Cisco 7204VXR Overview
Figure 1-2 Cisco 7204VXR Router—Rear View
The network processing engines NPE-100 through NPE-400 or network services engine (NSE-1) have
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 NPE-G1 has external connectors and LEDs for the Gigabit Ethernet interfaces as well as console
and auxiliary ports.
The Cisco 7204VXR router comes equipped with one 280W AC-input power supply. (A 280W DC-input
power supply option is available.) In Figure 1-2, a Cisco 7204VXR 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 7204VXR 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 7204VXR 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).
Caution Do not mix power supplies in the Cisco 7204VXR. In dual power supply router configurations, both
power supplies must be of the same type (two AC-input power supplies or two DC-input power supplies).
Adjacent to the power supply bays are two chassis grounding receptacles that provide a chassis ground
connection for ESD equipment or a two-hole grounding lug. (See Figure 1-2.)
