Troubleshooting Sentry Unix
We have made every effort to ensure an easy and straight forward Sentry installation. If you should experience problems or unexpected results during the installation or execution, please verify your system setup and configuration using the following checklist:
- Positively identify the serial port to which the UPS interface cable is connected. (Consult computer and/or operating system documentation if necessary.)
- Verify that no other hardware or software is using/accessing this serial port, including your mouse. Sentry requires a serial port dedicated to monitoring the UPS.
- Verify that you are using the UPS interface cable supplied with the Sentry software and that it is securely connected to the serial port.
- Verify that the other end of the supplied cable is securely attached to the UPS interface port. This end should not require any adapters.
