OS for EX Series Ethernet Switches, Release 10.3
Each EX2200 switch has four uplink ports that support 1-gigabit small form-factor
pluggable (SFP) transceivers for use with fiber connections and copper connections.
See Optical Interface Support in EX2200 Switches.
PoE ports provide electrical current to devices through the network cables so that separate
power cords for devices such as IP phones, wireless access points, and security cameras
are unnecessary. EX2200 switches are available with full (all 24 or 48 built-in network
ports) or no PoE capability. Full PoE models are primarily used in IP telephony
environments.
EX2200 switches running Junos OS Release 10.3 or later can supply up to 30 W to
individual PoE ports, supporting powered devices that comply with IEEE 802.3af (PoE)
and IEEE 802.3at (PoE+).
NOTE: IEEE 802.3at class 4 powered devices require category 5 or higher
Ethernet cables.
EX2200 switches running Junos OS Release 10.2 or earlier can supply up to 15.4 W to
individual PoE ports, supporting powered devices that comply with IEEE 802.3af (PoE).

Site Preparation Checklist for EX2200 Switches
Juniper Networks EX Series Ethernet Switches provide scalable connectivity for the
enterprise market, including branch offices, campus locations, and data centers. The
switches run under the Juniper Networks Junos operating system (Junos OS), which
provides Layer 2 and Layer 3 switching, routing, and security services. The same Junos
OS code base that runs on EX Series switches also runs on all Juniper Networks J Series,
M Series, MX Series, and T Series routers.
