EX4300-48T Overview
Forty-eight copper access ports without PoE
EX4300-48T is Juniper’s 48-port 10/100/1000BASE-T Ethernet switch. Unlike EX4300-48P, this T model has no PoE-enabled ports, so it cannot supply PoE power to access points or phones. Confirm the complete label before using a procurement request that simply says EX4300 48-port.
Separate built-in QSFP+ links from the optional uplink module
Four 40-Gigabit Ethernet QSFP+ ports are built into EX4300-48T and are configured as Virtual Chassis ports by default. A separate EX-UM-4X4SFP module adds four SFP/SFP+ uplink ports; it is an option, not a built-in part of the base order. List the intended port role, module and qualified transceivers or cables in the quotation. Juniper lists QSFP+ DAC cables for Virtual Chassis separately.
Check the base AC and AIR OUT package
The original EX4300-48T configuration includes one 350 W AC power supply and two AIR OUT (AFO) fan modules. AFO denotes front-to-back airflow. EX4300-48T-AFI reverses airflow, DC suffixes identify different power options, and the -S spare chassis does not include fans or power supplies by default. Verify actual module labels and any requested second supply rather than assuming all variants contain the same components.
Account for manufacturer lifecycle milestones
Juniper’s official EX Series lifecycle table includes EX4300-48T in the EX4300 P/T group: EOL was announced on 24 June 2022, the last-order date was 31 March 2024, and the published end-of-support date is 31 March 2029. This is a legacy procurement item after the manufacturer last-order date. A future support milestone does not prove that a particular offered serial has an active or transferable support contract. Confirm serial eligibility, software rights, condition, warranty provider and the replacement plan in the quotation.
