Fabric OS 5.0.0 diagnostics and system error messages reference guide 167
FW-1242
Message
Probable cause
The number of EE CRC errors rose above the high boundary. Invalid CRC messages occur when the
number of CRC errors in Fibre Channel frames for specific source ID (S_ID) and destination ID (D_ID)
pairs change. These messages may also be caused by dirty equipment, temperature fluctuations, and
aging equipment.
Recommended action
The CRC error area of the End-to-End Performance Monitor class helps the user tune the fabric. To reduce
CRC errors, experiment with alternative topologies and cabling schemes. Clean equipment, check
temperatures, and replace old hardware.
Severity
WARNING
