48-port PoE+ Layer 3 switch

The EX2300-48P is a managed Layer 3 switch with 48 RJ45 ports supporting 10/100/1000BASE-T and PoE+. It includes four SFP/SFP+ uplink ports for 1GbE or 10GbE connectivity. The unit is rack-mountable and designed for converged enterprise network access deployments.

Installation and common issues

The switch ships as a fixed-configuration desktop or rack-mount unit with standard mounting hardware. Optics for the four SFP/SFP+ uplinks are sold separately and must be sourced to match the desired link distance and fibre type. Virtual Chassis technology allows up to four switches to be interconnected and managed as a single logical device, simplifying initial onboarding through Juniper Mist Wired Assurance.

Capacity and headroom

The MAC address table holds 16K entries and supports jumbo frames up to 9216 bytes. Layer 3 resources include 1,500 ARP entries, 512 IPv4 unicast route prefixes and 2,048 multicast groups. The switch supports 4093 VLANs with 2044 active simultaneously. Each port provides eight hardware egress queues with strict priority and shaped deficit weighted round-robin scheduling for traffic shaping.

Questions about this item

How do I verify the EX2300-48P is forwarding at wire-rate after setup?

Check the Packet Forwarding Engine counters in the CLI or Mist dashboard; they should show line-rate throughput on all 48 RJ45 and 4 SFP+ ports with zero drops when control-plane features are enabled.

What ships with the EX2300-48P and what must I purchase separately?

The switch includes the chassis and 48 PoE+ RJ45 ports; the 4 SFP/SFP+ uplink transceivers are sold separately and must be bought to activate the 1/10GbE uplinks.

Which uplink option should I choose for the 4 SFP+ slots on the EX2300-48P?

Select 1GbE SFP modules for standard aggregation links or 10GbE SFP+ modules when higher uplink bandwidth to the core is required; both form factors fit the same four slots.
