Power Sources for Redundant Power Supplies Warning for EX4200 Switches
EX4200 switches have a redundant power supply. When you have redundant power
supplies in a switch, you must connect each power supply to a different input power
source. Failure to do so makes the switch susceptible to total power failure if one of
the power supplies fails.
