The Juniper Networks EX2200-C Ethernet Switch with Virtual Chassis technology delivers a compact, silent, and power efficient platform for low-density micro branch deployments and commercial access or enterprise workgroup environments outside the wiring closet. Featuring 12 10/100/1000BASE-T access ports with and without Power over Ethernet Plus (PoE+) in a fanless design, the EX2200-C switches deliver a powerful solution for supporting services such as unified communications, IP telephony, closed circuit television (CCTV), and other applications in office, classroom, hospitality, and other space and wiring constrained environments. Two front panel, dual-purpose (10/100/1000BASE-T or 100/1000BASE-X) uplinks provide operational flexibility. Architecture and Key Components The fixed configuration EX2200 line of Ethernet switches delivers complete Layer 2 and basic Layer 3 switching capabilities to satisfy the low-density branch and low-density wiring closet connectivity requirements of today’s high-performance businesses. The EX2200-C models extend that reach into workgroup environments that reside outside the wiring closet, including micro branch offices, retail access applications, education, hospitality, and other locations where the switch is deployed in open areas. Two models are available. The EX2200-C-12T-2G offers 12 front panel 10/100/1000BASE-T ports for connecting to networked devices. The EX2200-C-12P-2G includes support for the IEEE 802.3at PoE+ standard for powering networked devices such as telephones, video cameras, multiple radio IEEE 802.11n wireless LAN (WLAN) access points, and video phones in converged network environments. The EX2200-C switches also include two front panel, small form-factor pluggable transceiver (SFP) GbE uplink ports, and two RJ-45 copper GbE uplink ports. Up to two of the uplink ports can be used simultaneously, providing the flexibility to connect to higher layer devices such as aggregation switches or routers over unshielded twisted pair (UTP) or fiber optic cabling. The uplink ports can also be configured as Virtual Chassis interfaces and connected via standard GbE optics interfaces; the last two are preconfigured by default as Virtual Chassis ports. A fixed internal power supply ensures operational simplicity.
