Longhorn EOSL: Frequently Asked Questions
What does end of service life (EOSL) mean for Longhorn equipment?
EOSL is the date after which Longhorn no longer sells support contracts or ships updates for a product. The equipment keeps working; only the OEM's willingness to support it ends. Third-party maintenance takes over from that date with engineering support and replacement parts.
Can I get support for Longhorn products that are already past EOSL?
Yes. 8 Longhorn products in this list are already past their EOSL date and all remain supportable. We hold spares for every model we quote and cover equipment for 5+ years past the OEM date.
How far ahead should I plan for a Longhorn EOSL date?
Start 6 to 12 months before the EOSL date. That is enough time to compare the OEM's final renewal against third-party maintenance, decide whether to extend or refresh, and move coverage without a gap. We return an indicative price within 24 hours and a firm quote within 48.
