Featuring complete Layer 2 and Layer 3 switching capabilities, the EX 3200 series switches satisfy the wiring closet connectivity requirements of today's high-performance businesses. Four platform configurations are available offering 24 and 48 10/100/1000BASE-T ports with either full or partial Power over Ethernet (PoE). The base 24- and 48-port EX 3200 series switches deliver a full 15.4 watts of Class 3 PoE on the first eight ports for supporting IP-enabled devices such as telephones, video cameras and wireless LAN (WLAN) access points in converged networks. The EX 3200 series switches with full PoE deliver 15.4 watts on all 24 or 48 ports to support high-density IP telephony and other converged network environments. The EX 3200 series Ethernet switches also support optional four-port Gigabit Ethernet (GbE) and two-port 10 GbE uplink modules with pluggable optics to provide high-speed connectivity to aggregation-layer switches or other upstream devices. A field-replaceable power supply and fan tray minimize mean time to repair (MTTR) for the EX 3200 series switches, ensuring maximum availability. When deployed with an optional external redundant power supply unit, the EX 3200 series switch's power supply becomes hot-swappable.
