HPE Juniper EX4300-48P Layer 3 Switch

The HPE Juniper EX4300-48P is a rackmount Layer 3 switch built for wired networking environments that require routing between VLANs. It provides 48 copper ports operating at 10/100/1000Base-T speeds with PoE-plus capability for powering attached devices. An uplink module slot allows flexible high-speed aggregation toward the network core.

48 PoE-plus ports and 1100 W AC power supply

The chassis delivers 48 primary ports with 24 ports specified for Gigabit Ethernet connectivity and a total PoE-plus power budget of 1100 W from the integrated AC supply. This budget supports power-hungry endpoints such as wireless access points, IP cameras and VoIP phones without external injectors. Rackmount format ensures standard cabinet installation and front-to-rear airflow alignment.

Upgrade from Layer 2 edge switches

Moving from a pure Layer 2 edge switch adds IP routing, static routes and RIP/OSPF support directly in the access layer, reducing hop count to the core. The jump is worth it when you need to segment broadcast domains locally or run DHCP relay without traversing an upstream router. Buyers who only need basic switching and have no routing requirement will not use the Layer 3 feature set.

Questions about this item

What uplink options does the EX4300-48P uplink module support?

The uplink module accepts optional transceivers for 1 GbE or 10 GbE links; the switch ships without transceivers so you choose the speed and distance you need.

What rack hardware is required to mount the EX4300-48P?

The 1 U chassis includes front-mount brackets for a standard four-post rack; two-post mounting requires a separate shelf or tray.

How do you bring the EX4300-48P online after racking it?

Connect the 1,100 W AC power cord, wait for the power LED to turn solid green, then use the console port for initial CLI configuration before linking network cables.
