Chapter 1 Cisco 7200 VXR Product Overview Field-Replaceable Units Power Supplies The Cisco 7200 VXR routers come equipped with one 280W AC-input power supply. (A 280W DC-input power supply is available as an option.) You must order the second power supply separately. A second power supply, although not required, allows load sharing and increased system availability. Note The Cisco 7200 VXR power supplies are the same as in all Cisco 7200 series routers. Caution The DC return connection to this system is to remain isolated from the system frame and chassis (DC-I). Caution Do not mix power supplies in Cisco 7200 VXR routers. In dual power supply configurations, both power supplies must be of the same type (two AC-input power supplies or two DC-input power supplies). Note Detailed instructions for handling and replacing the Cisco 7200 series power supplies are contained in the configuration notes 280-Watt AC-Input Power Supply Replacement Instructions and 280-Watt DC-Input Power Supply Replacement Instructions. These configuration notes are available on the Documentation DVD and on Cisco.com. A handle on the AC and DC power supplies provides a grip point for removing and replacing the power supply. (Figure 1-28 shows the faceplate of the AC-input power supply. Figure 1-29 shows the faceplate of the DC-input power supply.) Two captive installation screws secure the power supply to the chassis and seat the power supply in the router midplane. A power OK LED indicates that the power supply is delivering +5 VDC to the router midplane. OL-5013-09 Cisco 7200 VXR Installation and Configuration Guide 1-49
