Cisco Systems 2140, 2130 manual Troubleshooting the Power and Cooling Systems

Appendix A Troubleshooting

Problem Solving

Note The LEDs on the front panel of the appliance enable you to determine appliance performance and operation. For a description of these LEDs, see the “Reading the LEDs” section on page A-5.

When problem solving, check the following appliance subsystems first:

•Power and cooling systems—External power source, AC power cable or DC power wires, and appliance fans. Also check for inadequate ventilation, air circulation, or environmental conditions.

•Adapter cards—Checking the LEDs on the adapter card can help you to identify a failure.

•Cables—Ensure that the external cables connecting the appliance to the network are all secure.

Troubleshooting the Power and Cooling Systems

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 Cisco ADE 2130 and 2140 Series appliance is connected to the power source, is the appliance power LED on the front panel on?

–If not, check the connection of the AC power cord or DC power wires.

–If the power LED is still off, the problem might be a power supply failure.

•Does the appliance shut down after being on for only a short time?

–Check for an environmentally induced shutdown (see the “Environmental Reporting Features” section on this page).

–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 connections to the fans.

Checking this connection will require you to shut down the appliance, remove any external cables, and open up the appliance. For more information, see the “Removing the Cover” section on page 4-3.

–Ensure that the appliance intake and exhaust vents are clear.

–Check the environmental site requirements in the “Temperature and Humidity Guidelines” section on page 2-9.

•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 on, the power supply is functional.

–If the LED is off, refer to the Cisco Information Packet for warranty information or contact your customer service representative.

Environmental Reporting Features

The Cisco ADE 2130 and 2140 Series appliance has protection circuits that monitor and detect overcurrent, overvoltage, and overtemperature conditions inside the appliance. If the power supply shuts down or latches off, an AC cycle of off for 15 seconds and on for 1 second resets the power supply. For more information, see the “Environmental Monitoring” section on page 1-16.
