or network services engine
The network processing engine or network services engine has no external
connectors or LEDs. There is a handle for removing and installing the network
processing engine or network services 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 Cisco 7206VXR does not support a mixture of AC- and
DC-input power.
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).
