Power over Ethernet Switches (PoE)
When considering the use of Power over Ethernet (PoE) data switches in your network, keep in mind
that not all PoE data switches provide power to all data ports, and not all PoE data switches provide
adequate power to support all devices.
For example, when 24 IP560 phones are plugged into a switch, the maximum power requirement can
reach 153.6 W (24 phones x 6.4W/phone).
 The value in the Maximum column in Table 13 is normally a spike – typically during bootup.
During normal operation, phones require less power.
 Verify that power allocated to the PoE ports matches the switch wattage.
 ShoreTel recommends selecting a PoE data switch that includes four hardware queues for Quality
of Service (QoS) to ensure that rules can be set up to ensure adequate bandwidth for VoIP and
other critical traffic.
