Feature Limitations

Before USB-based deployment

  • Only the switches using SRUH, SRUE or SRUC main control units support USB-based deployment.
  • USB-based deployment is mutually exclusive with the SVF and EasyDeploy functions.
  • Before using a USB flash drive to upgrade a device, ensure that the device can start successfully and has sufficient space to store the required files.
  • Devices to be deployed are unconfigured devices and do not have security measures configured. Therefore, when onsite non-professionals perform deployment task, ensure that they do not perform any unauthorized operations on the devices, USB flash drive, and deployment files.

  • Only one USB flash drive can be connected to a device.
  • The USB flash drive must be connected to the master MPU of a device. If it is connected to the standby MPU, the USB-based deployment process will not start. In a cluster, the USB flash drive must be connected to the system master MPU of the cluster.
  • When using the USB-based deployment function to set up a CSS, you need to insert the USB flash drive into the master MPUs of the two CSS members after the two member switches complete startup. If the USB flash drive has been inserted into the master MPUs before the two switches start, the CSS cannot be set up.
  • In USB-based deployment scenarios, the devices may be upgraded to V200R009C00 or a later version after restart. In this case, the devices check whether the configuration file for next startup contains WLAN configuration that conflicts with the software package for next startup. If so, the devices cannot restart and the USB-based deployment fails. The error report file usbload_error.txt is generated in the root directory of the USB flash drive, which records the failure causes. To solve this problem, you need to use eDesk to convert the configuration file and then set it as the next startup configuration file.

  • The file system format of the USB flash drive must be FAT32, and standard for the USB interface is USB2.0. USB flash drives from different vendors differ in model compatibility and drivers. If a USB flash drive cannot be used, try to replace it with another one from a mainstream vendor. Switches support a maximum of 128 GB USB flash drives.

During USB-based deployment

  • Before saving files to a USB flash drive, disable the write-protection function of the USB flash drive.
  • Do not power off the device during a USB-based deployment process. Otherwise, the upgrade fails or the device cannot start.
  • Do not remove the USB flash drive before the USB-based deployment process is complete. Otherwise, data in the USB flash drive may be corrupted.
  • If upgrade files include a configuration file, you are advised to configure an encryption password for the configuration file, and enable HMAC check to enhance security.
  • In USB-based deployment, the deployment may fail because the device configuration is not restored. In this case, you can remove and then install the USB to resolve this problem.
