3.3.2 PIDU Plus – PTP 300/500/600 Series Bridge
The PTP 300/500/600 Series Bridge PIDU Plus is used to generate the ODU supply voltage
from the mains supply and inject this supply voltage into the 100BaseT Ethernet connection
to the ODU. Connection uses a CAT5e cable using standard RJ45 wiring.
CAUTION Care should be taken not to connect equipment other than an ODU for the PTP
500 Series Bridge to a PIDU Plus ODU port as equipment damage may occur. The PTP
300/500/600 Series Bridge PIDU Plus is not interchangeable with the PTP 400 Series PIDU
Plus.

The front panel contains indicators showing the status of the power and Ethernet
connections.
The power indicator is illuminated when the PIDU Plus is receiving mains power.
The Ethernet indicator normally illuminates when the Ethernet link is working, flashing when
there is Ethernet activity. The fact that it lights also indicates that the ODU is powered. At
power up the LED will flash 10 times to indicate that a correct start up sequence has
occurred. See Section 10 “Fault Finding” for further fault finding information.
At the bottom of the PIDU Plus is an entry point for the PIDU Plus to ODU cable, the
100BaseT Ethernet network port and the Recovery switch.
