The Juniper EX4300-48MP is a switch from the Juniper EX4300 family with 48 ports of 1GbE PoE++ RJ45 (24 × 10GbE), 4 ports of 40GbE QSFP+, front-to-back airflow and AC power. It runs Junos OS. This unit is refurbished (used): inspected, powered on and functionally tested by Townsend Networks technicians before listing. One switch per order, with a rack-mount kit and the power cable(s) to match.
- HOW IT DIFFERS
- EX4300-48MP is the multigigabit model: 24 ports at 10/100/1000BASE-T and 24 ports at 100/1000/2500/5000/10000BASE-T, with 95 W PoE and a 1400 W AC power supply that provides up to 1100 W of PoE++ power. Its sister EX4300-24P has 24 ports at 10/100/1000BASE-T with PoE-plus on a 715 W supply that provides 565 W, so the 48MP carries more multigigabit ports and a larger PoE budget.
