8.2 Uninterruptible Power Supply (UPS) Control

All Tripp Lite console servers can be conﬁgured to manage locally and remotely connected UPS hardware using Network UPS

Tools.

Network UPS Tools (NUT) is a group of open source programs that provide a common interface for monitoring and

administering UPS hardware to ensure safe shutdowns of connected systems. NUT is built on a networked model with a

layered scheme of drivers, server and clients (refer to 8.2.6 Overview of Network UPS Tools).

8.2.1 Managed UPS Connections

A managed UPS directly connects as a managed device to the console server. It can be connected by serial cable, USB cable,

or the network. The console server becomes the Primary unit of this UPS and runs a upsd server to allow other computers

that are drawing power through the UPS (Secondary units) 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 through the managed UPS. When the UPS battery power reaches a

critical point, the console server will signal and wait for Secondary units to shut down before powering off the UPS.
