AC power input is provided by 4 IEC 320

C20 connectors at the rear side 

of the Shelf. 

The Power Distribution Board (PDB) is located behind the AC PSUs. It 
provides 4 connectors for the PSUs and a connector for the PMbus 
interface to the CAN to I2C bridge function modular. 

 

 

6.5  PMBus Interface 

 

The Huawei R4850xx series PSU only support communication on the 
CAN bus, there is a function modular to implement the bridge from CAN 
bus to I2C bus on the Power Distribution Board. The PMBus is routed 
from the CAN to I2C bus bridge to the local I2C bus of the fan tray, so that 
the PSUs can be managed by the IPM controller of the fan tray.
