IBM Electronic Services

IBM has transformed its delivery of hardware and software support services to put you on the road to higher systems availability. Electronic Services is a Web-enabled solution that provides an exclusive, no-additional-charge enhancement to the service and support available on the IBM eServer® platform. These services provide the opportunity for greater system availability due to faster problem resolution and preemptive monitoring. Electronic Services comprises two separate, but complementary, elements: IBM Electronic Services news page and IBM Electronic Service Agent™.

Electronic Services news page is a single Internet entry point that replaces the multiple entry points traditionally used to access IBM Internet services and support. The news page enables you to gain easier access to IBM resources for assistance in resolving technical problems.

The Electronic Service Agent is no-additional-charge software that resides on your IBM eServer system. It monitors events and transmits system inventory information to IBM on a periodic, customer-defined timetable. The Electronic Service Agent tracks system inventory, hardware error logs, and performance information. If the server is under a current IBM maintenance service agreement or within the IBM warranty period, the Service Agent automatically reports hardware problems to IBM. Early knowledge about potential problems enables IBM to provide proactive service that may result in higher system availability and performance. In addition, information collected through the Service Agent is made available to IBM service support representatives when they help answer your questions or diagnose problems.
