Installation & Operation Manual 47. Troubleshooting Strategy
Problem Possible Cause(s) Actions to Take See:
Media Gateway
board malfunction
Try to repeat lock/unlock action on
the Media Gateway board. Wait up
to 3 minutes for the board to
complete the reboot.
If this does not help, alter the
BoardProvisioningMode parameter
in Media Gateway properties screen
to "MAC Address", set the correct
MAC addresses, and repeat
lock/unlock sequence on the Media
Gateway board.
Do not forget to restore the
BoardProvisioningMode
parameter in the Media Gateway to
"Geographical Address" value
after finishing the troubleshooting.
Even if this troubleshooting helped,
there is no need to keep it
permanently as the Media Gateway
board typically works in
"Geographical Address" mode for
the consequent lock/unlock cycles.
