48-port Gigabit Layer 3 switch

The Juniper EX4200-48PX is a 1U rackmount Layer 3 switch with 48 Gigabit Ethernet ports and a single expansion slot. It supports Virtual Chassis technology to manage multiple units as one logical device. The unit is designed for data centre, campus and branch office deployments.

PoE+ and redundant power support

All 48 RJ-45 ports deliver Power over Ethernet for attached devices such as access points or IP phones. The chassis accepts 110 V AC and 220 V AC input and supports a redundant power supply for high availability. A dedicated stack port enables resilient interconnects between switches.

Upgrade from non-PoE or unmanaged stacks

This switch replaces older 10/100 or non-PoE Gigabit stacks that lack Layer 3 routing and Virtual Chassis simplification. The jump is worth it when you need PoE on every port, single-pane management across a stack, and redundant power in a 1U form factor. It is not for buyers who require 10G uplinks or higher port density than 48.
