Status indication
There are nine LED indicators on the front panel to provide router status information. Each
ETH port has two additional LEDs that provide information about the port status.

Table 8: Status indication
* Additionally it can indicate a device without PoE support connected on the other side of the
cable. In this case the indication is caused by low impedance (lower than 500
Ω
) of the device
without PoE support. This can be solved by disabling the PoE PSE feature on the relevant
ETH port in the router’s Web interface, see
Configuration manual
The status indication of the WAN LED is updated every 10 seconds.
