3.3.2 PIDU Plus – PTP 500 Series Bridge
The PTP 500 Series Bridge PIDU Plus is used to generate the ODU supply voltage from the
mains supply and inject this supply voltage into the 1000BaseT 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 500 Series
Bridge PIDU Plus is not interchangeable with the PTP 400 Series PIDU Plus but can be used
with the PTP 600 Series.

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.
