Monitoring Sfps - Dell Force10 S2410-01-10GE-24P Configuration Manual

Monitoring SFPs

The four fiber ports on the S50 and S50V share the interface numbers 45, 46, 47, and 48 with the
corresponding copper ports. Only the fiber port or the copper port can be active at any given point in time.
The fiber ports take precedence over the copper ports — if the S50 detects good links through both copper
port 48 and fiber port 48, it will bring up the fiber port's link and bring down the copper port's link. The
copper port will become active automatically if SFTOS detects a link down condition on the associated
fiber port.

If a fiber port does not come up, use the following troubleshooting steps:
1. Verify you are using the correct SFP type, such as SR or LR. Optical specifications are available on the
Dell Force10 website:
2. Reseat the SFP or swap it with a known good one.
3. Use a different pair of fiber cables, or at least verify that fiber end faces are clean. Clean the optical
transceivers at both ends, as described in
www.pxit.com/pdf/whitepapers/Cleaning&Inspecting.pdf).
Note: The Dell Force10 quality assurance team has verified cases in which a fully functional
port appears to be a bad port due to dirty optical connectors. The port fails loop testing with
acceptable power measurement levels.
Note: Dell Force10 recommends closely following the instructions in the referenced document
on cleaning the optics.
