Each UPS was tested driving a single Apple Dual xServe G5 400W server and an 80W monitor. The basic routine was:
- Charge up UPS batteries.
- Connect server to the UPS.
- Cut mains supply and start Linux timing script.
- Timing script writes timestamp to file every minute.
- Wait for battery to run down.
- Reconnect mains and reboot server.
- Check time-stamp file for the total minutes of operation.
