PIDU Plus PTP 300/500/600 Series

The PIDU Plus PTP 300/500/600 Series (Figure 3) is used to generate the ODU supply
voltage from the mains supply (or from an external DC source) 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 or LPU for the
PTP 500 Series Bridge to a PIDU Plus ODU port, as equipment damage may occur.
The PIDU Plus PTP 300/500/600 Series is not interchangeable with the PIDU Plus
PTP 400 Series.

2.7.1 Power and Ethernet LEDs

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 9 "Fault Finding" for further fault finding information.
