• The problem indicates a transient hardware error in MQSS CHIP Fabric output block.
• If the error occurred for the first time , it is recommended to clear the alarm by "clear chassis fpc errors fpc-slot <slot number> all" command(this command do not require MW)and keep monitoring.
• If the error repeated in a short time , it is recommended to reboot/reseat the FPC in MW
• If the error repeated after reboot/reseat , then FPC RMA should be considered.
