DC Input Distributed Power Front-End
Emerson Network Power produces five series of DC-input bulk front-end power modules for systems that use distributed power architectures.
The DC-input DS series power modules are compact, high efficiency units with a 1U x 2U form factor. The modules have power output ratings from 450 watts up to 1200 watts.
Each power module contains a serial EEPROM (electrically erasable programmable read-only memory) that is preprogrammed with data about the unit – including its type, serial number and date of manufacture – to facilitate replacement in the field. A built-in I2C interface, which uses the PMBus™ protocol, enables the data to be read back to the system under power; the interface also allows the system to interrogate the power module to ascertain various operational parameters, including input and output status, fan blocked or running under-speed, and overcurrent and overtemperature flags.
All DC-input modules offered by Emerson Network Power provide a very flexible and cost-effective menas of accomodating the high bulk power demands of today's networking equipment.
