Network processing
The network processing engine has no external connectors or LEDs. There is a handle for
removing and installing the network processing engine and two captive installation screws
for securing it to the chassis.
The Cisco 7206VXR router comes equipped with one 280W AC-input power supply. (A
280W DC-input power supply option is available.) In Figure 1-4, a Cisco 7206VXR router
is configured with a single AC-input power supply. (A power supply filler plate is installed
over the second power supply bay.) A fully configured Cisco 7206VXR router operates
with only one installed power supply; however, a second, optional power supply of the
same type provides hot-swappable, load-sharing, redundant power.
Note
The power supply has the router's main power switch and either an AC-input power
receptacle or a hardwired DC-input power cable (depending on the type of installed power
supply).
