====== IBM/Lenovo Flex Network installation (BNT) ======

https://flexsystem.lenovofiles.com/help/topic/com.lenovo.acc.en4093.doc/EN4093R_CR_8-2.pdf

====== Network configuration on Lenovo Flex ======

Current Lenovo Flex have network switches BNT EN4093R 

===== Changing between the IBM System Networking OS CLI and isCLI (CISCO like) =====

To change from the IBM System Networking OS CLI to isCLI, enter the following command: 
  boot/mode iscli 
Restart the switch module after this command is run.
  /boot/reset 

To revert from isCLI to the IBM System Networking OS CLI, enter the following command: 
  boot cli-mode IBMNOS-cli 
Restart the switch module after the command is run.

The selected CLI mode is preserved across reboots, even when you restore the switch module to factory defaults. 

Check which mode is inuse (iscli with EXEC mode)

EN4093R loading Software via the Command Line Interface

Follow these steps to load software onto your switch:

  * In Privileged EXEC mode, enter the following command
<cli>
EN4093R# copy {sftp|tftp|ftp} {image1|image2|boot-image}
</cli>
  * Enter the hostname or IP address of the SFTP, FTP or TFTP server
  Address or name of remote host: <name or IP address>
  * Enter the name of the new software file on the server.
<cli>
  Source file name: <filename>
</cli>
The exact form of the name will vary by server. However, the file location is
normally relative to the SFTP, FTP or TFTP directory (for example, tftpboot).
  * If required by the SFTP, FTP or TFTP server, enter the appropriate username and password.
  * The switch will prompt you to confirm your request.
Once confirmed, the software will begin loading into the switch.
  * When loading is complete, use the following commands to enter Global
Configuration mode to select which software image (image1 or image2) you want to run in switch memory for the next reboot:
<cli>
EN4093R# configure terminal
EN4093R(config)# boot image {image1|image2}
</cli>
The system will then verify which image is set to be loaded at the next reset:
<cli>
  Next boot will use switch software image1 instead of image2.
</cli>  
  * Reboot the switch to run the new software:
<cli>
EN4093R(config)# reload
</cli>
The system prompts you to confirm your request. Once confirmed, the switch will
reboot to use the new software

**Note:** If you select “No” when asked to confirm the reload, any changes made to
the configuration since the last reboot will be lost.

===== Recovery =====

The Boot Management Menu
The Boot Management menu allows you to switch the software image, reset the
switch to factory defaults, or to recover from a failed software download.
You can interrupt the boot process and enter the Boot Management menu from the
serial console port. When the system displays Memory Test, press <Shift + B>.
The Boot Management menu appears.
<code>

I - Change booting image
C - Change configuration block
R - Boot in recovery mode (tftp and xmodem download of images to

Q - Reboot
E - Exit
Please choose your menu option:
</code>
  
The Boot Management menu allows you to perform the following actions:
  * To change the booting image, press I and follow the screen prompts.
  * To change the configuration block, press C and follow the screen prompts.
  * To perform a software image recovery, press R and follow the screen prompts.
  * To reboot the switch press Q and follow the screen prompts.
  * To exit the Boot Management menu, press E. The booting process continues.
