This server is equipped with the defective CPU disconnection function.
This function disconnects the CPU judged to be defective (abnormal) during Power On Self Test
(POST) and start the server. On two-CPU servers, if one CPU is defective, the other CPU starts up the
server.
The failed CPU can be checked with the information displayed during POST or from the [Server] menu
of the BIOS Setup Utility. "
■ CPU Status Submenu" (pg.248)
Replace the defective CPU, if discovered, and then restart the server.
■ Replacing the Defective CPU
Replace the defective CPU with a new one according to "7.3.3 How to Install a CPU" (pg.183).
After replacing the CPU, start the BIOS Setup Utility and select the [Server] menu → the [CPU Status]
submenu to check that [CPU n Status] (n is the number of the replaced CPU) is set to [Enabled]. If the
item is set to [Failed], change the setting to [Enabled]. If it is not set to [Enabled], the server will start
with the CPU recognized as being defective and constantly disconnected. To use the new CPU, set the
item to [Enabled] for releasing the failed CPU status at the next startup.
