Dell 6248 SFP Troubles
Hello:
I am trying to connect my fiber internet connection to the 6248.
When I run show fiber-fiberports optical-transceiver it shows me the details of the SFP. The SFP is being recognized and It looks like it is seeing good signal, however the port is not coming active. I have tried hard setting the port and swapping the fiber positions. I want to get this resolved asI am currently using a media converter fiber >cat5.
At the moment the fiber is NOT plugged into the SFP but when it is, input dBm goes to ~5 and LOS goes to NO.
Output Input
Port Temp Voltage Current Power Power TX LOS
:emotion-44: [Volt] [mA] [dBm] [dBm] Fault

Hi,
Are you connecting the fiber modem right into the switch or is there a router between the two? It sounds like it is making a link when you have it connected, but have you tried any of the other combo ports or a different SFP transceiver?

The connection I am getting is from a cisco ASR series router. I have tried other combo ports and I also tried cisco SFPs but I don't think they are supported.

If you give the ports IP addresses can they ping each other?

I was working off the status lights for the ports which are not coming on. I can try and set an IP. I wanted to do a Layer2 connection between the fiber uplink from the ASR to a Cat5 connection to my router. Basically, I wanted to use it as a media converter.
