For client devices (access switches), Dell™ Networking 7048P Power over Ethernet can be used. These
switches provide 30.8 watts per port for Lync clients, including the Polycom CX600 IP phones, and
eliminate the need for an external power source.
4.2.3 Wireless Networking
For Lync 2013 real-time workloads, Dell recommends the Dell Networking W-Series wireless controllers
and access points (PowerConnect W). The W-Series 3200 controller can support up to 2,048 users and
can manage 32 LAN access points and 128 remote access points (APs). The access point chosen for this
configuration is W-AP135, which can deliver wireline-like data rates of up to 450 Mbps. This translates to a
capability to handle numerous audio-video sessions simultaneously, assuming each audio stream is 65
Kbps and each video stream is 500 Kbps. It should be noted though that the performance and quality of
experience of Lync Server must be monitored, and these throughput values should not be used as the only
metric to assess quality of experience.
