The Cisco 7609 Internet Router supports redundant AC-input and DC-input
power supplies.
Each power supply has an individual power switch.
The AC-input power supply (see Figure 1-3) has a detachable power cord (except
for the WS-CAC-4000W) that allows you to connect each power supply to the site
power source. You can connect the DC-input power supply (see Figure 1-4) to the
power source with heavy gauge wiring connected to a terminal block.
Note The power cord is not shown in Figure1-3.
Both AC-input and DC-input power supplies support redundancy. When power is
removed from one supply, the redundant power feature causes the second supply
to produce full power.
Note If you run the 2500W power supply at the low range input (100 to 120 VAC),
it is not redundant in a fully populated Cisco 7609 Internet Router.
For complete power specifications, see AppendixA, “Technical Specifications.”
