Cisco Systems 2500 Series manual Installing Power Requirements and System Identifier Labels

Connecting the DC Power Supply

Warning This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240 VAC, 10A international) is used on the phase conductors (all current-carrying conductors). (To see translated versions of this warning, refer to the Regulatory Compliance and Safety Information document that accompanied the router.)

Warning This equipment is intended to be grounded. Ensure that the host is connected to earth ground during normal use. (To see translated versions of this warning, refer to the Regulatory Compliance and Safety Information document that accompanied the router.)

Installing Power Requirements and System Identifier Labels

Follow the directions in this section to place the Power Requirements and System Identifier labels on the rear panel of the Cisco 2500 series routers.

Note The steps in this section are only performed when the router is being converted from an AC power supply to a DC power supply.

Step 1 Remove the Power Requirements label from the sheet of labels included with the power supply. (See Figure 10.)
