Switched Rack PDU

Purpose and benefits of outlet groups

By using groups of synchronized outlets on Switched Rack PDUs, you can ensure that

outlets turn on, turn off, and reboot in a synchronized manner. Synchronizing control

group actions through outlet groups provides the following benefits.

• Synchronized shutdown and startup of the power supplies of dual-corded servers

prevents erroneous reporting of power supply failures during a planned system

shutdown or reboot.

• Synchronizing outlets by using outlet groups provides more precise shutdown and

restart timing than relying on the delay periods of individual outlets.

• A global outlet is visible to the user interfaces of the Switched Rack PDUs to which it

is linked.
