Switch overview

The Juniper EX4300-48P is a rackmount Ethernet switch built for networks that need high-density copper connectivity with inline power. It suits campus access layers, branch offices and wiring closets where devices such as IP phones, wireless access points and cameras draw power over the cable.

Port capacity

Forty-eight RJ-45 ports deliver 10/100/1000Base-T speeds and every port supports PoE+ for powered devices. Four 40 Gigabit Ethernet expansion slots provide uplink flexibility for aggregation or core links.

Sustained operation

A 1100 W AC power supply feeds the full PoE+ budget across all forty-eight ports without oversubscription. The fixed chassis dissipates heat through front-to-rear airflow designed for continuous duty in standard racks.

Questions about this item

What does 48 PoE+ ports mean for devices I can power directly?

All 48 Gigabit Ethernet RJ-45 ports deliver PoE+ power, so IP phones, wireless access points and cameras can run without separate adapters up to the 1100 W AC budget.

How do the 40 Gigabit Ethernet expansion slots connect to the core?

The four expansion slots accept SFP transceivers for uplink speeds up to 40 Gbps, letting you aggregate traffic to a backbone switch or router.

What rack space and weight should I plan for?

The chassis is a rackmount unit weighing 22 kg; it fits a standard equipment rack and requires the 1100 W AC power supply at the rear.
