Fiber can be run long distances to the switch.
These cables require gigabit interface converters (GBICs), SFP+ form factor.
Remember: ThoughtSpot does not supply cables. Your Dell appliance may come with one appliance-side SFP+ per node, but not the switch-side SFP+'s.
The GBIC must be plugged into a data port on the back of the appliance before plugging in the fiber cables.
The fiber cables must then be plugged into the GBIC.
Copper can only be run short distances to the switch. An SFP+ is attached to the cable.
Here is how you would plug in a DAC cable.
