4. Correct Unit Configuration: Units must be configured properly, according to the network plan.

Configuration errors can cause an inability to communicate or poor performance. The addition of
units or other changes to your system may require you to change configuration settings.

5. Embedded Software: Operate with a proven software image. Download new software if you suspect

that a unit’s software is corrupted. Software images are available from the EION, Inc. website:
