Configure UPS
The are two options for configuring the RaQ XTR 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 a master (not a RaQ XTR server) over the network
to verify the status of the power supply.
If you configure a RaQ XTR as a master , the RaQ XTR configures itself
automatically. Before choosing this option, you must first connect the UPS to
the RaQ XTR through the serial port; see Figure 98 for the correct serial port.
If you configure a RaQ XTR as a slave, the LCD screen prompts you for the
IP address of the device that is configured as the master.

✍
Note: The RaQ XTR server cannot act as a master for other
machines. Allowing slave access by arbitrary machines would pose
a security risk.
The distinction between master and slave is whether the RaQ XTR
is connected directly to the UPS (a master ) or pointed to another
machine that is connected to the UPS (a slave ).
If you configure the RaQ XTR as a slave , you must have, on the
network, a machine acting as a UPS master that is configured to
allow slave access for the IP address of your RaQ XTR.
