Alarm and Inverter Logs
Your FERRUPS UPS makes an entry in its logs every time it sounds an
alarm or switches to inverter (battery power). This information can be
helpful in diagnosing problems.
You can view the Alarm and Inverter Logs from either the UPS control
panel or a terminal or computer that you have connected to the RS-232
port (see “Connecting a Terminal or Computer to the RS-232 Port” on
page 41).
