Nortel Networks 553-3001-211 manual System DISABLED-OVERLOAD

NT6D80 MSDL card Page 413 of 894

SYSTEM DISABLED—OVERLOAD

Cause: 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.

Action:

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 page 404. If the problem persists, place the card in the manually disabled state by the DIS MSDL x command and follow the steps in “Previously operating MSDL cards” on page 408.

SYSTEM DISABLED—RESET THRESHOLD

Cause: 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.

Action:

Place the card in the manually disabled state with the DIS MSDL x command and follow the steps in “Previously operating MSDL cards” on page 408.
