TARGETS MENU
• Description of problem: The type of SFP does not match the CPU type. The SFP is a silver device that plugs into the rear
of the CPU module.
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
The consequence of an incorrect SFP can range from damage to the B90 to no power information for the B90 on its
web page (enter IP address in a web browser, then click the SFP Transceiver Information. Only the type of SFP
displays and not power data).
• 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 small form-factor pluggable port (SFP) or unplugging of the SFP generates this self test
message.
• 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.
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.
FIRMWARE LOCK
• Message: "Unauthorized firmware attempt"
• Latched target message: No.
7
• Description of problem: A firmware upgrade operation was attempted while the lock relay setting was enabled.
• What to do: Ask the Supervisor to unlock the relay and try again.
SETTING LOCK
• Message: "Unauthorized setting write"
• Latched target message: No.
• Description of problem: A setting write was attempted while the lock relay setting was enabled.
• What to do: Ask the Supervisor to unlock the settings and try again.
SERVER UNAVAILABLE
• Message: "An attempt to contact the Radius server has failed"
• Latched target message: No.
• Description of problem: The RADIUS authentication server is unavailable.
• What to do: Verify network connectivity and try again.
