2.The Cisco 7513 requires a minimum of 20-amp service, with a 20-amp receptacle at the power source. The power cable supplied with the Cisco 7513 uses a 20-amp male plug.
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 supplies provide system power simultaneously (load share). When you remove one supply, the remaining supply immediately ramps up to provide full power and maintain uninterrupted power to the system. Whenever possible, connect each power supply to a separate AC source.
Caution The new and older power supplies must not be used simultaneously in the Cisco 7513. The redundant power, load-sharing feature of the Cisco 7513 requires identical power supplies in each of the two power supply bays. While no physical damage will occur if the two different supplies are installed into a Cisco 7513, there is the possibility of erratic system behavior and error messages.
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 power supplies are self-monitoring. Each supply monitors its own temperature and internal voltages. An internal fan in each power supply draws cooling air from the rear of the chassis, through the power supply, and out the front of the chassis. The power supply airflow is separate from that of the rest of the chassis.
The Cisco 7513 requires a minimum of 20-amp service, with a 20-amp receptacle at the power source. The power cable supplied with the Cisco 7513 uses a 20-amp male plug. shows the cable connector plug and the 20-amp receptacle required to connect the 20-amp cable to your AC source.
Note Wiring codes prevent this type of power cable from being used with the power strips in equipment racks.
