CU*BASE Network and Hardware Specifications


These guidelines are designed for new credit unions who are converting to the CU*BASE platform with CU*Answers. The standards and guidelines outlined below should be used in the planning process for upgrading existing equipment, for the purchase of software and new equipment, and for preparation of the training site in anticipation of the conversion.


The guidelines are intended to help make the transition smoother and eliminate unnecessary complications and problems that come from untested or incompatible equipment and software. A successful conversion depends on many factors; network configuration, network security, and hardware compatibility are critical components in making sure your staff can reap the benefits of your CU*BASE investment from day one.
