Power Management
The Supervisor module checks the PSU status every three seconds by comparing the
current state to the previously saved PSU state.

The Power Management Process
L The power management process is activated in the SPV only if there is a change
in power requirements or supply caused by one of the following events:
•
Power-up sequence
•
PSU removal if there are two PSUs
•
PSU insertion if there is only one PSU
•
I/O module insertion
•
I/O module removal
•
Administratively enabling/disabling a slot
L Removing both supervisors turns off the entire system.
L In case of power failure in a module, the Supervisor module receives an
indication from the failed module. The Supervisor module will turn off the I/O
module and issues a warning.
