ETEP Installation Guide

When the ETEP enters an alarm state due to a temperature failure, the Alarm indicator illuminates and 
the ETEP discards traffic. The ETEP remains in an error state until it is rebooted. However, once the 
temperature drops below the critical threshold, the alarm indicator turns off and the ETEP stops reporting 
an alarm state to ETEMS, even though the alarm state has not been cleared and the ETEP continues to 
discard traffic. 

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. 

The Alarm LED is illuminated

The ETEP enters an error state when a boot test fails, the 

operating temperature threshold is exceeded, signature errors are 

detected on critical files pertaining to policies and keys. or a FIPS 

test fails when the ETEP is in FIPS mode. 
When the ETEP is in an error state the Alarm LED illuminates, and 

the appliance discards all packets it receives. Depending on the 

error, other notifications may be sent (traps, status messages to the 

ETEMS or the terminal). 
To recover from an error state when FIPS mode is disabled:
• When the ETEP detects a corrupted policy, it enters an error 

state and sends a critical error trap to the management station. 

To recover, redeploy the policies and then reboot the ETEP.

• For non-policy errors, reboot the appliance. If the operating 

temperature threshold is exceeded, cycle the power to restart 

the ETEP. 

• If a failure occurs during the boot process, refer to 

 for additional troubleshooting 

information.

• If the actions listed above do not clear the error, contact 

customer support.

To recover from an error state when the ETEP is in FIPS mode:
• A FIPS test failure or signature error will cause the ETEP to 

zeroize. To learn more about the zeroization process and 

recovery from that state, see
