Keep access networks stable as endpoint counts rise. The Juniper EX4400-48XP pairs 48 PoE-enabled 1 GbE ports with 2 x 100 GbE uplinks, giving infrastructure teams the port density and backhaul capacity needed for modern campus, branch, and aggregation designs. High PoE capacity matters when the switch is expected to power phones, wireless access points, cameras, and other edge devices without adding mid-span injectors or extra power circuits. This model is built for those environments where uptime, cable simplicity, and clean rack design directly affect operating cost. The 100 GbE uplinks help prevent access-layer congestion from becoming a bottleneck, especially in networks carrying voice, video, and dense east-west traffic. For teams standardizing on Juniper switching, the EX4400 family offers a strong fit where performance headroom and port economics both matter. Choose this model when a lower-capacity access switch would force compromises in power delivery, uplink design, or long-term scaling. It is a practical fit for enterprise deployments that need more than basic PoE switching.
