Optical modules are generally used in switches, NICs, routers, and other communication devices, and the related system software of these devices is constantly iterating to fix known problems or expand application functions. Users can choose the switch system software version provided by the host manufacturer according to their own needs when using the switch. Different software versions may have different requirements on the compatibility of optical modules, and by switching the switch system software version, some module compatibility problems can be found or solved in order to improve the module's adaptability in the host.
Below is the method of upgrading the system software of Aruba switch using USB according to specific cases:
      I. A information / material preparation
      1. U.S.D(Usb2.0,file system format is FAT32);
      2. Switch system software (recommended to download from the official website:
www.hpe.com/support/downloads );
      3. network cable;
      4.  switch (Aruba 8320 JL479A), computer;
      II Precautions
      1. To avoid damaging the device, do not interrupt the power supply of the switch during the software update.
      2. Before updating the software, make sure that the downloaded software version supports the switch model that needs to be upgraded, and the software download page usually has information about the system software description.
      III. Upgrade Steps
      1. Set USB as available status
 •  Store the switch system software in a USB flash disk.
 •   Insert the USB flash disk into the USB port of the switch.
 •   Determine the name of the software file stored on the USB flash drive.
 •   Enable USB on the switch with the following command reference.
      
switch>enable  //enter privileged mode
     
 switch#config t  //Enter global configuration
      s
witch(config)#usb  //enter USB
   
  switch(config)#do usb mount  //enable USB
      
switch(config)#do show usb  //check USB status
   
  Enabled : Yes
      Mounted : Yes

      2. Copy the system software file to the switch (the system software version file takes ArubaOS-CX_8320_10.05.0011.swi as an example)
switch#copy usb:/ArubaOS-CX_8320_10.05.0011.swi secondary   //copy the system software from USB to the switch
Explanation: Aruba switch allows to save 2 system software, i.e. there are two locations to choose from: primary and secondary (primary and secondary), users can just choose to start the system software according to the saving location;
      3. Check the uploading of system software files
switch#show image //check the system software file information in the switch to confirm the success of this system software transmission
Note: The previous step will store the system software in secondary, here you can check and confirm in Secondary Image.

Check the system software stored in the switch

      4. Switch the default boot system software version of the switch
switch#boot system Secondary   //Select the default boot version according to the location of system files in the switch: primary/secondary/serviceos, corresponding to step 2
      5. Reboot the switch to verify the current settings

switch#reboot   //Use the command to reboot the switch
      6. After reboot, check the current system software version of the switch

switch#show system   //View the system software running on the switch
