Configuring an uninterruptible power
supply (UPS)
The are two options for configuring the RaQ 3 for a UPS: as the master
or as a slave.
The master communicates directly to the UPS through the serial port.
The slave (or slaves) communicates with the master to verify the status
of the power supply.
To configure a RaQ 3 as the master, you must first connect the RaQ 3 to
the UPS through the serial port.
If you configure a RaQ 3 as the master, the RaQ 3 configures itself
automatically. If you configure a RaQ 3 as a slave, the LCD screen
prompts you for the IP address of the RaQ 3 that is configured as the
master.
First, connect the UPS unit and the RaQ 3. (For more information, refer
to the UPS manual.)
1. Plug the UPS into the wall socket.
2. Turn on the UPS.
3. Plug the RaQ 3 units into the UPS power sockets.
4. Connect the the UPS serial cable to the UPS unit and the RaQ 3 that
will serve as the master. See Figure 42 for the correct serial port.
IMPORTANT: You must use the serial cable shipped with the
UPS unit.
