This hot-swappable card delivers four 10/100/1000BASE-TX ports that can be inserted without powering down the switch, reducing MTTR by over 90% and ensuring continuous transaction processing while maintaining strict compliance with SLAs.
A retail chain deploys QFX3100 switches at regional stores and uses the QFX3100-NM-4GE module to aggregate four Gigabit copper links into a single logical WAN uplink. This setup streamlines network configuration, optimizes bandwidth utilization with link-bonding, and delivers up to 4 Gbps of resilient throughput—reducing operational complexity and enhancing application performance across locations.
A healthcare provider implements isolated out-of-band (OOB) management on its QFX3100 core switches using the QFX3100-NM-4GE module. Four dedicated 10/100/1000BASE-TX ports connect to an independent management network, enabling secure remote access, automated firmware updates, and rapid troubleshooting without impacting production traffic. This approach strengthens security posture and improves service availability.
