MikroTik RouterBOARD 800 Quick Setup Manual And Warranty Information

RouterBOARD 800
Quick Setup Guide and Warranty Information

Assembling the Hardware

First use of the device:
• Insert the MiniPCI cards. RouterBOARD 800 provides
four MiniPCI slots and one miniPCI-e slot. SIM slot is
not provided, so this slot can't be used with 3G cards.
• (Optional) attach a daughterboard for additional
Interfaces
• Connect antenna cables to the MiniPCI cards.
• Install the device in a case
•
Plug in power cable to turn on the board
• If installing this device in an outdoor location, ensure
proper grounding is installed as well.

Powering

The board accepts powering from either the power jack or
the LAN1 Ethernet port:
●
direct-input power jack J14 (5.5mm outside and 2mm
inside diameter, female, pin positive plug) accepts
10..56 V DC.
●
LAN1 Ethernet port J12 accepts 38..56 V DC input (at
the RouterBOARD. Higher voltage needed to
compensate for power loss on long cables; 48V
suggested) from Power over Ethernet injectors. RB800
supports 802.3af PoE standard powering.
The maximum output of the power supply to the
extensión cards is normally at about 25W (7.5A at 3.3V),
however with appropriate cooling, the onboard power
supply is capable to provide higher power output to the
extension cards. Without load and extension cards, RB800
consumes ~8.2W.

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 MikroTik Online Wiki. 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 RouterBOARD 800 series board 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. 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).
