Extreme 210 fiber port not connecting

Question

Let me preface my question by saying I'm not a network admin and don't know nearly enough about networking.

I have an Extreme 210-12p-GE2 switch.

My problem is that the fiber port that was working is now not working. I had to temporarily disconnect the fiber as I was moving cables around to clean up the physical routing of the cables around the server rack. I have plugged it back in, but it isn't passing any signal through it.

I have figured out a little of the CLI commands and have found this information about the port:

(Extreme 210) #show fiber-ports optical-transceiver-info all

                         Link Link                                 Nominal
                       Length Length                                   Bit
                         50um 62.5um                                  Rate
Port     Vendor Name      [m] [m]  Serial Number    Part Number     [Mbps] Rev  Compliance

So, it is showing that it is plugged in, but it's not passing any traffic or showing that it is active.

My questions are:

1. Did I break something when I disconnected the cable?
2. How do I get the switch to start passing traffic again?

(Extreme 210) (Interface 0/14)#show fiber-ports optical-transceiver all

                                    Output    Input
Port      Temp  Voltage  Current     Power    Power   TX     LOS

0/14      39.5    3.330     28.6    -5.962  -40.000   No     Yes

This last column, LOS, does that mean that the switch isn't sending a signal or that it isn't receiving a signal from the switch at the other end?

Answer 1

With Link Status down and Admin Mode enabled, I'd say the cable is either not fitted correctly or damaged.

I'd try reseating the SFP module and replugging both ends. Check the cable for excessive bending (<10x diameter) or even kinks. Also check the jacks and end faces for any sign of dirt - they need to be immaculately clean. If that doesn't help try another cable.

You could also check for light on -SX/-SR modules (850 nm) using a digital camera, but that seems to be an -LX module where the wavelength (1310 nm) is out of a digicam's scope.

If there are multiple fiber patches and you might have mismatched the cable: you need to use a single-mode cable (usually with a yellow sleeve) with -LX. Orange, aqua or green cables indicating multi-mode fiber won't work.

Also, the endfaces of connector and terminal need to match: either UPC (blue or grey) or APC (green) are used with single-mode fiber. They cannot be mixed.

Answer 2

This is going to seem dumb, but I finally got this working.

I had to go to the other end of the fiber cable. I found that it was the port on the other switch, also an Extreme 210 (210-24p-GE2), was in D-Disabled state.

I can find no way to reset the port other than rebooting the switch. So I made sure the config was saved and rebooted. When the switch came again all was good.
