Installing the VoIP SIP/Multicast Wall Mount Speaker 11Device Configuration2.2.2 Confirm that the Speaker is Operational and Linked to the NetworkAfter connecting the speaker to the 802.3af compliant Ethernet hub, the LEDs on the speaker faceconfirm that the speaker is operational and linked to the network.Figure 2-3. Status and Activity LEDsNetwork100 Mb(Yellow)SpeakerLink/Activity(Green)2.2.2.1 Link/Activity LEDAfter supplying power to the speaker:1. The green Link/Activity LED comes on immediately to show that there is a good networkconnection, and then blinks to show network activity.2. After about 23 seconds with a static IP address (or 27 seconds if the board is set to use DHCP),the speaker should be ready.NoteIf the board is set to use DHCP and there is not a DHCP server available on the network, itwill try 12 times with a three second delay between tries and eventually fall back to theprogrammed static IP address (by default IPv4 Link Local). This process will takeapproximately 80 seconds.2.2.2.2 100 Mb LED Operations GuideThe yellow 100 Mb LED is illuminated when the network 100 Mb link to the speaker isestablished.931908ACyberData Corporation
