Connecting to the PC and powering up
Ensure AC power is supplied to the PoE power supply using an AC cable with an
appropriate ground connection approved for the country of operation.
To connect the ODU to the PC and power up the unit, proceed as follows:
1
Check that the ODU and PoE power supply are correctly connected.
2
Connect the PC Ethernet port to the DATA IN port of the PoE power supply using
a standard (not crossed) Cat5e cable (Figure 6-3).
3
Connect the PoE power supply to an AC outlet (100 V AC to 240 V AC).
The PoE power supply has no power switch. It supplies power to the ODU as soon
as AC power is applied.
4
Check that the AC and PORT LEDs illuminate (green steady). If they blink or do
not illuminate, refer to Testing link end hardware on
page 8-2.
