If you intend to run a hard-coded static identity, configure the switches matching your desired 192.168.1.XXX field target range instead.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ3: How do the mechanical shock and vibration specifications impact field enclosure mounting choices?\u003c\/strong\u003e\u003cbr\u003e\nA3: Tested to withstand 5 g vibration (10–500 Hz) and 30 g operational shock, this module is specifically engineered to endure severe factory floor dynamics. This robustness allows it to be safely mounted in distributed junction panels situated directly on high-vibration machinery frames without dropping network frames.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":51050311254148,"sku":"1794-AENT","price":126.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/7454\/7844\/files\/1794-AENTR.jpg?v=1780670101","url":"https:\/\/www.etowonauto.com\/products\/allen-bradley-1794-aent-flex-io-8-slot-ethernet-communication-adapter","provider":"Etowon Auto","version":"1.0","type":"link"}
