Fixed AC Power Supply

The Cisco 170 series appliance ships with one fixed power supply (AC) installed. You cannot add
additional power supplies or remove the installed AC power supply. Removing the only power supply
causes an immediate power loss.
There is not an input switch on the faceplate of the power supply. The power supply is switched from
Standby to ON by way of a appliance STANDBY/ON switch.
The AC power supply provides 400 watt output power. The AC power supply operates between 85 and
264 VAC. The AC power supply consumes a maximum of 471 W of input power.
Note If your power supply is non-operational, please contact Cisco Technical Support. See the “Contacting
Service and Support” section on page 4-3 for more information.
