This manual provides essential information for the installation, operation, and maintenance of the Juniper EX2300-C-12T Ethernet Switch. The EX2300-C-12T is a compact, high-density, and cost-effective solution designed for small network environments where space and power efficiency are critical. It is ideal for access-layer deployments in micro branches, retail, and workgroup environments, as well as for converged network access in larger networks.
The EX2300-C-12T features 12 10/100/1000BASE-T ports and supports IEEE 802.3af Power over Ethernet (PoE) or 802.3at PoE+ for powering attached network devices. It also includes optional front panel 10GbE uplink ports for connections to higher-layer devices. This model supports Juniper's Virtual Chassis technology, allowing up to four switches to be interconnected and managed as a single logical device. It can also function as a satellite device in a Juniper Junos Fusion Enterprise deployment.
