48-port Layer 3 switch with uplinks

The EX3400-48P is a Layer 3 Ethernet switch providing 48 Gigabit Ethernet ports for wired network access. It includes uplink interfaces using SFP modules and supports stacking for larger deployments. The unit is designed for rack or wall mounting in enterprise environments.

Suited for converged enterprise access

This switch fits networks carrying data, voice and video where Layer 3 routing at the access layer is required. Virtual Chassis support allows up to 10 units to be managed as one logical device. Buyers needing Power over Ethernet on the 48 downlink ports or higher-density 10 Gigabit downlink ports should consider other models.

Uplink and stacking speeds decide fit

The uplink and stacking ports operate at 10 Gigabit and 40 Gigabit speeds using SFP and 40 Gigabit interfaces. These speeds determine the upstream bandwidth available to the 48 Gigabit downlinks. Verify that the uplink capacity matches the aggregation requirements of the wiring closet.

Questions about this item

Does the EX3400-48P ship with SFP modules for the uplink ports, or must they be purchased separately?

The switch includes 48 built-in Gigabit Ethernet ports and uplink interfaces that accept SFP modules; SFP transceivers are not included and must be sourced separately for fibre or copper uplinks.

Which uplink speed should I choose — 10 Gigabit or 40 Gigabit — for a growing campus network?

The unit provides four 10 Gigabit Ethernet stack ports and two 40 Gigabit Ethernet stack ports; use 10 GbE for typical access-layer uplinks and 40 GbE when you need higher aggregation bandwidth between closets.

What does the 48-port Gigabit count mean for actual device density in a wiring closet?

You can connect up to 48 endpoints — such as VoIP phones, wireless access points, or workstations — at 1000Base-T speeds directly on the switch without adding extra patch panels.
