GE Multilin D30 Line Distance Protection System 3-493 HARDWARE 3.4 MANAGED ETHERNET SWITCH MODULES3The switch will automatically reboot after a successful firmware file transfer.5. Once the firmware has been successfully uploaded to the switch module, load the settings file using the proceduredescribed earlier.3.4.7 ETHERNET SWITCH SELF-TEST ERRORSThe following table provides details about Ethernet module self-test errors.Be sure to enable the ETHERNET SWITCH FAIL setting in the PRODUCT SETUP USER-PROGRAMMABLE SELF-TESTS menuand the relevant PORT 1 EVENTS through PORT 6 EVENTS settings under the PRODUCT SETUP COMMUNICATIONS ETHERNET SWITCH menu.Table 3–7: ETHERNET SWITCH SELF-TEST ERRORSACTIVATION SETTING (SETAS ENABLED)EVENT NAME EVENT CAUSE POSSIBLE CAUSESETHERNET SWITCH FAIL ETHERNET MODULEOFFLINENo response has beenreceived from the Ethernetmodule after five successivepolling attempts.• Loss of switch power.• IP/gateway/subnet.• Incompatibility between the CPU andthe switch module.• UR port (port 7) configured incorrectlyor blocked• Switch IP address assigned to anotherdevice in the same network.PORT 1 EVENTS to PORT 6EVENTSETHERNET PORT 1OFFLINE to ETHERNETPORT 6 OFFLINEAn active Ethernet port hasreturned a FAILED status.• Ethernet connection broken.• An inactive port’s events have beenenabled.No setting required; the D30will read the state of a generalpurpose input/output port onthe main CPU upon power-upand create the error if there is aconflict between the input/output state and the ordercode.EQUIPMENTMISMATCH: Card XXXMissingThe D30 has not detected thepresence of the Ethernetswitch via the bus board.The D30 failed to see the switch moduleon power-up, because switch won’tpower up or is still powering up. To clearthe fault, cycle power to the D30.NOTE
