Juniper Networks EX4300-48T

The Juniper EX4300-48T is a 1U L3 access switch offering 48 x 1000Base-T RJ-45 ports and 4 x 40G QSFP+ uplinks, with a switching capacity of 496 Gbps and a forwarding rate of 369 Mpps. Its 64,000-entry MAC table, 32,000 IPv4 routes, 18,000 IPv6 routes, and support for up to 20,000 neighbors provide robust routing capabilities for an access-layer device. Running JUNOS, it supports BGP, OSPF, IS-IS, MPLS, and BFD with 2 GB of RAM and 2 GB of flash storage.

Compared to the 24T model, the Juniper EX4300-48T doubles the copper port density to 48 Gigabit ports within the same 1U chassis, making it the natural choice for high-density user access tiers. It suits enterprise, campus, and open-plan office deployments requiring broad connectivity with 40G uplinks to the aggregation layer. Genuine hardware, manufacturer warranty.
