Juniper EX3300 end of life: support dates
By Nico De Muynck · Updated August 2, 2026
This switch is past its End of Support date.
The Juniper EX3300 reached its End of Support on June 30, 2024. That is the hard stop: after it Juniper provides no support, no hardware replacement and no software fixes.
The EX3300 was the compact Virtual Chassis access switch that sat below the EX4200. It is now past End of Support and no longer receives fixes.
EX3300 lifecycle milestones
These dates come from Juniper's published End of Life milestone table for the EX3300.
| Milestone | Date |
|---|---|
| EOL announced | 2019-02-01 |
| Last order date | 2019-06-30 |
| Last date to convert warranty | 2020-06-30 |
| Same day support discontinued | 2024-06-30 |
| Next day support discontinued | 2024-06-30 |
| End of Support | 2024-06-30 |
EX3300 shared one end-of-life notice with the EX2200 and EX4200, so all three reached End of Support on the same day.
What these dates mean
Last order date is the last day the EX3300 could be ordered from Juniper. Last date to convert warranty is the cutoff for moving a warranty onto a support contract. End of Support is the one that matters most: after it there is no JTAC support, no RMA replacement and no software fixes, so the switch becomes a standing security and compliance risk. For how Juniper's lifecycle works in full, see the Juniper EOL guide.
What replaces the EX3300?
Juniper positions the EX4100 Series as the successor to the EX3300. If you are still running EX3300 hardware in production, budget the refresh rather than waiting for a failed RMA to force it. New to the terminology? See EOL vs EOS vs EOSL.
