Network switch Extreme Networks EX4100-F-48P, 48x RJ-45 PoE, 2x SFP, 2x SFP+, 256 Gbit/s, 1U, grey

The Extreme Networks EX4100-F-48P is a 1U rack-mount Ethernet access switch with 48 RJ-45 ports that support Power over Ethernet (PoE), two SFP and two SFP+ slots, and a 256 Gbit/s switching capacity. Designed for access-layer deployments in campus, branch and small to medium data center networks, the switch supports a broad set of IEEE networking standards including VLAN tagging, quality of service, port-based authentication and PoE/PoE+/PoE++ power delivery. The EX4100-F-48P is available in a grey chassis and provides a 64K MAC address table suitable for VoIP phones, IP cameras, wireless access points and general Ethernet edge connectivity.

Advantages

The EX4100-F-48P combines high port density with multi-gig and 10G uplink flexibility, an industry-standard feature set and support for cloud-based management. It supports advanced access features such as EVPN-VXLAN overlay, group-based policy microsegmentation, MACsec encryption and flow-based telemetry while offering a compact 1U form factor and a 256 Gbit/s switching fabric. PoE capabilities include support for standards up to IEEE 802.3bt with a high overall power budget and perpetual/fast PoE options to maintain power for endpoints during reboots or initial power-up.

Suitable for

• Enterprise campus access switches for office floors
• Branch office networks requiring PoE for phones and wireless APs
• Small to medium data center top-of-rack or access-layer deployments
• IP video surveillance and security camera networks
• Networks requiring cloud management and telemetry for AIOps

How to use

Install the EX4100-F-48P into a standard 19-inch rack occupying 1U of space and connect power according to site electrical requirements. Attach access devices to the RJ-45 ports and fiber or high-speed uplinks to the SFP/SFP+ slots as required. For cloud management, onboard the switch into the Juniper Mist Wired Assurance portal to perform Day 0 provisioning, Day 1 configuration and Day 2+ management. Configure VLANs, QoS, PoE budgets and any access control or EVPN-VXLAN overlays through the Junos OS CLI or via the Mist cloud management interface. Monitor flow telemetry and event data to identify anomalies and tune policies as needed.

Usage recommendations

For deployments that rely on powered devices, plan the PoE power budget per rack and verify perp-port PoE requirements (up to 90 W per port supported) before connecting endpoints. Use the SFP/SFP+ uplinks for aggregation to distribution or core switches to ensure adequate uplink bandwidth. Enable cloud telemetry and flow-based monitoring for improved visibility and faster troubleshooting. When high availability is required, consider Virtual Chassis configurations and redundant power for chassis-class availability.
