48-port PoE++ switch for managed networks

The HPE Juniper Networking EX4000-48MP is a managed Layer 3 switch that provides 48 RJ45 ports with PoE++ and four SFP+ uplinks. Eight RJ45 ports support multi-gigabit speeds up to 2.5G while forty ports operate at 10/100/1000BaseT. It delivers a 960W PoE budget with up to 60W per port for high-power devices. Cloud-native AI features integrate with Juniper Mist Wired Assurance.

Verify rack space and uplink optics before ordering

The unit measures 17.36 x 1.71 x 11.97 inches and weighs 5.2 kg, requiring a standard 1U rack slot. SFP+ transceivers for the four uplink ports are sold separately and must be sourced for the desired fibre or copper link. Ensure the site power infrastructure can sustain the 960W PoE budget plus the 92W base consumption. Confirm that connected endpoints negotiate IEEE 802.3bz or 802.3bt correctly.

Fixed chassis with front-to-rear airflow

The fixed form factor uses front-to-rear cooling suited to standard data-centre aisles. All 48 copper ports and four SFP+ cages sit on the front panel for straightforward patching. Perpetual PoE and Fast PoE keep powered devices alive during firmware reloads or brief power events. Hardware queues per port total 12 with strict priority and weighted deficit round-robin scheduling for consistent QoS.

Questions about this item

What comes in the box with the EX4000-48MP and do I need to buy SFP+ optics separately?

The switch includes the 48-port Multi-Gig chassis with 48 RJ45 ports and 4 SFP+ uplinks. Optics for the SFP+ ports are sold separately, so order the transceivers you need for fibre or direct-attach links.

How should I choose between the 8 multi-gig ports and the 40 standard gigabit ports for my devices?

The 8 ports support 100M, 1G and 2.5GBaseT speeds, while the remaining 40 ports run at 10/100/1000BaseT. Connect 2.5G-capable endpoints to the first 8 ports and standard gigabit devices to the other 40.

What does the 960W PoE++ budget mean for real-world deployments?

The 960W budget delivers up to 60W per port across all 48 PoE++ ports. You can power high-draw devices such as pan-tilt-zoom cameras or multi-radio access points on every port simultaneously without exceeding the switch's power supply.
