Description

Juniper EX4300-24T — 24-Port GbE Access Switch with 4x QSFP+ 40GbE

Technical Identity

The Juniper Networks EX4300-24T is a fixed-configuration 1U Ethernet access switch with 24x 10/100/1000BASE-T (RJ-45) ports and 4x QSFP+ 40GbE ports. Per the Juniper EX4300 datasheet, the platform delivers 448 Gbps switching capacity and 333 Mpps forwarding, runs Junos OS, and its QSFP+ ports operate by default as Virtual Chassis ports (VCPs) forming a 320 Gbps interconnect. Condition: Refurbished.

Specifications

  • Brand: Juniper Networks
  • Model / MPN: EX4300-24T
  • Product type: Layer 2/3 Ethernet access switch
  • Product family: Juniper EX4300 line
  • Access ports: 24x 10/100/1000BASE-T RJ-45
  • Uplink / VCP ports: 4x QSFP+ 40GbE (Virtual Chassis ports by default)
  • Switching capacity: 448 Gbps (per Juniper EX4300 datasheet)
  • Forwarding rate: 333 Mpps
  • MAC table: 64,000 entries
  • Form factor: 1U rack-mount
  • Operating system: Junos OS
  • Virtual Chassis: up to 10 members
  • Condition: Refurbished

Engineering Context

The EX4300 line is designed for standalone access or stacked operation: up to 10 switches interconnect over the QSFP+ VCPs into a single managed Virtual Chassis with a 320 Gbps backplane, and the platform also participates in Virtual Chassis Fabric and Junos Fusion architectures. The -24T suffix denotes the 24-port, non-PoE copper model of the line. Juniper lists a 350 W AC power supply for the copper EX4300 models.

Use Cases

  • Campus and branch access layer for 1GbE desktops, phones, and access points
  • Server access at 1GbE with 40GbE aggregation over the QSFP+ ports
  • Virtual Chassis stacks that reduce managed devices and configuration points
  • Small-site collapsed distribution where L3 routing at the access edge is required

What This Is NOT

  • NOT a PoE switch. Inline power requires the EX4300-24P / EX4300-48P variants; the -24T provides no PoE.
  • NOT a 10GbE access switch. The 24 access ports are 1GbE RJ-45. SFP+ 10GbE requires an optional EX4300 uplink module (not included) or a different platform.
  • NOT the multigigabit EX4300-48MP. This is the standard 1GbE copper model.
  • NOT a QSFP28 / 100GbE platform. The four QSFP+ ports are 40G and default to Virtual Chassis (VCP) mode.
  • NOT supplied with transceivers, DAC cables, uplink modules, or rack accessories unless explicitly stated in the listing.
  • NO Juniper software licenses or support contracts are included or transferred; advanced Junos features may require Juniper feature licenses per Juniper policy.

Compatibility & Hard Constraints

  • Typical deployment: standalone access switch or Virtual Chassis with other EX4300 members (mixed-VC rules per Juniper documentation).
  • Optics and cables: Juniper-qualified QSFP+ transceivers and DACs for the 40G ports; verify against the EX4300 hardware compatibility list.
  • Port mode: QSFP+ ports ship in VCP mode; use as 40GbE network uplinks requires explicit Junos configuration.
  • Lifecycle: Juniper has announced end of life for the EX4300 line (published EOL trackers list EOL 2022 and end of support 2029) — verify current support status before deployment.
  • Pre-deployment verification: confirm Junos release, feature licensing, and power option against the unit label.

Frequently Asked Questions (FAQ)

Q. What is the Juniper EX4300-24T?
The EX4300-24T is a 1U Juniper EX4300-line access switch with 24x 10/100/1000BASE-T RJ-45 ports and 4x QSFP+ 40GbE ports, rated at 448 Gbps switching capacity and 333 Mpps, running Junos OS.

Q. Can the 4x QSFP+ ports on the EX4300-24T be used as 40GbE uplinks?
By default the QSFP+ ports operate as Virtual Chassis ports (VCPs). They can be converted to network (uplink) ports through Junos configuration; verify the procedure for your Junos release.

Q. Does the EX4300-24T provide PoE?
No. The -24T model provides no inline power. PoE/PoE+ is available on the EX4300-24P and EX4300-48P variants.

Q. Are Junos licenses included with this EX4300-24T?
No license or support entitlement is included or claimed. The switch runs Junos OS; advanced features may require Juniper feature licenses purchased separately per Juniper policy.

Q. Is the EX4300-24T end of life?
Juniper has announced end of life for the EX4300 line; published trackers list EOL in 2022 with end of support in 2029. The platform remains widely deployed; verify support status for your environment.
