Switch for PoE access layer

The HPE Juniper Networking EX4100-F-48P is a managed Layer 3 desktop switch with 48 PoE+ ports and a 740W PoE power budget. It includes four 1GbE/10GbE SFP/SFP+ uplink ports and four 10GbE stacking or uplink ports. The unit supports cloud management via Mist AI and Juniper Wired Assurance.

Suited for PoE-heavy access deployments

This switch fits networks that need to power many devices such as access points, cameras or phones from a single rack unit. It is not for buyers who require higher port speeds than 1GbE on the access ports. It is also not for teams that prefer a purely on-premises management model without cloud connectivity.

PoE budget of 740W

The total PoE power budget of 740W determines how many ports can simultaneously deliver the maximum 30W per port. Exceeding this budget will limit the number of fully powered devices. Verify the aggregate draw of your connected endpoints before deployment.

Questions about this item

What rack space and clearance does the 17.36 x 1.72 x 12.26 inch chassis require?

The switch occupies 1U of rack height at 1.72 inches tall, with a depth of 12.26 inches; allow additional rear clearance for cable bends and power-supply airflow.

What is the correct sequence for loading the PoE budget across the 48 ports?

Connect powered devices first, then verify the cumulative draw stays within the 740 W budget using the management interface; the common mistake is exceeding the budget before enabling port-level limits.

Which components are field-replaceable and what is the typical replacement cycle?

The internal fan tray and power supply are hot-swappable; fans typically run five years under continuous operation, while the power supply is rated for a similar service life.
