Description
The Juniper EX4300-48MP-TAA Ethernet Switch delivers carrier-class reliability and high-performance scalability for modern enterprise networks. Designed with Juniper’s Virtual Chassis technology, this switch allows up to ten EX4300 or EX4600 units to operate as a single logical device, simplifying management while providing a pay-as-you-grow architecture for expanding campus, branch, and data center environments.
Featuring 48 multigigabit ports supporting IEEE 802.3bz speeds (100 Mbps to 10 Gbps) and PoE++ up to 95 W per port, the EX4300-48MP-TAA is ideal for high-density deployments of advanced wireless access points, IP telephony, and surveillance devices. Its Layer 2 and Layer 3 switching capabilities ensure optimal performance, security, and control, while MACsec AES-256 encryption provides robust protection against unauthorized access.
Engineered with redundant, hot-swappable power supplies and fans, the EX4300-48MP-TAA offers maximum uptime and operational flexibility. Fully compliant with TAA and RoHS standards, it supports long-term government and enterprise use with a lifetime limited warranty and factory-fresh quality assurance from Juniper Networks.
