3-46 L90 Line Current Differential System GE Multilin3.4 MANAGED ETHERNET SWITCH MODULES 3 HARDWARE33.4.6 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 ÖØ USER-PROGRAMMABLE SELF-TESTS menuand the relevant PORT 1 EVENTS through PORT 6 EVENTS settings under the PRODUCT SETUP ÖØ COMMUNICATIONS ÖØ ETH-ERNET 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 L90will 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 L90 has not detected thepresence of the Ethernetswitch via the bus board.The L90 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 L90.
