Form factor


  • The EX2300-C Ethernet Switch offers a compact, power-efficient, cost-effective solution for low-density branch offices and enterprise workgroups. Featuring a fanless design, the EX2300-C is completely silent, making it ideal for open office deployments and commercial applications such as in retail stores.
  • The EX2300-C offers 12 front-panel 10/100/1000BASE-T access ports and two optional SFP+ 10GbE uplink ports for connecting to higher level devices. Access ports are available both with and without IEEE 802.3af Power over Ethernet (PoE) or 802.3at PoE+ for powering attached network devices.
  • Working with a compatible EX Series switch, the EX2300-C supports Juniper’s unique Virtual Chassis technology. Up to three of the switches can be interconnected with a fourth Virtual Chassis-compatible EX Series switch, enabling them to be managed as a single device. The EX2300-C can also act as a satellite device in a Junos Fusion Enterprise deployment, which combines large numbers of access switches into a logical management platform.
