Purpose-built access switch

The Juniper EX4300-24T is a 1U rackmount Layer 3 switch with 24 Gigabit Ethernet ports running at 10/100/1000Base-T. It serves wiring closets and small data-centre pods that need wire-speed switching plus static or dynamic routing without a separate router appliance. Uplink capacity is provided by a hot-swappable uplink module chosen at purchase.

Pre-deployment checklist

Verify that your rack has a free 1U slot and that the site power budget covers the switch and its selected uplink module. Confirm the uplink module SKU matches the fibre or copper media you plan to run to the core. Ensure your management network can reach the out-of-band port for initial configuration and that your licensing entitlement covers the Layer 3 feature set you intend to enable.

Sustained-load behaviour

The forwarding ASIC maintains line-rate performance across all 24 ports during prolonged traffic bursts, while the modular uplink absorbs aggregate throughput without head-of-line blocking. Thermal design keeps component temperatures stable in a fully populated rack row, and redundant fan trays continue airflow if a single rotor fails. Junos OS continues to process routing updates and telemetry streams without control-plane saturation during extended convergence events.

Questions about this item

Does the EX4300-24T ship with any uplink modules or must they be purchased separately?

The switch includes 24 fixed 10/100/1000BASE-T ports; uplink modules are not included and must be bought separately to add fibre or higher-speed uplinks.

How do I decide which uplink module to add to the EX4300-24T?

Choose a module that matches your uplink speed and media — 1 GbE or 10 GbE, copper or fibre — because the chassis accepts a single hot-swappable uplink module.

What does the 24-port 10/100/1000BASE-T rating mean for daily throughput?

Each of the 24 ports auto-negotiates at 10, 100 or 1000 Mb/s, so the switch can forward up to 24 Gb/s of non-blocking Layer 3 traffic when all ports run at gigabit speed.
