Before you configure PoE, be sure you have:
•
Performed the initial switch configuration. See “Connecting and Configuring an EX
Series Switch (CLI Procedure)” on page 187 or “Connecting and Configuring an EX Series
Switch (J-Web Procedure)” on page 189 for details.
Overview and Topology
The topology used in this example consists of a switch that has 24 ports. Eight of the
ports support PoE (IEEE 802.3af), which means they provide both network connectivity
and electric power for powered devices such as VoIP telephones, wireless access points,
and IP security cameras that require 12.95 W or less. The remaining 16 ports provide only
network connectivity. You use the standard ports to connect devices that have their own
power sources, such as desktop and laptop computers, printers, and servers. Table 441
on page 3310 details the topology used in this configuration example.

Configuration
To configure PoE interfaces:
CLI Quick
Configuration
By default, PoE interfaces are created for all PoE ports and PoE is enabled. The default
priority for PoE interfaces is
low
.
To quickly set some interfaces to high priority and to include descriptions of the interfaces,
copy the following commands and paste them into the switch terminal window:
[edit]
set poe interface ge-0/0/1 priority high telemetries
set poe interface ge-0/0/2 priority high telemetries
