# HW guide for unused Ethernet Ports

## Question

Asked by KimTommy on 2014-06-27 in Wireless.

Hi

If we’re only using two Ethernet ports on the WizFi630 do we still need the termination network/input circuit around the unused Ethernet Port (see picture)? Could the unused Ethernet pins be left unconnected from the module to our board?

For Unused Ethernet port, It need not the termmination.
and It can be left unconnected from the module.
