This plate covers any slot that is not yet populated with a FOX3 I\/O 88 board, sealing the opening so the switcher's fans pull air across the populated boards as designed rather than short-circuiting through an open bay. It is a simple, tool-installed panel with no active electronics.\u003c\/p\u003e\n\u003ch3\u003eKey Capabilities\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSingle I\/O slot coverage, matches the FOX3 Matrix modular board opening\u003c\/li\u003e\n\u003cli\u003eMaintains designed front-to-rear cooling airflow across populated boards\u003c\/li\u003e\n\u003cli\u003eKeeps unused bays sealed during staged or partial deployments\u003c\/li\u003e\n\u003cli\u003eTool-installed captive panel screws, no electronics or configuration required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhere It Is Used\u003c\/h3\u003e\n\u003cp\u003eIntegrators specify this plate whenever a FOX3 Matrix 560x or 840x ships or is commissioned with fewer than 40 I\/O boards installed, and again any time boards are removed for service and the bay will sit open for more than a few minutes.\u003c\/p\u003e\n\u003ch3\u003eSpecifications at a Glance\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCompatibility: FOX3 Matrix 560x and FOX3 Matrix 840x chassis\u003c\/li\u003e\n\u003cli\u003eFunction: single I\/O slot blank\/filler panel\u003c\/li\u003e\n\u003cli\u003eInstallation: tool-installed captive panel screws\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eExtron's own setup documentation for the FOX3 Matrix Series states that boards or blank panels should be installed in all locations during normal switcher operation, making this plate a required accessory rather than a cosmetic option on any partially populated frame.\u003c\/p\u003e\n\u003cp class=\"alt-refs\"\u003eAlso referenced as Extron FOX3IOBlankPlate, FOX3-I-O-Blank-Plate, part number 70112101.\u003c\/p\u003e","brand":"Extron","offers":[{"title":"Default Title","offer_id":52302255980764,"sku":"EXTRON-FOX3IOBLANKPLATE-70112101","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0754\/5582\/4092\/files\/extron-fox3-i-o-blank-plate-70-1121-01.jpg?v=1787221432","url":"https:\/\/www.ampronix.com\/products\/extron-fox3-i-o-blank-plate-70-1121-01","provider":"Ampronix","version":"1.0","type":"link"}
