If a link is not established and it is connected to a PD device, check the PoE Port
Status to ensure that there is 48 Vdc power at the 4H4285‐49 RJ45 port. Refer to

Verifying PoE Port Status
If a PD is connected to the 4H4285‐49 RJ45 port, ensure that there is power at the RJ45 port
as follows:
1.
Press on the GROUP SELECT button for more than one second. The 4H4285‐49 will
enter the PoE status mode, which will indicate a set of power status conditions
relating to the PoE Port Status.
2.
Now, every time you press the GROUP SELECT button for less than a second, the
GROUP LED lights up in sequence, indicating which Group is selected. The PoE
POWER STATUS for that group of segments is then indicated by the RX and TX LEDs
for each segment. If there is power at the port, the RX LED is green and the TX LED is
off. Otherwise, refer to
for troubleshooting information.
