The Switch 8800 power supplies are installed at the bottom of the chassis, in the
front. Only one AC power supply is required for each Switch 8800 chassis,
although 2 power supply slots are provided to implement 1+1 redundancy.
The 7-slot chassis uses a 1200 W auto-ranging power supply (3C17506).
The 10- and 14-slot chassis use a 2000 W auto-ranging power supply (3C17507).
When this power supply is used at 110 V, it delivers 1200 W of power, when used
at 220 V, it delivers 2000 W of power.
Do not combine 1200 W and 2000 W power supplies in the same chassis. If you
have two power supplies in your Switch 8800 chassis, they must be of the same
type.
Figure 7 illustrates the 1200 W power supply for the Switch 8800.
