Remove the rear protective access cover to expose the internal SODIMM memory slot. Align the polarization notch on the 2711P-RR256 edge connector with the corresponding ridge in the card socket, insert the module firmly at a 45-degree angle, and press downward until the side retaining clips snap locked. Reinstall the protective cover securely before applying power to the terminal.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":52913947050264,"sku":"2711P-RR256","price":270.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/3483\/3688\/files\/2711P-RR2563_ad2ac42f-bb16-40f7-bdd0-ba732f68e146.png?v=1792116060","url":"https:\/\/www.innoplcsync.com\/products\/allen-bradley-2711p-rr256-ram-module","provider":"InnoPLC Sync Co., Ltd.","version":"1.0","type":"link"}
