RouterBOARD 450G

Quick Setup Guide and Warranty Information

Assembling the Hardware

First use of the board:

●

Install the board in a case;

●

Connect other peripherals and cables;

●

Plug in power cable, or PoE powered ethernet cable to turn on the device.

Powering

The device accepts powering from either of the two power jacks, or from the LAN1 Ethernet port:

●

direct-input power jacks J7/J8 (5.5mm outside and 2mm inside diameter, female, pin positive plug) accept 9..28 V

DC (overvoltage protection starts at 30V).

●

LAN1 Ethernet port J6 accepts 9..28 V DC input (at the board; higher voltage needed to compensate for power loss

on long cables; at least 18V suggested) from non-standard (passive) Power over Ethernet injectors (no power over

datalines). The board does not work with IEEE802.3af compliant 48V power injectors.

CAUTION: all three power inputs are always active, but only one of them may be used at time to avoid damage of

equipment.

Booting process

First, RouterBOOT loader is started. It displays some useful information on the onboard RS232C asynchronous serial port.

The 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 in case the serial console does not work as expected, and if it does not help, make a new cable using the

pinout given in the User's manual). By default, RouterOS operating system is installed on RouterBOARDs. It is loaded at this

point. The loader may be configured to boot the system from the onboard NAND, and/or from network. See the respective

section of User's manual on how to configure booting sequence and other BIOS parameters.

DHCP or BOOTP (configurable in loader) protocols allow the RB450 device to get an initial IP address, and provide the

address of a TFTP server to download an ELF boot image from. It is especially useful for software installation. See the User's

manual for more information and protocol details. Note that you must connect the RouterBOARD you want to boot and the

BOOTP/DHCP and TFTP servers to the same broadcast domain (i.e., there must not be any routers between them – they

must be on the same Ethernet switch).
