RouterOS includes many configuration options in addition to what is described in this document. We suggest starting here to get yourself accustomed to the possibilities: https://wiki.mikrotik.com/wiki/Manual:CRS3xx_series_switches.
In case the IP connection is not available, the Winbox tool (https://mt.lv/winbox) can be used to connect to the MAC address of the device.
The device is equipped with an RS-232 serial port, set by default to 115200 bit/s, 8 data bits, 1 stop bit, and no parity. For recovery purposes, it is possible to boot the device for reinstallation, see the next section.
Buttons and Jumpers
The reset button has these functions:
- Hold this button during boot time until the user LED light starts flashing, and release the button to reset the RouterOS configuration.
- Keep holding the button for 5 more seconds or until the user LED turns off, then release it to make the RouterBOARD look for Netinstall servers. The first Ethernet port is used for the Netinstall process.
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. Release the button before LED begins to flash, to only load the backup RouterBOOT without resetting. This is useful for RouterBOOT debugging and recovery.
- The power LED is lit when the router is powered from by the DC jack or PoE.
- The user LED can be configured from RouterOS.
- The port LEDs indicate the individual Ethernet and SFP port activity.
The package includes the following accessories that come with the device:
