Worried about the following error-message while plugging in a TwinGig Converter Module (CVR-X2-SFP) in a Catalyst 4500?
%C4K_TRANSCEIVERMAN-3-SEEPROMREADFAILED: Failed to read transceiver serial eeprom on port Te5/3, try reinserting
This is really not a serious problem although it looks like one. You just have to configure your TenGigE-Port to GigE. On a 6Port 10GE-Linecard (WS-X4606-X2-E) it is important, that you can only put 3 ports in 1GigE-Mode at once. Each 3 Ports are grouped together to one Port-Group. If this is a problem you can deal with the TenGigE-Ports on your Sup (depending on the Sup you are using…)
You can have the following configurations on a WS-X4606-X2-E:
- 6 TenGigE
- 3 TenGigE, 6 GigE
- 6GigE, 3 TenGigE
- 12 GigE
To switch a Port-Group over to 1 GigE use the following command:
hw-module module 5 port-group 1 select gigabitethernet
This will put your 1st three ports on the Module in Slot 5 into Gigabit-Mode and voila – your TwinGigConverterModule will no longer be rejected with this crazy errormessage.
