If your hardware is on this list
An end-of-service-life date is a planning fact, not an outage. The equipment keeps working past the date; what stops is vendor support: security patches, software maintenance, replacement hardware and TAC. The realistic paths, in the order most teams weigh them:
Replace on your schedule
Budget the refresh into the right quarter above. Where the vendor has named a successor it is listed in the table and linked, with its own lifecycle page, from each product page.
Third-party maintenance
Independent providers keep hardware running past the vendor date with break/fix, spare parts and on-site SLAs, usually below the last OEM renewal quote. It does not restore firmware or security patches; only the manufacturer ships those. What TPM covers, and what it does not.
Pre-stock spares
Buy spares while units still circulate and self-maintain. Pairs well with TPM for gear where a same-day part matters more than a contract.
Run to failure, documented
A deliberate choice for non-critical, easily replaced, well-segmented gear: record the risk, harden monitoring and backups, retire on your terms.
For internet-facing or compliance-scoped equipment, weigh the unpatched-vulnerability exposure first: 6 products on this list carry a CISA known-exploited vulnerability.
Work this list against your own inventory
Paste part numbers or drop a CSV into the bulk checker; it runs in your browser and returns each part's dates and source. Subscribe to the EOSL calendars to get these dates as events, or follow the change ledger for new announcements the week they appear.
2015 end-of-life questions
What hardware goes end of life in 2015?
EOSL.ai tracks 37 product families with 170 part numbers reaching their manufacturer's last date of support in 2015, across 9 vendors. The largest sets are Fortinet (11 products), IBM (9 products), Calix (6 products). Every date on this page links to the vendor's own end-of-life bulletin.
Does hardware stop working at end of service life?
No. The equipment keeps running. What ends is manufacturer support: security patches, software maintenance, hardware replacement and TAC cases. The risk grows over time rather than arriving on the date, which is why the realistic responses are planning moves rather than emergencies.
What are the options when hardware reaches EOSL?
Replace it on your schedule, keep it running under third-party maintenance (hardware support only; security patches still end), pre-stock spares and self-maintain, or run non-critical gear to failure with the risk documented. The support options guide covers each path and how to choose per box.
Where do these 2015 dates come from?
Every date is read from the manufacturer's own published end-of-life bulletin, and each product row links to that bulletin so you can verify it at the source. Records show when they were last re-checked.
