WRONG TRANSCEIVER
•
Latched target message: Yes.
•
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 T60 to no power information for the T60 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.
