5. Connect the power supply to a power source. If connecting all power supplies, plug separate
power cords into the power supplies and connect them to separate wall sockets.
Note: SD-WAN 4000/5000 appliances emit a high-pitched alert if one power supply fails or if you
connect only one power cable to an appliance in which two power supplies are installed. To
silence the alarm, press the small red button on the back panel of the appliance. The disable
alarm button is functional only when the appliance has two power supplies.
Replacing a DC Power Supply
Replace a DC power supply with another DC power supply. All power supplies must be of the same
type (AC or DC).
Note: You can replace one power supply without shutting down the appliance, provided the
other power supply is working.
