RB450Gx4

First use

The RB450Gx4 is an Ethernet router with five Gigabit Ethernet ports, a serial port, two power jacks, and a microSD card slot. It is powered by MikroTik RouterOS. It comes without an enclosure, you are free to use it on your own.

  • Install the board in a case.
  • Connect Ethernet cables and plug in the microSD card (optional).
  • Plug-in power cable or PoE powered ethernet cable in Ether1 to turn on the device.

Powering

The device accepts power in the following ways:

  • direct-input power jacks J1/J2 (5.5mm outside and 2mm inside diameter, female, pin positive plug) both accept 10-57V DC.
  • Ether1 Ethernet port accepts 12-57V DC input (at the board; higher voltage needed to compensate for power loss on long cables) from 802.3af/at or passive Power over Ethernet sources.

Max total power consumption with all interfaces loaded is 5 W. You can use any or all inputs at the same time, they will work in failover mode.

Booting process

RouterOS is the operating system of all RouterBOARD routers. Please see documentation: https://mt.lv/help
This device is not preconfigured other than an IP address on the ethernet port. Another configuration has to be applied according to the documentation manual linked above.
The initial connection has to be done via the ethernet cable, using the MikroTik Winbox utility. Winbox should be used to connect to the default IP address of 192.168.88.1 with the username admin and no password.
In case you wish to boot the device from the network, for example, to use MikroTik Netinstall, hold the reset button of the device when starting it until the LED light turns off, and the device will start to look for Netinstall servers.
In case the IP connection is not available, the Winbox utility can also be used to connect to the MAC address of the device. More information in the documentation.

Extension slots and ports

  • Five Gigabit Ethernet ports (Auto MDI/X). The first Ethernet port accepts 8-30V DC powering from a passive PoE injector or 802.3af/at PoE switch. Use 12V or more to compensate for any losses in cables. The other four Ethernet ports do not support PoE input.
  • The Ether5 port is capable of powering another RouterBOARD device with passive PoE (up to 57 V). The maximum output current is 500 mA.
  • Onboard DB9 RS232C asynchronous serial port is set by default to 115200bit/s, 8 data bits, 1 stop bit, no parity. Note that the device does not fully implement the hardware (RTS/CTS) flow control, so it is suggested to try to disable hardware flow control in the terminal emulation program.
  • microSD card for additional file storage.

Buttons and jumpers

RouterBOOT reset button. This button has the following functions:

  • To use the reset button, hold it and then turn on the device, while still holding the button.
  • Release the button when the green LED starts flashing, to reset RouterOS configuration. To not load backup bootloader, you can start holding the button after power is already applied.
  • Release the button after LED is no longer flashing (~20 seconds) to cause the device to look for Netinstall servers (required for reinstalling RouterOS over the network). You can also release the button at the time when the device has appeared in the Netinstall utility device list.

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.

Operating system support

The device only supports RouterOS software with the version number at or above what is indicated in the RouterOS menu /system resource. Other operating systems have not been tested.
