0390 - Illegal Address Error

This message indicates an HMUX (High Speed Multiplexer) illegal address error. The ATH (Application Trouble Handler) displays this alarm when an HMUX-assigned shelf ID address, which was received from OAM and written to the Assigned Shelf Address Register, did not match the value read from the Assigned Shelf Address Register. Furthermore, the error was not corrected after an automatic attempt to correct the address discrepancy.

** 0012.0390  **  CARD 1109 HMUX Illegal Address Error 

Alarm Level: Major

Recovery

1. Reset the HMUX card in question by entering the command:
   init-mux:loc=xy09 (or loc=xy10)

   This command resets the card, but it does not take down the IMT bus on which the card resides; operation of the bus is unaffected by this command.

2. If the problem persists, then you should reseat the HMUX card in question.
   Remember that this action will take down the IMT bus of the HMUX card.
3. If the problem remains, the card must be replaced.
