The FCU module uses part number AUA24 and is intended to be installed in the FCU slot in the upper shelf of the system, where it interfaces with the unit’s cooling fans. A maintenance note documented with AT\u0026amp;T references the FAN TEST procedure: pressing the FAN TEST button on the FCU should cause the fans to operate during testing, and the FCU is commonly acquired as a used replacement component for refurbishment of aging telecom infrastructure.\u003c\/p\u003e\u003c\/div\u003e","brand":"AT\u0026T","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51660303663406,"sku":null,"price":197.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_de75806d-1ae7-4ef8-9947-03c73d3accf2.jpg?v=1769535868","url":"https:\/\/plgautomation.com\/products\/industrial-5scd500axx-fan-control-unit-module-card-circuit-board","provider":"PLG Automation ","version":"1.0","type":"link"}
