Juniper T Series T4000 — End-of-Life & EOSL Dates

PAST VENDOR SUPPORTJuniper ended support in August 2024.

Juniper T Series T4000 — router. Published end-of-sale (last order) and end-of-support (EOSL) dates from Juniper JTAC End-of-Life bulletins.

Every tracked Juniper T Series T4000 SKU group is past Juniper end of service life (last group Aug 2024). Units in production should be treated as unsupported. For past-EOSL units, weigh third-party maintenance, spares, replacement, or a documented run-to-failure.

  • Vendor-published date, source-linked
  • Category: router

Support-lifecycle timing and source confidence only. Higher means more runway. It is not a risk, safety or compliance rating. How it is calculated

Figure 1. Juniper issues no software maintenance and no security fixes for this product. Third-party maintenance, spares or replacement are the paths from here. EOSL.ai sells none of them and takes no placement fee.

The vertical rule is today; bars entirely to its left are past support.

Options from here

The Juniper T Series T4000 is past Juniper end of service life. These are the paths teams take from here:

Third-party maintenance

Keep it in production past the OEM cutoff with an independent maintainer.

Pre-stock spares

Buy spares now, while units still circulate on the secondary market.

Plan replacement

It is unsupported today. Set a migration timeline and budget.

Run to failure

Low-criticality role: document the risk, harden backups, retire on your terms.

Independent and informational. EOSL.ai sells no hardware and no maintenance, and lists no paid placements. Third-party maintenance keeps unsupported gear in production past the OEM cutoff; whether it fits depends on the role the asset plays.
