A seguito presso intervento di un grosso cliente ci siamo imbattuti nel reboot continuo di alcune RB433, ripristinando il software le RB sono ritornate operative, a seguire gli step
NetInstall is a program that runs on Windows computer that allows you to install MikroTiK RouterOS onto a PC or onto a RouterBoard via an Ethernet network.
You can download Netinstall on our download page.
NetInstall is also used to re-install RouterOS in cases where the the previous install failed, became damaged or access passwords were lost.
- Your device must support booting from ethernet, and there must be a direct ethernet link from the Netinstall computer to the target device. All RouterBOARDs support PXE network booting, it must be either enabled inside RouterOS "routerboard" menu if RouterOS is operable, or in the bootloader settings. For this you will need a serial cable.
Note: For RouterBOARD devices with no serial port, and no RouterOS access, the reset button can also start PXE booting mode. See your RouterBOARD manual PDF for details. For example RB750 PDF
- Netinstall can also directly install RouterOS on a disk (USB/CF/IDE/SATA) that is connected to the Netinstall Windows machine. After installation just move the disk to the Router machine and boot from it.
The following options are available in the Netinstall window:
- Routers/Drives - list of PC drives, and in the routers that were detected near the Netinstall PC
- Make floppy - used to create a bootable 1.44" floppy disk for PCs which don't have Etherboot support
- Net booting - used to enable PXE booting over network (your default choice)
- Install/Cancel - after selecting the router and selecting the RouterOS packages below, use this to start install
- SoftID - the SoftID that was generated on the router. Use this to purchase your key
- Key / Browse - apply the purchased key here, or leave blank to install a 24h trial
- Get key - get the key from your mikrotik.com account directly
- Flashfig - launch Flashfig - the mass config utility which works on brand new devices
- Keep old configuration - keeps the configuration that was on the router, just reinstalls software (no reset)
- IP address / "Netmask - enter IP address and netmask in CIDR notation to preconfigure in the router
- Gateway - default gateway to preconfigure in the router
- Baud rate - default serial port baud-rate to preconfigure in the router
- Configure script File that contains RouterOS CLI commands that directly configure router (e.g. commands produced by export command). Used to apply default configuration
- for installation over network, don't forget to enable the PXE server, and make sure Netinstall is not blocked by your firewall or antivirus. The connection should be directly from your Windows PC to the Router PC (or RouterBOARD), or at least through a switch/hub.
This is a step by step example of how to install RouterOS on a RouterBoard 532 from a typical notebook computer.
The Notebook computer must be equiped with the following ports and contain the following files:
- Ethernet port.
- Serial port.
- Serial communications program (such as Hyper Terminal)
- The .npk RouterOS file(s) (not .zip file) of the RouterOS version that you wish to install onto the Routerboard.
- The NetInstall program available from the Downloads page at www.mikrotik.com
- Connect the routerboard to a switch, a hub or directly to the Notebook computer via Ethernet. The notebook computer Ethernet port will need to be configured with a usable IP address and subnet. For example: 10.1.1.10/24
- Connect the routerboard to the notebook computer via serial, and establish a serial communication session with the RouterBoard. Serial configuration example in in the Serial console manual
- Run the NetInstall program on your notebook computer.
- Press the NetInstall "Net Booting" button, enable the Boot Server, and enter a valid, usable IP address (within the same subnet of the IP address of the Notebook) that the NetInstall program will assign to the RouterBoard to enable communication with the Notebook computer. For example: 10.1.1.5/24
- Set the RouterBoard BIOS to boot from the Ethernet interface.
Configuring RouterBOARD without COM port
- To boot RouterBOARD withtout COM port from Network, you can use reset button. Consult RouterBOARD.com and specific RouterBOARD User Guide to find reset button location and usage instructions. For example RB751U-2HnD etherboot instructions,
RouterBOARD 751U-2HnD RouterBOOT reset button (RES, front panel) has two functions to reset RouterOS configuration and boot it from Etherboot: - Connect Netinstall PC to "ether1" port and hold this button during boot time longer, until LED turns off, then release it to make the RouterBOARD look for Netinstall servers.
- As well Etherboot can be configured by RouterOS (when you have access to it),
system routerboard settings set boot-device=try-ethernet-once-then-nand
Configuring RouterBOARD with COM port
To access Routerboard BIOS configuration: reboot the Routerboard while observing the activity on the Serial Console. You will see the following prompt on the Serial Console “Press any key within 2 seconds to enter setup” indicating that you have a 1 or 2 second window of time when pressing any key will give you access to Routerboard BIOS configuration options.
(press any key when prompted):
You will see the following list of available BIOS Configuration commands. To set up the boot device, press the 'o' key:
What do you want to configure? d - boot delay k - boot key s - serial console l - debug level o - boot device b - beep on boot v - vga to serial t - ata translation p - memory settings m - memory test u - cpu mode f - pci back-off r - reset configuration g - bios upgrade through serial port c - bios license information x - exit setup
Next Selection: Press the 'e' key to make the RouterBoard to boot from Ethernet interface:
Select boot device: * i - IDE e - Etherboot 1 - Etherboot (timeout 15s), IDE 2 - Etherboot (timeout 1m), IDE 3 - Etherboot (timeout 5m), IDE 4 - Etherboot (timeout 30m), IDE 5 - IDE, try Etherboot first on next boot (15s) 6 - IDE, try Etherboot first on next boot (1m) 7 - IDE, try Etherboot first on next boot (5m) 8 - IDE, try Etherboot first on next boot (30m)
The RouterBoard BIOS will return to the first menu. Press the 'x' key to exit from BIOS. The router will reboot.
- Make sure boot-protocol is bootp.
Watch the serial console as the RouterBoard reboots, it will indicate that the RouterBoard is attempting to boot to the NetInstall program. The NetInstall program will give the RouterBoard the IP address you entered at Step 4 (above), and the RouterBoard will be ready for software installation. Now you should see the MAC Address of the RouterBoard appear in the Routers/Drives list of the NetInstall program.
Click on the desired Router/Drive entry and you will be able to configure various installation parameters associated with that Router/Drive entry.
For most Re-Installations of RouterOS on RouterBoards you will only need to set the following parameter:
Press the "Browse" button on the NetInstall program screen. Browse to the folder containing the .npk RouterOS file(s) of the RouterOS version that you wish to install onto the Routerboard.
When you have finalized the installation parameters, press the "Install" button to install RouterOS.
When the installation process has finished, press 'Enter' on the console or 'Reboot' button in the NetInstall program.
1. Reset the BIOS Configuration of the RouterBoard to boot from its own memory.
2. Reboot the RouterBoard.
Reset RouterOS Password
Netinstall can be used to reset password of RouterOS by erasing all configuration from the router. Uncheck 'Keep Old Configuration' during Netinstall and proceed with standard procedure,
