Different Power Ratings
If using dual power supplies with different power ratings (wattage), the higher wattage supply must be set as the
primary supply (PS2) and must be set at least 2V above the backup or lower wattage supply (PS1). Most or all of
the power will be sourced from the primary supply.
In the case of failure of the primary power supply, the switch will start drawing power from the backup supply and
the new backup power budget will be evaluated by the switch. If the budget is in violation, the ports will be
powered down by priority (low then high then critical priority) until the power budget is no longer in violation.
Within each priority, ports will be powered down in order from lowest to highest port number. When the primary
power source is restored, the primary power budget will go back into effect and any previously powered down
ports will be restored if not in violation of the primary power budget.
