Description

The EX4300 48-port PoE+ switch is a Layer 2/3 access switch from the Juniper EX4300 line, built for campus, branch office and data centre access deployments that need high-density Gigabit PoE+ for IP telephony and wireless access points. It suits pay-as-you-grow Virtual Chassis stacks with 10GbE and 40GbE uplinks to aggregation or core.

It provides 48 x 10/100/1000BASE-T PoE+ (802.3at) ports delivering up to 30 W per port, plus 4 fixed 40GbE QSFP+ ports that are Virtual Chassis capable. An optional EX-UM-4X4SFP module adds four 1GbE/10GbE SFP+ ports. Switching capacity is 248 Gbps unidirectional and 496 Gbps bidirectional, with wire-speed throughput of 369 Mpps. This variant uses an 1100 W AC power supply with front-to-back airflow (AFO) in a 1U chassis.

Virtual Chassis supports up to 10 members over a 320 Gbps interconnect, managed as a single logical device. It works with the EX-UM-4X4SFP uplink module and with 1GbE SFP, 10GbE SFP+ and 40GbE QSFP+ optics and DAC cables. Base operation uses the Flex Standard feature set, with optional Flex Advanced and Flex Premium upgrades.

FAQs

Q: Does the EX4300-48P need a licence to operate?
A: No additional licence is needed for base operation. The Flex Standard feature set ships with the Junos OS image. Flex Advanced and Flex Premium are optional upgrades, and MACsec requires a separate licence.

Q: What power supply does this model use?
A: It uses an 1100 W AC front-to-back airflow (AFO) power supply with autosensing 100-120 V / 200-240 V input. The supply is hot-swappable and load-sharing, and a second supply can be added for redundancy. The spare part is JPSU-1100-AC-AFO.

Q: How do I add 10G uplinks?
A: Fit the optional EX-UM-4X4SFP uplink module, which adds four 1GbE/10GbE SFP+ ports. The switch also has four fixed 40GbE QSFP+ ports.

Q: Can it be stacked?
A: Yes. Virtual Chassis combines up to 10 EX4300 or EX4600 switches over a 320 Gbps interconnect and can interoperate with QFX5100 switches. A QSFP+ DAC cable for the Virtual Chassis link is ordered separately.

Q: Which rack and wall mounting kits does it work with?
A: It works with the EX-RMK rack-mount kit, the EX-4PST-RMK 4-post kit and the EX-WMK wall-mount kit.
