Options from here

Unsupported now

The Juniper T Series T640 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 or maintenance and lists no paid placements. Third-party maintenance keeps unsupported gear in production past the OEM cutoff; whether it fits depends on the asset's role.
