Replacing the Quantum Ultra

Power Supplies

The Quantum Ultra has a primary and a redundant power supply unit (PSU) to ensure continued,

uninterrupted operation if a power supply should fail. However, if a power supply does fail, you should replace it as soon as

possible. The power supplies are hot-swappable, that is, one can be replaced while the unit is operating with the other PSU

supplying power.

NOTE:For full installation, configuration, and operation details, see the , available at Quantum Ultra User Guide

www.extron.com.

protective cover panel (see gure 1,

• Thumbscrews should be tightened with a tool after both initial installation and subsequent access to the panel.
