Firmware update

Updating firmware via system resources

To update the firmware, use any of the following servers: TFTP, FTP, SCP. Router firmware files obtained from the manufacturer should be allocated on the server.

The router stores two copies of the firmware. To ensure the reliability of the firmware update procedure, only the copy that was not used for the last device startup is available for the update.

When update the firmware, the router configuration is converted according to a new version.

When loading a router with an older software version than the previously loaded configuration, the configuration is not converted and is subsequently deleted.

Firmware from earlier versions can be updated using instructions in the Updating firmware via bootloader section.

To update the firmware for the device running the operating system, follow procedure described below.

Prepare the selected server for operation. The server address must be known; also firmware distributive file should be loaded onto the server.
The router should be prepared for operation according to the documentary requirements. Router configuration should allow for data exchange with the server via TFTP/FTP/SCP and ICMP protocols. Server's belonging to the security zones of the router must be taken into account.
Connect to the router locally via Console port or remotely via Telnet or SSH.
Check the server availability for the router using ping command on the router. If the server is not available, check the router settings and the status of the server network interfaces.
To update the router firmware, enter the following command. Specify IP address of the server being used as <server> For updates that utilize FTP or SCP server, enter a username (<user> parameter) and a password (<password> parameter). Specify the name of the firmware file loaded onto the server as <file_name> parameter (when using SCP, the full path must be as <folder> parameter). When the command is executed, router will copy the file into its internal memory, perform data integrity check and save it into non-volatile memory.
TFTP:
```
esr# copy tftp://<server>:/<file_name> system:firmware
```
CODE
FTP:
```
esr# copy ftp://[<user>[:<password>]@]<server>:/<file_name> system:firmware
```
CODE
SCP:
```
esr# copy scp://[<user>[:<password>]@]<server>://<folder>/<file_name>system:firmware
```
CODE
SFTP:
```
esr# copy sftp://[<user>[:<password>]@]<server>:/<file_name> system:firmware
```
CODE
Example of updating main firmware via SCP:
```
esr# copy scp://adm:password123@192.168.16.168://home/tftp/firmware system:firmware
```
CODE

To start the device with the new firmware version, switch the active image. With show bootvar command, locate the image number, containing updated firmware.

esr# show bootvar
Image   Version                      Date                   Status         After reboot   
-----  --------------               --------------------    ------------   ------------

                                     16:12:54             

2       1.0.7 build 141[f812808]     date 18/02/2015 time   Not Active
                                     16:12:54

CODE

Use the following command to select the image:

esr# boot system image-[1|2]

CODE

To update the secondary bootloader (U-Boot), enter the following command: Specify IP address of the server being used as <server> parameter. For updates that utilize FTP or SCP server, enter a username (<user> parameter) and a password (<password> parameter). Specify the name of the secondary bootloader onto the server as <file_name> parameter (when using SCP, the full path must be as <folder> parameter). When the command is executed, router will copy the file into its internal memory, perform data integrity check and save it into non-volatile memory.
TFTP:
```
esr# copy tftp://<server>:/<file_name> system:boot-2
```
CODE
FTP:
```
esr# copy ftp://<server>:/<file_name> system:boot-2
```
CODE
SCP:
```
esr# copy scp://[<user>[:<password>]@]<server>://<folder>/<file_name>system:boot-2
```
CODE
SFTP:
```
esr# copy sftp://<server>:/<file_name> system:boot-2
```
CODE

Updating firmware via bootloader

Router firmware may be updated via the bootloader as follows:

When U-Boot finishes the router initialization, break the device startup with the <Esc> key.
