9500 MXC LEDs
Vol. V-2-10
This section provides information on 9500 MXC front-panel LEDs.
• Each INU/INUe plug-in has one or more tri-color LEDs.
• The IDU has two tri-color status LEDs.
• LED states are resolved using the following descending priority order:
• Red
• Orange flashing
• Green
• Status LEDs indicate green for normal operation, orange flashing for a
configuration problem or diagnostic-mode selection, and red for a critical/
major problem.
• 9500 MXC software updates LED states at least once every second.
• Fleeting LED states are extended by software to ensure that a user has time to
recognize a change in status. A red LED state will remain active for a minimum
of 500 ms.
• A green RAC On-Line LED indicates it cannot be removed without impacting
customer traffic. An Online LED should only be off (unlit) for an offline RAC
in a protected configuration where both Tx and Rx online have been assigned to
the other RAC. (The default configuration has the primary RAC online
transmitting and the secondary online receiving, in which case both RACs will
have a green Online LED).
• At start up, NCC Test and Status LEDs will initially be red, then flashing
orange, until the software can apply the correct states.
• When a plug-in is inserted into a powered INU/INUe, its Status LED will
remain red until software can apply the correct state. Any other LEDs on the
plug-in will remain off until the software can apply the correct states.
• All RAC, DAC and AUX LEDs will remain unchanged during a soft reset until
the software can apply the correct states.
A normal INU/INUe or IDU will have all LEDs green or unlit. All Status LEDs must
be green.
