Power Management

The Supervisor module checks the PSU status every three seconds by comparing the
current state to the previously saved PSU state.
Figure 4.2

The Power Management Process

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
Removing both supervisors turns off the entire system.
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.
