The four combo interfaces each have two physical connectors of which the only one can be used at the same time. The ports will be automatically
represented as combo 1-4 in RouterOS. It is possible to select which physical port will be used in the RouterOS software ethernet menu. If left to default
"auto", and both F/T have cables plugged in, SFP will take priority. For example, if you have plugged an Ethernet cable into the 1T port and an SFP
module in the 1F port, you will have to choose in RouterOS which one to use. Double click the respective combo interface in RouterOS GUI to see which
socket is used.
Reset button
The RouterBOOT reset button has the following functions. Press the button and apply the power, then:
Release the button when green LED starts flashing, to reset RouterOS configuration to defaults.
Release the button when the LED turns solid green to clear all configuration and defaults.
Release the button after LED is no longer lit (~20 seconds) to cause a device to look for Netinstall servers (required for reinstalling RouterOS over
the network).
Regardless of the above option used, the system will load the backup RouterBOOT loader if the button is pressed before power is applied to the device.
Useful for RouterBOOT debugging and recovery.
