QLS250, QLS450, QLS650, and QLS800 Appliances have a redundant power supply unit (PSU) and
support DC PSUs.
If necessary, you can replace a PSU. Note that all PSUs on an appliance must be of the same type (DC).
Important - Make sure you are electromagnetically grounded before you install,
uninstall, or replace a PSU. ESD (electrostatic discharge) can damage the appliance.
