The following tables provide some solutions to common problems that may occur with your ETEP.

No power light.

• Make sure the power cable is attached and plugged in to both 

the device and the power outlet.

Alarm light is lit.

• The ETEP is in an error state. See 

 for 

information about possible causes and recovery procedures. 

Port status LED is off (no link). 

• Check the network cable. Verify correct transmit and receive 

cable polarity.

• Check the operational status of the equipment being connected.
• Verify that the auto-negotiation and flow control settings on the 

local or remote port in question match the settings of the 

equipment to which they are connected.

• If the problem is not resolved, the network may not be 

functioning properly. Consult a local network administrator.

Port status LED is not blinking 

(no traffic).

• Check physical connectivity. 
• Verify that the policies are set up to allow traffic to pass through 

the appliance. 

• Check with your Network Administrator to ensure proper 

placement in the network.

Power supply LED is off

The power supply is unplugged or is unable to recover from a 

power interruption.
• Make sure the power cable is attached and plugged in to the 

power supply and the power outlet.

• Check the status LED on the power supply on the rear of the 

unit. If the LED is off, the power supply is not receiving power. If 

the LED is red, the power supply requires a manual power 

cycle. Unplug the power cord, wait 5 seconds, and then reapply 

power. The LED is green during normal operation. If a manual 

power cycle does not restore power, contact customer support.
