Series lifecycle table
Cisco SF550X EOL List
This table tracks end-of-life milestones for 38 Cisco SF550X part numbers. For each record it lists the key dates published in Cisco lifecycle notices: the EOL announcement date, End-of-Sale (EOS), and End-of-Service-Life (EOSL). The Cisco SF550X family has no single end-of-life date; milestones are set per part number, so use the table to find the exact SKU you operate. Across this series, EOSL dates range from 2024-02-29 to 2025-06-30. Open any part number for source details, replacement fields, and current availability options.
