Why this score
  • End of service life within ~3 years
  • 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. Support runs to Jun 2029. Budget a refresh or line up cover before that date.
Figure 2. The ACX4000 against 7 other models in Juniper ACX Series. Each bar runs from the earliest milestone Juniper publishes for that model, which is first availability where it gives one and end of sale otherwise, to its last date of support. The vertical rule is today; bars entirely to its left are past support.

Options from here

The Juniper ACX Series ACX4000 is still supported. Options to plan around, in rough priority:

Monitor the timeline

Supported for now. Track the end-of-service date and revisit at refresh planning.

Plan the refresh

Fold the eventual replacement into your multi-year budget.

Keep firmware current

Stay on a supported software train while under OEM support.

Third-party maintenance later

An option to extend life once the OEM cutoff nears.

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.
