Step 9 Restore current to the –V and +V leads.

Note For the Cisco uBR7200 series routers, each DC-input power supply rating is 14A, 700 volt ampere (VA).

This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that a listed and certified fuse or circuit breaker, 35A minimum 60 VDC, is used on all current-carrying conductors. Site wiring and circuit breakers need to be sized to accommodate the maximum values for safety reasons.

Step 10 Repeat Step 1 through Step 9 if a second power supply is installed.

This completes the steps for reconnecting DC-input power to a Cisco uBR7246VXR router. Proceed to the following section, “Powering Up the Router.”
