APPENDIX A: INSTALLING AN UNINTERRUPTIBLE POWER SUPPLY
You should connect each unit to a UPS (not supplied). UPS units maintain a limited amount of backup battery power if the main power fails.
To connect communication and power from the UPS to the unit (refer to Figure 20):
1. Shut down the unit if it is on.
2. Connect a power cord from the unit power supply to a standard wall socket.
3. Connect a power cord from the UPS to a standard wall socket or other power source.
4. Connect a USB cable from the UPS to a USB connector on the unit.
5. Power up the UPS.
6. Power up the unit (refer to Startup and Shutdown on page 22 for more information).
Figure 20. Connecting a UPS
WARNING: While most UPS units can be used to supply backup battery power it is recommended that you connect the unit to a SmartUPS
from APC. The SmartUPS signals the unit to begin a graceful shutdown if the standby power in the UPS falls below a certain threshold.
