Symptom

Explanation and Possible Solutions

LEDs

Power LED is off.

• Make sure the power cable is attached and plugged

in to both the device and the power outlet.

Failure LED is illuminated.

• The device diagnostics detected a severe hardware

error during the boot process. Contact SafeNet

Customer Support.

Alarm LED is illuminated.

• The device has detected a policy configuration

error. Edit the recently modified policy to correct the

problem.

Alarm LED is flashing.

• The HA4000 is loading software. The boot process

is in progress.

Link LEDs are off.

• 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 those on the switch or router. See “Set the

Remote Port Auto-Negotiation and Flow Control”

on page 20 and “Layer 2 MAC Address Resolution”

on page 27.

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

be functioning properly. Consult a local network

administrator.

No flashing traffic lights.

• Check physical connectivity. The HA4000 is not

receiving traffic.

• Verify that the policies are set up to allow traffic to

pass through the unit.

• Check with the Network Administrator to ensure

proper placement in the network.

Log on

Administrator password is

forgotten or lost.

• Contact SafeNet Customer Support.

Not able to log in to the CLI.

• Verify the password.
