessor 1 and microprocessor 2 boot devices are in the boot order.

the heat sink or set down the heat sink. For more information, see "Thermal
grease" on page 101.
Note: Removing the heat sink from the microprocessor destroys the even
distribution of the thermal grease and requires replacing the thermal grease.
