Power Supply
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.
