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 back panel of the chassis, the power supplies are numbered as
follows:
