Memory and Storage Devices
Memory
There is no onboard memory, but the device has a SODIMM slot for one DDR2 module, it is recommended to
use modules with at least 667MHz (PC-4200). The RB1100 device supports modules of up to 2GB, but due to
software limitations, RouterOS will be able to use only 1.5GB of it.
microSD slot
The board has one microSD card slot which supports microSD and microSDHC cards for expanding the storage
in RouterOS

Input/Output Ports
Ethernet ports
There are thirteen ethernet ports. There are two switch groups, five ports each. The Ether13 port supports
Power over Ethernet.
The RB1100 device also has two Ethernet bypass ports (Ether11 and Ether12). The bypass mode can be
activated by turning the bypass switch next to them to the position 1. Position 0 turns off the bypass mode and
ports work as usual.
All cables made to EIA/TIA 568A/B cable specifications will work correctly (see Connector Index for pinout).
Note that this port supports automatic cross/straight cable correction (Auto MDI/X), so you can use either
straight or cross-over cable for connecting to other network devices.
Ethernet bypass mode
Bypass mode is used to cross-connect the two RJ45 connectors (Ether11 and Ether12) electrically thus creating
an extended Layer 1 network. Traffic present on either network (Internal or External) is seen on the other
network immediately.
If the router would stop working for some reason, the ports would be connected together as if there would be
no router in between. You could configure your network to allow this, and in case of hardware failure, the
communications would still work, as if the (broken) router wouldn't exist there.
DB9 Serial Port
The RS232C standard male DB9 asynchronous serial port may be used for initial configuration, or for attaching
a modem or any other RS232 serial device. TxD (pin 3) of this port has -5V DC power when idle. Some signals
are not connected, so this implementation may not be considered to support full hardware flow-control, so
software flow-control (XON/XOFF) or none at all should be used.
Fan Connectors
You can connect up to four fans to the RouterBOARD, but only two of them will work at a time. They will
receive 12V DC power. The board supports fan speed feedback signaling. RouterOS can be configured to
change the active fan, if the current active one is not rotating (note that if a fan does not have rotation sensor,
it will be considered failed).
LEDs
Power LED
Power LED is on when the board is powered.
User LED
User LED may be programmed at user's option. It is lit by default when the board starts up, then it is turned off
when the bootloader runs kernel.
User's Guide
Assembling the Hardware
In most cases you do not need to use any additional boot devices, as you can boot the RouterBOARD from the
onboard NAND memory. You can also install one microSD card which you can use as an alternative boot device
(not for RouterOS) or additional storage media;

6
To disassemble the case, you will need a Phillips P2 screwdriver.
Powering
Power options:
1. PoE on Ether13 supports 12-24V DC powering with a passive PoE injector. The device does not support
power over datalines.
2. J11 power connector, used when device installed in a rackmount case, 12-24V DC. Connects to the
built-in PSU.
Booting options
First, RouterBOOT loader is started. It displays some useful information on the onboard RS232C asynchronous
serial port, which is set to 115200bit/s, 8 data bits, 1 stop bit, no parity by default. Also supports hardware
(RTS/CTS) flow control. The loader may be configured to boot the system from the onboard NAND module or
from Ethernet network. See the respective section of this manual for how to configure booting sequence and
other boot loader parameters.
Onboard NAND Storage Device
The RouterBOARD may be started from the onboard NAND storage chip. As there is no partition table on the
device, the boot loader assumes the first 4MiB form a YAFFS filesystem, and executes the file called “kernel”
stored in the root directory on that partition. It is possible to partition the rest of the medium by patching the
kernel source.
Internal Storage Device
The RouterBOARD may be started from a microSD card slot, although RouterOS doesn't support this. At least
two partitions must exist on the device, first of which being the ELF image the board is to be booted from
(normally, it is a Linux kernel, appended with the kernparm ELF section that specifies the root partition name
and, optionally, other kernel parameters of your choice).
Booting from network
Network boot works similarly to PXE or EtherBoot protocol, and allows you to boot a RouterBOARD 1100
series boards from an executable image stored on a TFTP server. It uses BOOTP or DHCP (configurable in boot
loader) protocol to get a valid IP address, and TFTP protocol to download an executable (ELF) kernel image
combined with the initial RAM disk (inserted as an ELF section) to boot from (the TFTP server's IP address and
the image name must be sent by the BOOTP/DHCP server).
To boot the RouterBOARD computer from Ethernet network you need the following:
An ELF kernel image for the loader to boot from (you can embed the kernel parameters and initrd image
as ELF sections called kernparm and initrd respectively)
A TFTP server which to download the image from
A BOOTP/DHCP server (may be installed on the same machine as the TFTP server) to give an IP address,
TFTP server address and boot image name
See the RouterBOOT section on how to configure loader to boot from network.
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).

Operating System Support
MikroTik RouterOS, starting from version v5, is fully compatible with RouterBOARD 1100 series embedded
boards. If your device is preinstalled with an earlier RouterOS release, please upgrade RouterOS to v4.9 or
newer.
RouterBOOT
The RouterBOOT firmware (also referred as Bootloader here) provides minimal functionality to boot an
Operating System. It supports serial console via the onboard serial port at the boot time. The loader supports
booting from the onboard NAND device and from a network server (see the respective section for details on
this protocol).
Boot Loader Configuration
Loader parameters may be configured through the onboard RS232C DB9 asynchronous serial interface. To
connect to it, use a standard null-modem cable. By default, the port is set to 115200bit/s, 8 data bits, 1 stop
bit, no parity. Note that the device also implements the hardware (RTS/CTS) flow control.
To enter the loader configuration screen, press any key (or only [Delete] key (or [Backspace] key –see the note
for the respective configurable option), depending on the actual configuration) just after the boot loader is
asking for it:
RouterBOOT booter 2.27
RouterBoard 1100
CPU frequency: 800 MHz Memory size: 512 MB
Press any key within 2 seconds to enter setup

p - boot protocol
t - do memory testing
x - exit setup
your choice:
To select a menu point, press the key written at the beginning of this line. Pressing [Enter] selects the option
marked with '*'.
boot delay –how much time to wait for a key stroke while booting (1..9 seconds; 2 second by default).
boot key –which key will cause the loader to enter configuration mode during boot delay (any key | <Delete>
key only; any key by default). Note that in some serial terminal programs, it is impossible to use the [Delete]
key to enter the setup –in this case it might be possible to do this with the [Backspace] key.
serial console –to configure initial serial console bitrate (1200 | 2400 | 4800 | 9600 | 19200 | 38400 | 57600
| 115200; 115200 bps by default).

boot device –initial boot device (boot over Ethernet | boot from NAND, if fail then Ethernet | boot from
CompactFlash only | boot Ethernet once, then NAND | boot Ethernet first, then CompactFlash | boot from
NAND only; boot from NAND, if fail then Ethernet by default). You can also select boot chosen device option
to boot from the device selected immediately, without saving the setting.
reset configuration –whether to reset all the boot loader settings to their respective default values (yes | no;
no by default).
format nand –perform a low-level NAND format. During this operation, all previously marked bad sectors are
retested to find out if they are faulty indeed.
upgrade firmware –receive a new boot loader image using XModem protocol over serial line or using
DHCP/BOOTP and TFTP protocols through the Ethernet network (upgrade firmware over ethernet | upgrade
firmware over serial port).
board info –prints the serial number, boot loader version, CPU frequency, memory size and MAC addresses of
the onboard Ethernet ports
boot protocol –network booting protocol (bootp protocol | dhcp protocol; bootp protocol by default).
do memory testing –performs a full memory test.

Boot Loader Upgrading
The boot loader is needed to initialize all the hardware and boot the system up. Newer loader versions might
have support for more hardware, so it's generally a good idea to upgrade the loader once a newer version is
available.
The boot loader upgrading is possible from MikroTik RouterOS, from within the “/system routerboard” menu.
Updates are included with each RouterOS update. The procedure is described in the MikroTik RouterOS
manual: http://wiki.mikrotik.com/wiki/Manual:Bootloader_upgrade
You can also upgrade the loader through the onboard serial port using XModem protocol (programs available
for all major OSs). For example, you can use HyperTerminal for Windows or Minicom for Linux to upload the
boot loader. Alternatively if you have a DHCP/BOOTP and TFTP servers available, you can specify the loader
image as a boot image and choose the bios upgrade over ethernet option in the boot loader configuration
menu. The loader will get the image from the TFTP server and upgrade itself. The most current loader image is
available for download on www.routerboard.com.

Primary Boot Loader
There are two boot loaders present on the NOR flash memory chip. Secondary is the main one, that is
executed by default. This is the one that can be upgraded. In case something goes wrong in the upgrade
process, or you have set some incorrect settings that render it unusable, you can load the Primary boot loader
by holding the Software Reset 1 button (S1), connecting the power, and then releasing the button/jumper. The
Primary boot loader has the default settings, which can not be changed. It is also not possible to upgrade it.

The Software Reset 2 button (TP12) reset hole, which resets both boot loader settings and RouterOS setting by
default, can be disabled in this menu (it will still reset the boot loader settings).
Software Reset
It is possible to reset all software configuration by using the Software Reset 2 button hole (C229, see
schematic) during the power-up. No confirmation or passwords will be asked, so use with caution. This feature
can be disabled in the “system routerboard settings” menu by switching the “enable-jumper-reset”
parameter to “no”. Simply use a metal object to short circuit the metallic reset hole (TP12) while booting.
