Input/Output Ports
Ethernet ports
There are five individual Ethernet ports. Ports 2-5 are connected to a switch and can be switched together by
an option in the RouterOS software.
All cables made to EIA/TIA 568A/B cable specifications will work correctly (see Connector Index for pinout).
Note that this port supports automatic cross/straight cable correction (Auto MDI/X), so you can use either
straight or cross-over cable for connecting to other network devices.
LEDs
Ethernet LED lights up when a cable is connected, these LEDs don’t show ethernet activity, just connectivity.
Power LED indicates that the device receives power. ACT LED shows NAND activity and can be programmed to
show other things via RouterOS LED menu.
