DATA CENTER and CAMPUS NETWORKS DEPLOYMENT GUIDE
Deploying Brocade Networks with Microsoft Lync Server 2010 28 of 52
The minimum configuration for active-active is VIP. Configure the VIP to use sym-active:
Hardware load balance (config)# server virtual vip1 1.1.1.1
Hardware load balance (config)# Port 80
Hardware load balance (config)# sym-priority 10
Hardware load balance (config)#sym-active
Configuring PoE for the Campus Network
Power over Ethernet is a core component for Unified Communications. Microsoft Lync Server 2010 endpoints do not
require PoE unless you are using IP phones, such as the Polycom CX700 IP phone. Polycom extends this Microsoft
Lync Server 2010 user experience with a broad portfolio of high-definition voice and video endpoints, including the
CX family of phones, the HDX family of video conferencing systems, and the RPX and TPX telepresence suites.
Brocade PoE devices provide Power over Ethernet, which is compliant with the standards described in the IEEE
802.3af specification for delivering in-line power. The 802.3af specification defines the standard for delivering power
over existing network cabling infrastructure and enabling multicast-enabled full streaming audio and video
applications for converged services, such as VoIP, WLAN access points, IP surveillance cameras, and other IP
technology devices. PoE technology eliminates the need for an electrical outlet and dedicated UPS near IP-powered
devices. With power sourcing devices such as the Brocade FastIron
®
CX, power is consolidated and centralized in
wiring closets, improving the reliability and resiliency of the network. Because PoE can provide power over an
Ethernet cable, power is continuous, even if the main power source fails.
To enable a port to receive in-line power for 802.3af-compliant and non-compliant power consuming devices, enter
commands such as the following:
FastIron#config t
FastIron(config)#interface e 1/1
FastIron(config-if-e1000-1/1)#inline power
After these commands are run, the console displays the following message:
FastIron(config-if-e1000-1/1)#PoE Info: Power enabled on port 1/1.
When PoE is enabled on a port to which a power-consuming device is attached, then by default the Brocade
PoE device supplies 15.4 watts of power at the RJ45 jack, minus any power loss through the cables. For example, a
PoE port with a default maximum power level of 15.4 watts receives a maximum of 12.95 watts of power after 2.45
watts of power loss through the cable.
NOTE: It is best practice to enable PoE on all ports.
