7.2.1 Managed UPS connections
A managed UPS is a UPS that is directly connected as a Managed deviceto the console server. It can be
connected by serial or USB cable or by the network. The console server becomes the master of this UPS
and runs a upsd server to allow other computers that are drawing power through the UPS (slaves) to
monitor the UPS status and take appropriate action such as shutdown in event of low UPS battery.
The console server may or may not be drawing power itself through the Managed UPS. When the UPS's
battery power reaches critical, the console server signals and waits for slaves to shut down and powers
off the UPS.
Serial and network connected UPSes must first be connected to, and configured to communicate with the
console server:

& Network > Serial Port
menu, configure the
