Juniper Networks EX 4200, 48-port 10/100/1000BaseT PoE + 930W AC PS, includes 50cm VC cable With the EX4200-48P switch, a business can take part in all manner of access and aggregation deployments

Juniper Networks EX 4200, 48-port 10/100/1000BaseT PoE + 930W AC PS, includes 50cm VC cable With the EX4200-48P switch, a business can take part in all manner of access and aggregation deployments. This is true even of those businesses where space is a premium as this is a compact model that never sacrifices its quality of performance in any way. The switches in the Juniper EX4200 Series are immediately distinguished by their 24 and 48 port fixed-configuration with 10/100/1000BASE-T platforms. Furthermore, they are designed with full and partial ports that present Power over Ethernet (PoE) options. For those that require a long distance link, a fiber platform comprised of a 24 port 100BASE-FX/1000BASE-X SFP system can be used. There are optional items that can be weaved into the system, and they include a 2 port 10GbE uplink module with pluggable optics and a four port Gigabit Ethernet (GbE). The Virtual Chassis technology is a hallmark of Juniper's innovation. This technology makes it possible to connect a full 10 switches through a 128 Gbps backplan to craft a single device. This device can then be used to support upwards of 480 users along with 20 10GbE uplink ports. The Junos operating system is what is utilized to run the system. This new EX4200-48P is a single switch, fixed-platform device. The throughput yields EX4200-24P/24T/24F at 65 Mpps wire speed and at 101 Mpps wire speed. The Data Rate is EX4200-24P/24T/24F at 88 Gbps and at 136 Gbps. The available Port Densities are 10/100/1000BASE-T, 100BASE-FX / 1000BASE-X (SFP), and 10GBASE-X Port Densities. Both a 802.3af compliant Ethernet switch and a PoE injector deliver the power supply options. It is a one rack unit with dimensions of W17.4 x 1.7 x D 16.4 in. All in all, this is one of the more solid Juniper EX Switches.
