16 matching records. Sources checked 2026-10-01.

Note: Hardware support and firmware/software support are separate. A supported firmware release does not extend an appliance's hardware support. A blank milestone means no date captured in this source, not support forever. Check the official source and your contract before an upgrade or purchase.

How to use these lifecycle records

Does a firmware support date mean my appliance is supported?

No. Check both the hardware model and the installed firmware train. Hardware notices can end technical support, replacement and updates before a software train's general deadline.

Is this the complete vendor catalog?

No. This pilot includes only the named models and release rows from its linked official notices and tables. Missing models or versions must be checked with the vendor.

What does an unknown date mean?

No date was captured in the linked source. It is not a promise of continued support. Dates can change, and a source's release-status label may not reflect every support milestone.
