Updating firmware

New versions of CPE device software are distributed by Kaspersky in the form of firmware. You can download a TAR.GZ archive with the firmware from the the /cpe directory of the distribution kit. You can update the firmware on a CPE device in three ways:

• Manually updating the CPE device firmware without using the orchestrator web interface.
• Scheduling firmware updates on selected CPE devices. In this case, you upload the firmware to the orchestrator web interface, select the CPE devices on which you want to update the firmware, and then update the firmware. A firmware update task is automatically created in the task scheduler.
• Scheduling firmware updates on CPE devices with specific tags. In this case, you upload the firmware to the orchestrator web interface, assign tags to CPE devices on which you want to update the firmware, and then create a firmware update task in the task scheduler. When creating the task, you need to specify the tags you assigned to CPE devices.

The CPE device restarts during the firmware update process.

The table of the firmware uploaded to the web interface is displayed in the SD-WAN→Firmware section. Information about firmware is displayed in the following columns of the table:

• Version is the firmware version.
• Size (MB) is the size of the firmware archive in megabytes.
• SHA256 is the hash of the firmware.
• Architecture is the instruction set architecture (ISA) of the firmware.
• Release date is the firmware release date.
• Model is the model of CPE devices with which the firmware is compatible.

The actions you can perform with the table are described in the Managing solution component tables instructions.
