7-12 N60 Network Stability and Synchrophasor Measurement System GE Multilin
7.2 TARGETS 7 COMMANDS AND TARGETS
7
• Latched target message: Yes.
• 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.
• Latched target message: Yes.
• Description of problem: There is a limitation when using six PMUs. The self-test trips when any of the following accept-
able 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
– 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
d) WRONG TRANSCEIVER MESSAGES
Description: The type of SFP does not match the CPU type.
T-type CPU = All ports support fiber SFPs only
Type: minor
Target: latched
Message: "WRONG TRANSCEIVER"
A webpage "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.
e) SFP X MODULE FAIL MESSAGES
Description: A faulty SFP or unplugging the SFP would generate this self test.
Type: minor
Target: self reset
Message: SFP MODULE x FAIL
The webpage "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 FUNC-
TION" setting enables/disables this self test. The target for this self test is priority-based, with the third one being the high-
est 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.
