Frequently Asked Questions

What is the maximum Virtual Chassis size for EX2300-48T?

The EX2300 supports Virtual Chassis stacks of up to 4 switches. Using the SFP+ uplink ports as Virtual Chassis links, up to 4 EX2300-48T switches can be stacked as a single logical device with one management plane and IP address, providing up to 192 GbE access ports per stack.

Can the EX2300-48T be wall or desktop mounted?

Yes — the EX2300-48T supports rack, wall, and desktop mounting configurations. Optional wall-mount brackets are available for installations where rack mounting is not practical, such as conference rooms, small offices, or utility closets.

Does the EX2300-48T support BGP routing?

BGP is not supported on the EX2300 platform — it supports OSPFv2/v3, RIP, and static routing for L3 access deployments. For deployments requiring BGP, the EX4100 or EX4400 series provides full BGP support in the EX access switch family.

The Juniper EX2300-48T delivers 48-port GbE access connectivity with 10G uplinks, Junos OS Layer 3 routing, and Juniper Mist AI management in a compact, versatile form factor — providing cost-effective, cloud-managed GbE access switching for campus branch offices, wiring closets, and small enterprise environments.
