Guidelines For Upgrading Aruba 8320 Switch System Software Version Using USB

Time: 2022-05-24
        Optical modules are widely deployed in switches, network interface cards (NICs), routers and other communication devices. Device system software is regularly updated to fix known bugs and expand functional features. Users may select manufacturer‑provided switch firmware versions according to practical requirements. Different firmware versions have varied optical‑module compatibility requirements. Upgrading switch firmware helps identify and resolve optical module compatibility issues, improving adaptability between optical modules and the switch.
        Below is a practical step‑by‑step guide for upgrading Aruba 8320 switch firmware using a USB flash drive.
I. Information & Material Preparation
        • USB flash drive (USB 2.0, formatted as FAT32 file system)
        • Switch system software (official download link recommended: www.hpe.com/support/downloads)
        • Network cable
        • Aruba 8320 (JL479A) switch and a computer
II. Precautions
        • Do not cut off power to the switch during the upgrade process to avoid hardware damage.
        • Before upgrading, verify that the downloaded firmware version supports the Aruba 8320 model. Software compatibility details are available on the official download page.
III. Upgrade Steps
1. Prepare and Enable the USB Flash Drive
        • Save the switch firmware file to the USB flash drive.
        • Insert the USB drive into the switch’s USB port.
        • Record the exact firmware filename stored on the USB drive.
        • Enable the USB function on the switch with the following commands (each command on a separate line):
            switch> enable    // Enter privileged mode
            switch# config t    // Enter global configuration mode
            switch(config)# usb    // Enter USB configuration mode
            switch(config)# do usb mount    // Enable and mount the USB drive
            switch(config)# do show usb    // Check USB drive status
        Successful USB availability status output:
            Enabled : Yes
            Mounted : Yes
2. Copy Firmware to the Switch
        Take the firmware file ArubaOS‑CX_8320_10.05.0011.swi as an example. Run the following command to copy the firmware from the USB drive to the switch:
            switch# copy usb:/ArubaOS-CX_8320_10.05.0011.swi secondary
        Note: Aruba switches support two firmware storage partitions: primary (main) and secondary (backup). Users can select the boot partition based on firmware storage location.
3. Verify Firmware Upload
        Run the following command to check stored firmware files and confirm successful file transfer:
            switch# show image
4. Set Default Boot Firmware Version
        Set the default boot partition (consistent with the partition selected in Step 2):
            switch# boot system secondary
5. Reboot the Switch
        Reboot the switch to apply the firmware upgrade:
            switch# reboot
6. Confirm Upgraded Firmware Version
        After the switch restarts, run the following command to check the running firmware version:
            switch# show system
