IBM has transferred the IBM Ethernet Switch J48E (machine type 4273) and options from the Systems and Technology division, Storage Systems to IBM System x and updated the warranty on the switch from one year to three years. Any existing customers that have purchased this switch will be upgraded to the three-year warranty at no charge.

This switch is designated as customer setup.

High-performance businesses demand high-performance networking solutions. These solutions include a new class of secure, scalable, and always-on enterprise switch that advances the economics of networking by enabling businesses to deploy innovative new technologies that increase revenue and improve productivity. The IBM Ethernet Switch J48E with Virtual Chassis technology combines the compact, pay-as-you grow economics and low power and cooling requirements of stackable switches with the performance, availability, operational ease and port densities of chassis-based platforms to meet the demands of today's high-performance enterprises.
