IBM AS400 iSeries Support

IBM iSeries AS400 Support & TPM Solutions


Many companies still have their original AS400 device in fine working order. Because many of these devices have reached the end of their service life with the manufacturer, third party maintenance solutions may be necessary to keep them in top shape. Resources for these older machines can be difficult to find and sometimes what is available is confusing and difficult to understand. That’s where M Global can step in—our expert engineers have been working with these models for many years and can tailor the procedure to meet the customer needs. Common failures like cache battery replacements and disk failures are easily managed.

What's with all the different names for the IBM AS 400?


The IBM AS400 iSeries has gone through many transformations and name changes since its inception in 1980’s. It began as the AS/400 (Application System/400) in 1988. In the year 2000, it was updated and renamed iSeries. It was again updated in 2006 with a new operating system and renamed Series i. In 2008, the name was changed again to Power Systems and a new operating system was updated.


There has been quite a bit of confusion in all these name changes and updates and it certainly doesn’t help that people often use names interchangeably. For instance, someone may have an iSeries device but use the term “AS400” when searching for information or support. This can make it difficult to find the right information.

Some names associated with the AS 400 iSeries include:

AS400, eservers, iSeries, i Systems, Series i, System i, Power Systems, i5, Power5
