Cisco 7200 VXR Product Overview
The DC-input power supply has DC-input power leads that are hardwired to a DC-input terminal block.
A cable tie is shipped with each DC-input power supply to secure the leads to the power supply faceplate
and provide strain relief for the leads.

service. Each DC-input power supply operating at –48 VDC in North America requires a minimum of
13A service. Each DC-input power supply operating at –60 VDC in the European Community requires
a minimum of 8A service.
This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that a
listed and certified fuse or circuit breaker, 20A 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.
The power OK LED goes off and the power supply shuts itself down when the internal DC voltages
exceed allowable tolerances or the internal temperature of the power supply exceeds allowable
tolerances. The power supply remains in a shutdown state until it is disconnected and reconnected to the
source power, and then restarted with the power switch. The power switch turns the power supply on and
starts the system. For a description of power supply shutdown conditions and thresholds, see the
"Environmental Monitoring and Reporting Functions" section on page
Chassis

(depending on your chassis model), one slot for the I/O controller, and one bay for the subchassis. The
subchassis assembly contains the midplane, the fan tray, two power supply bays, and one slot for the
network processing engine. The replacement chassis includes the subchassis assembly and one power
supply.
To replace the chassis, you must remove and replace all the port adapters, the I/O controller, and the
