Under normal circumstances, you will not need to remove the controller from its enclosure. For this reason, the components that you will use most often are conveniently located on the front panel. For example, the maintenance port provides a convenient way to connect a PC or terminal to your controller so that you can interact with it.

After you configure your controller, you should periodically check its control panel. If an error occurs, one or more of the LEDs on the control panel will flash in a pattern that will help you to diagnose the problem. See the HSZ80 Array Controller ACS Version 8.3 Maintenance and Service Guide for details about troubleshooting your controller.

Maintenance Port

You can access the controller in two ways: through a PC or terminal via the maintenance port or through a remote terminal—sometimes called a virtual terminal or host console—via the host. Compaq recommends that you use a PC or terminal to carry out the troubleshooting and servicing procedures in this manual. See “Establishing a Local Connection to the Controller,” page 2–26,for more information about connecting the controller with a maintenance port cable.
