As part of Ciena’s NTK family of shelf hardware, this module works alongside the shelf processor\/control and DC power input cards to supervise and coordinate the power subsystem that energizes the 6500 shelf in carrier deployments. In typical 6500 configurations, DC-powered shelves rely on dedicated NTK modules to enable reliable power distribution within the modular shelf backplane, a design approach documented in Ciena’s 6500 product family materials and data sheets. The NTK 55522E503 designation identifies this particular DC power shelf control module used in 6500 2-slot shelf assemblies, distinguishing it from other NTK components used across different shelf types and configurations. Public references to 6500 hardware catalogs and secondary-market listings consistently link 55522E503 with 2-slot DC-powered shelf configurations, underscoring its role as the DC power management element within the platform’s power architecture. \u003c\/p\u003e\u003c\/div\u003e","brand":"Ciena","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51678048420142,"sku":null,"price":218.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_ac85d7d1-16aa-41a1-bb22-f8bd9a1b98c7.jpg?v=1769571091","url":"https:\/\/plgautomation.com\/products\/ciena-ntk-55522e503-dc-power-shelf-control-module","provider":"PLG Automation ","version":"1.0","type":"link"}
