Load shedding and ramping is available in Tripp Lite’s Uninterruptible Power Supplies or Power Distribution Units, with controllable outlets. These devices are further classified as either autonomous or non-autonomous.
An autonomous device is capable of storing and executing load shedding and ramping configurations independent of a SNMPWEBCARD or PowerAlert software application running on a PC connected to the device via a USB/serial connection. The following is a list of available autonomous devices.

Configuration of ramping and shedding on PDU devices is supported only through a SNMPWEBCARD.
NOTE: On any autonomous devices utilizing a SNMPWEBCARD, disconnect the network cable before utilizing the RS232 connection on the UPS.
UPS systems that have controllable outlets but not listed above are considered to be non-autonomous. These devices require the presence of a SNMPWEBCARD and only allow for configuration of a load shedding sequence.
The load ramping tab, only available on autonomous devices, allows for the configuration of an outlet ramping sequence that will be applied anytime primary AC power is applied. To enable ramping select and action and a delay for the outlet to wait before turning back on anytime primary AC power is applied. To disable ramping then set all actions to turn on after a delay with a time of zero seconds.
