Nortel Networks Circuit Card Manuel D’Utilisation

 NT6D80 MSDL card

The system received an excessive number of messages from the 

MSDL card in a certain time. If the card invokes overload four times in 
30 minutes, it exceeds the recovery threshold as described in “SYSTEM 
DISABLED—RECOVERY THRESHOLD.” The system resets the 
card, invokes self-tests, and attempts to enable the card. The problem 
may be due to excessive traffic on one or more MSDL ports. Traffic load 
redistribution may resolve this condition.

:

Check the traffic report, which may indicate that one or more MSDL 
ports are handling excessive traffic.

By disabling each port, identify the port with too much traffic and 
allow the remaining ports to operate normally. Refer to 
“Maintaining the MSDL” on 

. If the problem persists, place 

the card in the manually disabled state by the 

 command 

and follow the steps in “Previously operating MSDL cards” on 

.

The system detected more than four MSDL card resets within 10 

minutes. The system attempts to enable the card again at midnight unless 
you intervene.

Place the card in the manually disabled state with the 

command and follow the steps in “Previously operating MSDL 
cards” on
