The Apple Copper Fibre Channel Cable (SFP-SFP) may have intermittent connection issues if it isn't installed correctly between the Fibre Channel switch and Apple Fibre Channel PCI card in the host computer.
This may happen when using:
- Xserve RAID (SFP)
- Apple Copper Fibre Channel Cable (SFP-SFP)
- Switches without passive SFP support
Try these steps if you have connection issues:
- Verify that the speed and topology settings on the HBA match those of the switch port. Setting both for automatic negotiation produces the best result.
- Check with the switch vendor to see if the switches work with passive SFP connectors.
- Test with an optical LC-LC optical cable and SFP-LC transceivers.
Note: This issue can also occur using third-party Fibre Channel arrays.
