Designed for use with M\/N 57C413B and 57C423 processors, it is typically installed in slot 0 of a rack to serve as the bus arbiter and memory backbone for the backplane. To preserve its contents during power loss, the module requires an external battery backup (57C492). The 0-57423-E designation is the cross-reference for the 57C423 Common Memory Module, a configuration commonly listed in Automax literature and reseller catalogs for Reliance Electric systems.\u003c\/p\u003e\u003c\/div\u003e","brand":"Reliance","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51708581445934,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_8c8d01d3-13bb-4b4e-bad5-37bd10e9c93b.jpg?v=1770246455","url":"https:\/\/plgautomation.com\/products\/reliance-0-57423-e-common-memory-module-128k","provider":"PLG Automation ","version":"1.0","type":"link"}
