Hot Swapping


One-Click System Reset
If you press the FUNC button when no SD card or USB flash disk is inserted, the system resets and restarts in the
original software version.

One-Click Software Upgrade
If you press the FUNC button when an SD card or USB flash disk is inserted, the system scans installation packages
that are applicable to the current device in the root directory of the SD card or USB flash disk in sequence. The system
is upgraded immediately after the first available installation package is found. After the upgrade is complete, the system
resets and restarts in the new software version.
The system scans SD cards in prior to USB flash disks. The system scans USB flash disks only when no SD card
is inserted or no installation package is available on the SD cards. If no installation package is available on the
inserted SD card and USB flash disk, the system resets and but does not upgrade the software. The system still
restarts in the original software version.
The installation package file name is in the format of PProduct nameV1_Version number_RRelease
number_install.bin.
The system scans installation packages only in the root directories of the SD card or USB flash disk and the SD
card always has the priority.
It is recommended to save only one installation package in the root directory of the SD card or USB flash disk. If
there are multiple installation packages in the root directory, the system selects an installation package at random.
Therefore, the searching sequence of software versions cannot be ensured.
Procedure
Save the bin file of the installation package for the new software version in the root directory of the SD card or USB
flash disk and insert the SD card or USB flash disk into the device.
The installation package file name is in the format of Product name_Version number_RRelease number_install.bin.
For example, RSR30-X_10.4(3b76)_R199863_install.bin.
Press the FUNC button. The system performs software upgrade and resets.
After system restart, run the show version command to check whether the software version has been updated.
