AC-Input Power Supply Overview
AC-Input Power Supply Overview
A fully configured Cisco 7200 series router comes equipped with one 280W, AC-input power
supply. An optional, second AC-input power supply is available for the router; it must be ordered.
The router operates with one installed power supply; however, the second power supply provides
hot-swappable, load-sharing redundant power.
The faceplate of the 280W AC-input power supply has a green OK LED, a power switch, a handle
for removing, installing, and handling the power supply, an AC-input power receptacle, and two
captive installation screws (refer to Figure 1).

The AC-input power supply operates between 100 and 240 VAC input voltage and supplies +5V,
+12V, –12V, and +3V DC power to the router’s internal components through the router midplane.
Note Each AC-input power supply operating at 120 VAC requires a minimum of 5A service. We
recommend powering Cisco 7200 series routers from a 120 VAC, 15A receptacle U.S. (240 VAC,
10A international) at the power source.
The power supply handle provides a grip point for pulling the power supply out of the router (refer
to Figure 1). The two captive installation screws secure the power supply in the router. A modular
power cable connects the AC-input power supply to the site AC power source.
A cable-retention clip on the power supply secures the cable in the power supply and provides strain
relief for the power cable. The power switch turns the power supply on and starts the system.

in a rack, or if you already have clear access to the rear of the router, proceed to the following section
“Removing and Replacing the AC-Input Power Supply.”
Use the following guidelines to ensure easy access to the rear of the router when it is installed in a
rack:
•
•
Ensure that you have at least three to four feet of working space at the rear of the router.
•
If access to the rear of the router is partially blocked by a power strip or some other permanent
rack fixture, detach the router from the rack and carefully slide it forward until there is enough
clearance to remove the power supply, the network processing engine, and the subchassis from
the router. Detailed steps for detaching the router from the rack are contained in the following
section “Removing and Replacing the AC-Input Power Supply.”
If cables from other equipment in the rack fall in front of the rear end of the router, carefully
gather the cables (using care not to strain them) and use cable ties to anchor them away from the
rear of the router.
Caution Make sure that at least one other person is available to support the front of the router as
you slide it out from the rack and, if necessary, to continue to support it while you remove and insert
the power supply, network processing engine, or subchassis.

simultaneously: a character-based version and a multimedia version that resides on the World Wide

e-mail, and it is excellent for quick access to information over lower bandwidths. The WWW version
of CCO provides richly formatted documents with photographs, figures, graphics, and video, as well
as hyperlinks to related information.
