Chassis Description 33
DC Output Current Specifications
The combined output power of all outputs will not exceed 350 W. Each output has a maximum and
minimum current rating shown in Table 10. The power supply meets both static and dynamic
voltage regulation requirements for the minimum dynamic loading conditions. The power supply
meets only the static load voltage regulation requirements for the minimum static load conditions.

Introduction
The AC version of the cc3300 Carrier Grade server uses a -48 to -60 VDC input switching power
subsystem, which provides up to 350 Watts with -48 to -60 VDC input and with current and remote
sense regulation. The power subsystem consists of one or two 350-Watt power supply modules. A
system with two modules forms a redundant, hot-swappable (1+1) power subsystem. There is a
single bi-color LED to indicate power supply status. Refer to Table 11 for conditions of the power
supply LEDs.
