Troubleshooting the Power and Cooling Systems in the CSACS-1121 Series
Appliance
Both the power LED and the fans can help you troubleshoot a power problem. Check the following items to help isolate
the problem:
When the CSACS-1121 Series appliance is connected to the power source, is the appliance power LED on the front
panel on? If not, check the AC power cord connection; if the power LED is still off, the problem might be due to a
power supply failure.
Does the appliance shut down after being on for only a short time?
—
Check for an environmentally induced shutdown. For more information, see

section.
—
Check the fans. If the fans are not working, the appliance will overheat and shut itself down.
If the fans are not working, you might need to check the power supply connection to the fans.
Checking this connection will require you to shut down the appliance, remove any external cables, and open up the
appliance.
—
Ensure that the appliance intake and exhaust vents are clear.

Check the environmental site requirements in
Does the appliance partially boot, but the LEDs do not light? Check for a power supply failure by inspecting the power
LED on the front panel of the appliance:

—
If the LED is off, see the Cisco Information Packet for warranty information, or contact your customer
service representative.
