Juniper EX4100-48P PoE Access Switch

The Juniper EX4100-48P is a fixed-configuration Gigabit Ethernet access switch designed for enterprise wiring closets and campus edge deployments. It provides 48 PoE+-capable 10/100/1000BASE-T downlink ports alongside four 10GbE SFP+ uplink ports, delivering high-density Power over Ethernet to endpoints such as IP phones, wireless access points, and IoT devices. The switch is built around Juniper's Junos operating system, ensuring a consistent, feature-rich network operating environment across the enterprise stack.

A defining characteristic of the EX4100-48P is its native integration with Juniper's Mist AI cloud management platform. When managed through Mist, the switch benefits from AI-driven analytics, automated event correlation, and streamlined zero-touch provisioning, substantially reducing manual configuration effort in large-scale deployments. Mist-driven telemetry provides granular visibility into port-level performance, PoE budget consumption, and client connectivity events, enabling faster troubleshooting without requiring on-site intervention.

The EX4100-48P supports advanced Layer 2 and Layer 3 features including OSPF, RIP, static routing, VLAN segmentation, RSTP/MSTP, LACP-based link aggregation, and 802.1X port-based network access control. The switch also supports Virtual Chassis technology, allowing multiple EX4100 units to be interconnected and managed as a single logical device, simplifying operations and scaling capacity within a wiring closet without increasing management complexity.

Ideal for

• Deploying high-density PoE+ to power and connect Wi-Fi 6/6E access points across enterprise campus buildings managed centrally via Mist AI
• Providing wiring-closet access switching for IP telephony rollouts requiring 802.3at PoE+ on every port without dedicated injectors
• Consolidating multiple standalone access switches into a single logical Virtual Chassis unit to reduce management overhead in large office floors
• Enforcing 802.1X network access control and dynamic VLAN assignment for BYOD and guest segmentation in regulated enterprise environments
• Supporting IoT endpoint connectivity including badge readers, cameras, and building-automation devices under unified Mist-managed policy
• Enabling zero-touch provisioning workflows for rapid branch or satellite-office switch deployment with minimal on-site IT presence
