2.1.3.2 Remote Power Supply Unit ( RPSU)
There are 2types of RPSU in the HROU for supply to active module in the enclosure and receive power
from external.
They are the DC/DC PSU receiving input -48V and the AC/DC PSU receiving input 110V/220V from
external.
As order, either of the two types should be decided. MS Connector, which uses ports to receive inputs,
is designed to accept any of AC and DC. Only in this case, the input cable is different.
RPSU has a circuit brake to turn the power ON/OFF and has LED indicator at the top to check if input
power is normally supplied.
