1200-Watt AC-Input Power Supply Replacement Instructions  3

Power bay A contains the first (or standard) power supply, and power bay B contains the second
(optional) supply in systems with redundant power. Table 1 lists the AC-input power supply
specifications.

The Cisco 7576 features two routers on one backplane. These are identified as router A and

router B. These designations have no relationship to the power bays, which are identified as
power A and power B.

AC-Input Power Supply Specifications

Table 1 lists the AC-input power supply specifications.

Dual power supplies are automatically load sharing and redundant, which means that you can install
or replace a second power supply on line. During normal operation, dual power supplies provide
system power simultaneously (load share). When you remove one power supply, the remaining
power supply immediately powers up to provide full power and maintain uninterrupted power to the
system. Whenever possible, connect each power supply to a separate AC source.

The AC-input power supply uses a power factor corrector (PFC) that automatically adjusts for the
input voltage being supplied. The AC-input voltage range is 100 to 240 VAC.

The Cisco 7513 and Cisco 7576 require a minimum of 20-Amp service with a 20-Amp receptacle at
the power source. The power cable supplied with the Cisco 7513 and Cisco 7576 uses a 20-Amp
male plug. Figure 2 shows the cable connector plug and the 20-Amp receptacle required to connect
the 20-amp cable to your AC source.

Wiring codes prevent the type of power cables shown in Figure 2 from being used with the

power strips in equipment racks.
