Power Supp lies

The Cisco 7206 router is equipped with one 280W AC-input or one 280W DC-input power supply.

A fully configured Cisco 7206 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. Figure1-21 shows the rear of a Cisco 7206 router configured with a single AC-input power

supply. (A power supply filler plate is installed over the second power supply bay.)

Caution Do not mix power supplies in the Cisco 7206. In dual power supply router configurati ons,

both power supplies must be of the same type (two AC-input power supplies or two DC-input po wer

supplies).

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 ). The rear of the

Cisco 7206 router provides access to the network processing engine and the power supplies.

Adjacent to the power supply bays are two chassis ground receptacles tha t pro vide a chas sis grou nd

connection for ESD equipment or a two-hole grounding lug. (See Figure1-21.)
