Is the Juniper EX4300 end of life?
Juniper's EX Series hardware milestones page shows three notices for the models on this page. The 24- and 48-port T and P models, including the AFI, DC and TAA versions: end of life announced 24 June 2022, last order 31 March 2024, end of support 31 March 2029. The EX4300-32F and EX4300-32F-DC (TSB105633): last order 31 March 2026, end of support 31 March 2029. The EX4300-48MP (TSB109284, announced 29 June 2026): last order 29 December 2026, end of support 29 December 2031.
What do AFI and AFO mean on an EX4300?
Airflow direction. Juniper labels fans and power supplies AIR IN (AFI) for back-to-front airflow and AIR OUT (AFO) for front-to-back airflow. The EX4300-48T-AFI ships with AFI fan modules and power supply; the standard EX4300-48T ships AFO. Match the airflow to the hot and cold aisles of the rack it goes into.
Can EX4300 switches be stacked, and with what?
Up to 10 EX4300 switches form a Virtual Chassis. The built-in QSFP+ ports are set up as Virtual Chassis ports by default and can be reconfigured as network ports. An EX4300 can also be a line card member of a mixed Virtual Chassis with EX4600 switches, where the EX4600 takes the primary and backup roles.
Which uplink modules fit the EX4300?
The 24- and 48-port T and P models take the 4-port 10GbE SFP+ module EX-UM-4X4SFP. The EX4300-32F takes the 2-port 40GbE QSFP+ module EX-UM-2QSFP or the 8-port 10GbE SFP+ module EX-UM-8X8SFP. The EX4300-48MP takes the EX-UM-2QSFP-MR (two 40GbE or 100GbE ports) or the EX-UM-4SFPP-MR (four 1GbE or 10GbE ports). A switch listing does not include an uplink module unless it says so.
What condition and warranty come with a Juniper EX4300 switch from Townsend?
Each listing prints its own condition. Units sold as new, refurbished or used are bench tested before they are listed: every port and module slot is checked and the previous owner's configuration is erased. They are covered by the Townsend warranty from the date of delivery; if the hardware fails in normal use we repair it or replace it with a tested unit, and the length and terms are on our warranty page. Unused hardware can be returned within 30 days of delivery. Juniper software licences and support contracts are not part of our warranty.
