Cisco Systems 2140 Manual Do Utilizador

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 

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.

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 

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 

.

Ensure that the appliance intake and exhaust vents are clear.

Check the environmental site requirements in the 

.

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.

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
