NOTE
The PSU(s) do not supply power to the AU-ODUs that are powered directly from the
power source via the PIU and the back plane.
Power Interface Unit (PIU)
The single Euro PIU module is the interface between the Base Station
site's DC power source and the Base Station Chassis Power Supply
Units and external ODUs, which receive power via the IDUs.
The PIU filters and stabilizes the Base Station input power and protects
the system from power problems such as over voltage, surge pulses,
reverse polarity connection and short circuits. It also filters high
frequency interference (radiated emissions) and low frequency
interference (conducted emissions) to the external power source. Each
Base Station chassis contains two slots for an optional 1+1 PIU
redundancy. One PIU is sufficient to support a fully populated chassis.
Two PIU modules provide redundant power feeding (two input sources)
while avoiding current flow between the two input sources.
