Power supplies
Ten power supply slots that provide AC or DC power to the chassis. A chassis with low line input voltage (90V, 110/120V, 132V) requires a minimum of eight power supplies while a chassis with high line input voltage (180V, 200/240V, 305V) requires a minimum of four power supplies.
The minimum number of power supplies (four for high line and eight for low line) are not enough to establish full power redundancy in a fully loaded chassis.
To provide full redundancy using high line power supplies, you must install eight power supplies. A fully redundant power configuration means that half of the installed power supplies can fail and the appliance and all installed line cards still function.
On the front panel of the chassis, the power supplies are numbered as follows:
