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 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 accompany every 280W AC-input power supply
and every 280W DC-input power supply that is shipped from the
factory as a FRU. These configuration notes are also available on the
Documentation CD-ROM and on CCO.
A handle on the AC and DC power supplies provides a grip point for removing
and replacing the power supply. (Figure 1-23 shows the faceplate of the AC-input
power supply. Figure 1-24 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.
