Connecting to the PC and powering up
CAUTION
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).
NOTE
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.
