• Choose your powering solution, please see the Powering section for possibilities.
• The Initial connection has to be done via the Ethernet cable, using the MikroTik Winbox utility.
• Use Winbox to connect to the default IP address of 192.168.88.1 from any port, with the username admin and no password, the device is set up as a switch.

• Update the device by clicking the "Check for updates" button to v6.46 or the latest RouterOS software to ensure the best performance and stability. The device needs to have an active internet connection.
• To manually update the device, go to our download page https://mikrotik.com/download
• Choose your architecture (ARM) and download the latest packages from any channel to your PC.
• Open Winbox and upload packages in the Files menu.
• Reboot the device.
• Updating software will ensure the latest security fixes and regulations set by local law.
• Choose your Country.
• Set up your password to secure the device.

Mounting

Image Removed The device is designed to use indoors and it can be mounted in a rackmount enclosure using provided rack mounts, or it can be placed on the desktop. Please attach rubber pegs on the bottom of the router if the desired placement is on the flat surface or use a Phillips screwdriver to attach rackmount ears on both sides of the device if designated use is for rackmount enclosure.

1. Attach rack ears to both sides of the device and tighten four screws to secure them in place, as shown on the picture to the right.
2. Place the device in a rackmount enclosure and align with the holes so that the device fits conveniently.
3. Tighten screws to secure it in place.

The IP rating scale for this device is IPX0. The device has no protection from water contamination, please ensure the placement of the device in a dry and ventilated environment.
We recommend shielded Cat5/6 cables for our devices.
Mounting and configuration of this device should be done by a qualified person.

Powering

The device accepts 11-57 V DC ⎓ from the direct-input power jack (5.5 mm outside and 2 mm inside, female, pin positive plug) accepts. The Ethernet port 1 accepts 802.3af/at and passive PoE power input (18-57 V DC).
The power consumption of this device under maximum load is up to 17 W. It is possible to connect both power inputs at the same time and they will work in fail-over mode (input with higher voltage will work as the main source).
When using 802.3af/at to power this device, we recommend not using grounding for best compatibility.

Configuration

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, no parity. For recovery purposes, it is possible to boot the device for reinstallation, see the next section.
The device supports booting RouterOS (for routing and switching configuration) or SwOS (for only using as a switch). By default, the device will boot RouterOS, but you can reboot into the other operating system in the following ways:

• From SwOS: In the System menu, click the "Boot RouterOS" button on the bottom of the page.
• From RouterOS: in the System, RouterBOARD menu, click "Settings" and there select "Boot OS".

It is also possible to select the OS and configure other boot settings via the serial console menu.

Buttons and Jumpers

The reset button has these functions:

• Hold this button during boot time until the user LED light starts flashing, release the button to reset 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 backup RouterBOOT without reset. This is useful for RouterBOOT debugging and recovery.

LED indicators

• The power LED is lit when the router is powered from the DC jack or PoE.
• The user LED can be configured from RouterOS.
• The port LEDs indicate the individual Ethernet and SFP port activity.
