This page is currently under construction. You can edit the article to help completing it. This page covers the MikroTik RouterBoard921-series, which is a stripped down version of the RouterBoard 922. MikroTik uses this board as base for some other products, like mANTBox 15s (https://mikrotik.com/product/RB921GS-5HPacD-15S) mANTBox 19s (https://mikrotik.com/product/RB921GS-5HPacD-19S) NetMetal 5SHP (https://mikrotik.com/product/RB921UAGS-5SHPacD-NM) NetMetal 5SHP triple (https://mikrotik.com/product/RB921UAGS-5SHPacT-NM) The board has QCA9557 @ 720MHz; 128MB RAM; 128MB NAND, 64kB config-NOR; 1G Lan-port; QCA9892 5GHz a/n/ac. The concrete antenna differs on the final model. On the right-side of the pcb is still the printing “RB922GS 5HPac”, which shows the origin of the design. A bit above is the not populated MiniPCI-e socket, on the lower right end is the unpopulated USB-connector.

Flash Layout Find out flash layout, then add the flash layout table here (copy, paste, modify the example). Please check out the article Flash layout. It contains examples and explanations that describe how to document the flash layout. OEM easy installation For full documentation have a look at Common Procedures for Mikrotik RouterBoard Products How you install OpenWrt, using Mikrotik mANTBox 15s as example: You need a DHCP server because the device is using DHCP to get the first IP. You can use dnsmasq (see below) for this task. Start DHCP server and do the following: boot Mikrotik Routerboard. Search the IP of the device in DHCP server log. Log into web interface with user: “admin” and empty password System → Routerboard → Settings → Boot device: Try ethernet once then NAND. This configuration is only valid for the next reboot. This means that you need to activate this again if you your first try to install OpenWRT was not successful. System → Routerboard → Settings → Boot protocol: DHCP System → Routerboard → Settings → Force Backup Booter: Checked (if supported by your routerboard - !IMPORTANT) System → shutdown (NO reboot) Start DHCP server and TFTP server (if not already done): configure fix IP for TFTP server, e.g. 192.168.1.2 download ramfs images. Copy images to e.g. /srv/tftp initramfs: https://downloads.openwrt.org/releases/19.07.4/targets/ar71xx/mikrotik/openwrt-19.07.4-ar71xx-mikrotik-vmlinux-initramfs.elf start dnsmasq with the following command (replace enp0s25 with your network adapter) dnsmasq -i enp0s25 --dhcp-range=192.168.1.100,192.168.1.200 --dhcp-boot=openwrt-19.07.4-ar71xx-mikrotik-vmlinux-initramfs.elf --enable-tftp --tftp-root=/srv/tftp/ -d -u age -p0 -K --log-dhcp --bootp-dynamic start mANTBox if you see in dnsmasq log that vmlinux-initramfs.elf image was send to 192.168.1…. then mANTBox is booting OpenWRT wait for one/two minutes… on the Mikrotik device a non-persistent firmware is installed. You can now access the web interface of OpenWRT. Note: If you do reboot the device now the original Mikrotik firmware is booted! Connect to newly flashed OpenWRT (via web interface or ssh) Install the final persistent firmware now via OpenWRT tools (e.g. upload https://downloads.openwrt.org/releases/19.07.4/targets/ar71xx/mikrotik/openwrt-19.07.4-ar71xx-mikrotik-nand-large-ac-squashfs-sysupgrade.bin ) Device should reboot automatically. Done. Upgrading OpenWrt → generic.sysupgrade These are generic instructions. Update with your router's specifics. LuCI Web Upgrade Process Browse to http://192.168.1.1/cgi-bin/luci/mini/system/upgrade/ LuCI Upgrade URL Upload image file for sysupgrade to LuCI Wait for reboot Terminal Upgrade Process If you don't have a GUI (LuCI) available, you can alternatively upgrade via the command line. There are two command line methods for upgrading: sysupgrade mtd Note: It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing. sysupgrade Login as root via SSH on 192.168.1.1, then enter the following commands: cd /tmp wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc sysupgrade /tmp/xxx.abc mtd If sysupgrade does not support this router, use mtd. Login as root via SSH on 192.168.1.1, then enter the following commands: cd /tmp wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc mtd write /tmp/xxx.abc linux && reboot Debricking → generic.debrick Failsafe mode → failsafe_and_factory_reset Basic configuration → Basic configuration After flashing, proceed with this. Set up your Internet connection, configure wireless, configure USB port, etc. Specific Configuration Please fill in real values for this device, then remove the EXAMPLEs Network interfaces The default network configuration is: Interface Name Description Default configuration br-lan EXAMPLE LAN & WiFi EXAMPLE 192.168.1.1/24 vlan0 (eth0.0) EXAMPLE LAN ports (1 to 4) EXAMPLE None vlan1 (eth0.1) EXAMPLE WAN port EXAMPLE DHCP wl0 EXAMPLE WiFi EXAMPLE Disabled Buttons → hardware.button on howto use and configure the hardware button(s).
