The 16‑port 10G capability is realized with the DFC4‑E card installed, expanding the module to a 16x10G fiber card in addition to its native four 40G uplinks. This module is designed for Cisco Catalyst 6500 Series switches and supports deployment on appropriate chassis with the correct supervisor; specifically, WS‑X6904‑40G‑2T is documented as supported only with WS‑C6503‑E hardware revision 1.3 or higher. Each 40G port uses a fiber interface for high‑speed uplinks, while the 10G ports (via the DFC4‑E) provide flexible downlink connectivity to servers, storage, or distribution\/access layer devices. In practical terms, this card enables a compact 40G core connection footprint alongside a dense pool of 10G links, suitable for environments requiring scalable, multi‑rate fiber connectivity within Cisco’s Catalyst ecosystem. \u003c\/p\u003e\u003c\/div\u003e","brand":"Cisco","offers":[{"title":"New","offer_id":51678092165422,"sku":null,"price":428.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_6592fc9c-b03c-4d8e-a0c1-f1b493a3fc6f.jpg?v=1769571628","url":"https:\/\/plgautomation.com\/products\/cisco-ws-x6904-40g-2t-4-port-40g-16-port-10g-fiber-card","provider":"PLG Automation ","version":"1.0","type":"link"}
