After connecting the speaker to the 802.3af compliant Ethernet hub, the LEDs on the speaker face
confirm that the speaker is operational and linked to the network.
Figure 2-9. Status and Activity LEDs
2.2.3.1 Status LED
After supplying power to the speaker:
1. The green power/status LED and the yellow network LED comes on immediately.
2. After about 23 seconds with a static IP address (or 27 seconds if the board is set to use DHCP),
the green LED will blink twice to indicate that the board is fully booted.
Note If the board is set to use DHCP and there is not a DHCP server available on the network, it
will try five times with a three second delay between tries and eventually fall back to the
programmed static IP address (by default 10.10.10.10). This process will take approximately
80 seconds.
2.2.3.2 Link LED
● The Link LED is illuminated when the network link to the speaker is established.
● The Link LED blinks to indicate network traffic.
