Figure 2 45 Mbps Backhaul Power Indoor Unit (PIDU)
The front panel contains indicators showing the status of the power and Ethernet connections.
The power indicator is illuminated when the PIDU is receiving AC (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 7 for further fault finding information.
The bottom of the PIDU houses the Ethernet connection via RJ-45 socket, an entry point for PIDU/ODU
cabling and the reset button.
