Resolution

If the FUMS Series Unmanaged Ethernet Switches do not connect with each other, solution is limited.

Verify the FSFP module is the correct mode of fiber, wavelength, through put and that transmission distance for the module is not exceeded. Also Verify that only the 1000Mbps FSFP are used on the FUMS.

 

There is no Optical Link Indicator to verify laser operation; Resolution is

  1. Swap FUMS transceivers to isolate failed units.
  2. Swap FSFP modules to isolate a bad connection.
  3. Replace Device.

NOTE: Only 1000Mbps will work with the FUMS-GFX8 or FUMS-GFX4 units, 100Mbps will not work there will be no link light on both units
