Description

The EX3400 is a fixed-configuration 1U Layer 2/3 access switch from the Juniper EX Series, built for campus wiring closets and enterprise access deployments. It suits sites that need 48 Gigabit access ports with 10G and 40G uplinks, and it can also be used in small stacked deployments or as an access switch in Juniper campus fabric roles.

The EX3400-48T provides 48 x 10/100/1000BASE-T ports, 4 x 1/10GbE SFP/SFP+ uplink ports and 2 x 40GbE QSFP+ ports, for 54 GbE ports per system. This is the non-PoE model, with a PoE budget of 0 W. It uses AC power with a 150W power supply rating and redundant fans with front-to-back airflow, so it suits racks where the port side faces the cold aisle. The 40GbE ports are preconfigured as Virtual Chassis ports and can alternatively be used as uplinks, allowing up to 10 switches to be managed as one device.

It runs Junos OS, with Layer 2 features, RIP and static routing in the base software. It works with standard 1/10GbE SFP/SFP+ and 40GbE QSFP+ optics.
