Section 3.3:Sysconfig Information
/etc/sysconfig/ups
The /etc/sysconfig/ups file is used to specify information about any Uninterruptible Power
Supplies (UPS) connected to your system. A UPS can be very valuable for a Red Hat Linux system
because it gives you time to correctly shut down the system in the case of power interruption. The
following values may be used:
• SERVER= <value> , where <value> is one of the following:
– yes — A UPS device is connected to your system.
– no — A UPS device is not connected to your system.
• MODEL= <value> , where <value> must be one of the following or set to NONE if no UPS is
connected to the system:
– apcsmart — For a APC SmartUPS™ or similar device.
– fentonups — For a Fenton UPS™.
– optiups — For an OPTI-UPS™ device.
– bestups — For a Best Power™ UPS.
– genericups — For a generic brand UPS.
– ups-trust425+625 — For a Trust™ UPS.
• DEVICE= <value> , where <value> specifies where the UPS is connected, such as
/dev/ttyS0.
• OPTIONS= <value> , where <value> is a special command that needs to be passed to the UPS.
