About this data
Where the specifications on this page come from
Where does the C9500X-28C8D data come from?
The C9500X-28C8D specifications on this page are sourced from Cisco's published datasheets and product documentation. SKUit extracts and normalises those values into its product catalog, the same data its BOM builder uses. This page summarises them; it is not Cisco's datasheet, and the original documents are published by Cisco.
Create a validated BOM with the C9500X-28C8D
SKUit turns a use case into a complete, orderable bill of materials — the right platform, optics, licences and power, reconciled against the same validated data shown on this page.
To create a bill of materials for the C9500X-28C8D, you need to log in or create an account. Log in and you will come straight back to the builder with it selected.
