Extron electronics Quantum Ultra Replacing Manual

Replacing the Quantum Ultra
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 Quantum Ultra User Guide, available at
www.extron.com.
To replace either Quantum Ultra power supply:
