Series lifecycle table
Cisco ISR 4400 EOL List
This table tracks end-of-life milestones for 70 Cisco ISR 4400 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 ISR 4400 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 2026-11-30 to 2030-01-31. Open any part number for source details, replacement fields, and current availability options.
