Device Hardware Support
Topic Last Modified: 2012-06-21
Specific hardware configurations must be in place before you deploy IP phones and analog devices.
IP phones running Lync Phone Edition support Link Layer Discovery Protocol-Media Endpoint Discovery (LLDP-MED) and Power over Ethernet (PoE). To take advantage of LLDP-MED, the switch must support IEEE802.1AB and ANSI/TIA-1057. To take advantage of PoE, the switch must support PoE802.3AF or 802.3at.
To enable LLDP-MED, the administrator must enable LLDP by using the switch console window and set the LLDP-MED network policy with the correct voice VLAN ID.
In addition, if your deployment includes analog devices, you must configure the analog gateway to use Lync Server, and the gateway must be one of the following:
An analog telephone adapter (ATA)
A PSTN analog gateway
A Survivable Branch Appliance that includes a PSTN analog gateway
A Survivable Branch Appliance that includes a PSTN gateway that communicates with an ATA
To learn how to configure an analog gateway, see Planning to Deploy Analog Devices in the Planning documentation.
You can configure the switch for Enhanced 9-1-1 (E9-1-1), if the switch supports this.
