FLS-A901-4= Overview
FLS-A901-4= Four Flexible GE Port Paper License
FLS-A901-4= is the paper-license spare for the Cisco ASR 901 Gige4portflexi feature. Cisco describes it as a four flexible-port Gigabit Ethernet upgrade for supported 10-Gigabit ASR 901 models. It is a software entitlement, not a router or interface module, and it must not be confused with the SFP-only FLS-A901-4S= license.
Validate the 10-Gigabit chassis family
Cisco maps this license to A901-6CZ-FT-A, A901-6CZ-FT-D, A901-6CZ-F-A and A901-6CZ-F-D. The feature applies to copper and SFP ports 0 through 3 and 8 through 11 on those platforms. Verify the exact chassis PID, hardware revision and IOS license support before purchase; it is not a generic four-port entitlement for every ASR 901.
Reconcile delivery and activation
The equals suffix denotes the spare paper form. Confirm the PAK is unused, retain purchase and assignment evidence, and document the bound router serial after activation. L-FLS-A901-4= is the separately identified electronic-delivery equivalent. Neither form supplies optics, copper cabling, a chassis or additional physical connectors.
Legacy deployment decision
The ASR 901 family and physical upgrade license have reached end of sale, and Cisco's lifecycle notice names no replacement for this PID. Procurement should be limited to a verified installed-base requirement with a tested configuration backup and a migration plan for the router and enabled services.
Official evidence: Cisco exact feature, ports and chassis map, Cisco ASR 901 port-upgrade table and Cisco end-of-sale record.
