Introduction
The DC 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.
Interface Requirements
DC Input
The DC power source may produce hazardous voltage levels exceeding -60 VDC and high energy
levels above 240VA that may cause electric shock or burns. All DC input connections should be
