EX4300-24P-TAA Use Case
TAA-Compliant VoIP and Wireless for Federal Agencies
In a U.S. federal office bound by TAA regulations, the EX4300-24P-TAA switch powers 24 VoIP handsets and 12 wireless access points over a single 10/100/1000BaseT PoE+ infrastructure with a 715W AC power supply delivering 400W PoE+ output. This configuration ensures FIPS-grade network security, preserves TAA compliance, reduces rack-space footprint, and streamlines voice and data delivery for mission-critical operations.
Industrial Campus IP Surveillance and Access Control
A manufacturing campus deploys 20 high-resolution PoE+ cameras and 4 door-controller panels using the EX4300-24P-TAA’s 400W PoE+ budget to consolidate power and network connectivity. The result is unified management via Junos OS, simplified cable runs, uninterrupted video recording, and improved safety compliance—delivering real-time monitoring with minimal downtime and predictable OPEX.
High-Density Hospitality Wi-Fi and Digital Signage
A convention center equips 18 ceiling-mounted 802.11ac Wave 2 access points and 6 digital signage displays through the EX4300-24P-TAA’s 24-port PoE+ switch, leveraging 400W of PoE+ power. This deployment achieves seamless high-density wireless coverage, centralized QoS enforcement, and dynamic content updates, enhancing guest experience, reducing cabling complexity, and accelerating time-to-market for event setups.
