Power Controller Introduction
Digi CM User Guide 121
Introduction
The Power Controller feature allows the administrators of the Digi CM unit to use console
management to control power functions. Power control consists of three basic functions: on, off,
and reboot (power cycle). There are two typical scenarios when using a power controller. The
simplest scenario is a non-serial device connected to a power controller (for example, an
environmental sensor controller or a tape backup device). The power controller is configured and
accessed through the Digi CM unit.
This illustration shows the a power controller configured through the Digi CM unit for non-serial
devices.
The second scenario is a serial device (such as a router or server) managed through a port on the
Digi CM unit with its power supply mapped through the power control feature. After configuration is
complete, you need only reference the console management port on the Digi CM unit to also
manage power. The Power Controller feature handles the relationship of a specific outlet to a serial
device as if the power supply was also connected to the same port as the serial device. In other
words, you don’t need to see the physical connection or remember which outlet controls a specific
serial device after configuration - the Digi CM unit does that for you.
The following illustration shows a Sun server configured through a serial port connection on the Digi
CM 32.
