ES violations threshold crossing alert for section layer at local NE. A one second interval in the transmission from the far end originating NE has had an error at the section layer causing an Errored Second Section (ESS). ESS errors have exceeded the user definable threshold level.
Errored seconds threshold crossing alert for reported port.
Excessive Bit Error Rate count.
Cell bus hard failure.
Check input levels and signal sources. Increase threshold settings if necessary. Check local requirements for proper levels.
Check input levels and signal sources. Increase threshold settings if necessary. Check local requirements for proper levels.
Applies to all SONET cards.
Each of these alarms indicate a switch fabric failure. Check alarm messages, is the failure on both buses? One card? All cards? If single card failure, remove from backplane, check pins in backplane connector, and reseat. One card failure could pull down the entire bus. Pull each card out one at a time starting with protect, check the pins in the backplane connector, monitor system traffic for recovery, then reseat the card. Perform switch over via GUI or craft interfaces before pulling EIMs if necessary. Do not pull the working cards. Repeat procedure for SC TEIM in slot 18 at the rear of the shelf. This is a bus termination and the system will crash without it.
