SWR2311P Firmware V2.02.27

How to update the firmware

For details, please refer to the "Yamaha LAN Monitor User Guide" and the Web GUI help menu.

  1. Connect the SWR2311P-10G and the computer with a LAN cable.
    Please connect to a port of SWR2311P-10G set as VLAN1.
  2. Start the Yamaha LAN Monitor.
  3. Select the SWR2311P-10G to be updated in the tree view.
  4. Click the [Web GUI] button on the device detail view.
    With the factory settings, the username and password are not specified, so entering a username and password would be unnecessary in that case.
  5. Select [Management] -> [Maintenance] -> [Update firmware], then click the [Next] button on "Update firmware from PC."
  6. Click the [Select a file] button, then select the downloaded and decompressed firmware file with extension .bin.
  7. Click the [OK] button.
  8. Click the [Execute] button.

Wait until completing the update. SWR2311P-10G will automatically restart and become ready to use.
