Juniper EX3400 vs EX4300: Campus Switch Procurement Guide

Where Juniper EX3400 and EX4300 switches fits

EX3400 and EX4300 models appear in campus access deployments and replacement inventories. Exact suffixes and hardware generations affect port configuration, PoE, uplinks and Virtual Chassis planning.

Technical and commercial checks

  • Record port count, PoE class and endpoint power demand.
  • Confirm uplink type, optics and Virtual Chassis cabling.
  • Check Junos release and supported mixed-member combinations.
  • Validate AC or DC power, airflow and mounting components.

How to make the selection

For an existing Virtual Chassis, compatibility and operational consistency can outweigh the price of a newer standalone model. For a new deployment, compare lifecycle, capacity and management requirements rather than reproducing a legacy design automatically.

Common procurement risks

  • Mixing unsupported Virtual Chassis members.
  • Ordering a non-PoE model for powered endpoints.
  • Ignoring airflow and power-supply suffixes.

Acceptance checklist

Browse YYST Global enterprise IT hardware and use the exact model number when requesting stock, price, lead time or replacement guidance.
