TARGETS MENU
• Description of problem: A link loss detection on an Ethernet port. The link loss is due to unplugging the cable or the
switch port being down.
• How often the test is performed:
• What to do: Check the connection.
WRONG TRANSCEIVER
• Latched target message: Yes.
• Description of problem: The type of SFP does not match the CPU type.
T-type CPU = All ports support fiber SFPs only
U-type CPU = Maintenance port needs RJ45 SFP and the other two ports fiber SFPs
V-type CPU = All ports support RJ45 SFPs only
• What to do: A web page "SFP Transceiver Information" is provided. This page displays the type of the SFP in it. This data
is to be used with the CPU type to know the cause of the problem.
SFP MODULE x FAIL
• Latched target message: No.
• Description of problem: A faulty SFP or unplugging the SFP would generate this self test.
• What to do: The web page "SFP Transceiver Information" described in the previous section applies for this self test as
well. The "SFP Module Fail" has higher priority and it suppresses the "Ethernet Fail" target message. The "SFP MODULE
FAIL FUNCTION" setting enables/disables this self test. The target for this self test is priority-based, with the third one
being the highest priority. For example, if all three SFP modules fail, then the third SFP target is activated. If the third
SFP module failure resolves, then the second SFP target is activated.
Self-Test Error
AGGR CONFIG MISMATCH
• Latched target message: Yes.
• Description of problem: There is a limitation when using six PMUs. The self-test trips when any of the following
acceptable conditions are violated.
– Two aggregators are allowed when using six PMUs, IEEE C37.118, and a 120/100 reporting rate
– One ASDU is allowed when using six PMUs, IEC 90-5, and a 60/50 reporting rate
7
– One ASDU and one aggregator are allowed when using six PMUs, IEC 90-5, and a 120/100 reporting rate
• How often the test is performed: Event driven.
• What to do: Reconfigure aggregators according to the rules, as follows:
– For C37.118 with six PMU software option, the following is acceptable:
a. 20/100 reporting rate: 2 aggregators are allowed
– For 90-5 with six PMU software option, the following are acceptable
a. 60/50 reporting rate: six PMUs can be supported with one ASDU only
b. 120/100 reporting rate: six PMUs can be supported with one ASDU and one aggregator combination only
AUTHENTICATION FAIL
• Latched target message: No.
• Description of problem: The number of failures threshold was exceeded.
• What to do: Wait for the lockout interval and try to authenticate again.
