Diagnostics Tab on page 59.
Traffic Flow
Symptom Explanation and Possible Solutions
Traffic is not being passed Verify that the Host and Network port transceivers (1
Gig and 10 Gig Ethernet Datacryptors only) and the
cables are properly seated.
Use the Ping Peer unit on the Ethernet encryption tab to
confirm connectivity.

Fan/Heat Monitor Alarm
Symptom Explanation and Possible Solutions
Fan/Heat Monitor Alarm Consult the Environment tab on the Properties dialog
for readings of the fan speeds and unit temperature.
Compare these readings to those recorded during
normal operation to determine the nature of the
problem.
Verify that nothing has become inserted in the fan or
ventilation holes which could restrict the fan operation
or airflow. In a normal working environment i.e. setup
in accordance with the
rack mounting instructions the
unit is able to function correctly with a fan or fans
disabled.
If the condition persists then it could indicate that the
temperature is above the level required for reliable
operation and the unit should be returned to Thales for
investigation/Repair.
