Field-Replaceable Units
Each DC-input power supply operating at –48 VDC in North America requires a minimum of 13A
Note
service. Each DC-input power supply operating at –60 VDC in the European Union 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.
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, refer to the
"Environmental Monitoring and Reporting Functions" section on page
