2-26 General Description
CPU/IO Module Status
The CPU/IO module (0 or 1) started first is managed as primary, and the module started later is
managed as secondary. If one CPU/IO module is disconnected because of the failure and others, the
other module becomes primary.
The CPU/IO module to be started first is selected depending on the primary/secondary status of
modules when the server was shut down the last time.
The following devices are connected to the primary CPU/IO module by the hardware switch,
although those can be connected to both CPU/IO modules 0 and 1. When one CPU/IO module is
disconnected because of a failure, those are switched to the other module automatically and
continue operating.
VGA (display)
USB device (keyboard, mouse, Flash FDD)
