Juniper M/MX Series M40 End-of-Life & EOSL Dates

PAST VENDOR SUPPORTJuniper ended support between July 2004 and January 2016, depending on the part number.

Juniper M/MX Series M40 — router. Published end-of-sale (last order) and end-of-support (EOSL) dates from Juniper JTAC End-of-Life bulletins.

Every tracked Juniper M/MX Series M40 SKU group is past Juniper end of service life (last group Jan 2016). Units in production should be treated as unsupported. For past-EOSL units, weigh third-party maintenance, spares, replacement, or a documented run-to-failure.

Figure 1. Support ended between Jul 2004 and Jan 2016, depending on the part number. 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.

Run to failure
