The 4500 can utilize two power supplies to work in either combined or redundant
mode
Redundant Mode Combined Mode
In redundant mode, each power supply
operates at 50% capacity and provides the
same total power as a single power supply
– if one fails, the backup reverts to
providing 100% power
In combined mode, each power supply
operates at 83% - if one fails, then the
running supply provides 100% of its power
capacity
