EX2200 Switches Hardware Overview
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.
EX2200 Switches
Juniper Networks EX2200 Ethernet switches provide connectivity for low-density environments.
EX2200 switches are available in models with either 24 or 48 built-in network ports and four uplink ports, with Power over Ethernet (PoE) either available in all built-in network ports or not available in any built-in network port. All models provide network ports that have 10/100/1000Base-T Gigabit Ethernet connectors and four uplink ports. These switches run under Junos OS for EX Series switches.
Uplink Ports
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.
Power over Ethernet (PoE) Ports
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).
