Update Menu

General Notes on Updating. Update the only if:

• you need new functions that are not yet supported by your version,
• the new version fixes bugs that affect your system
• your DHD distributor or DHD recommend an update.

Normally, a working system does not have to be updated.

When updating, follow the steps:

1. Connect the core to ethernet
2. Update the kernel, if necessary
3. Update the firmware, if necessary
4. Connect Hardware to the core
5. Load your config

Every device is equipped with the most up-to-date firmware at the time of delivery. Because the software is developed constantly, after a certain time, a newer version might be available than the one in your system. Ask your DHD distributor for the current state of the firmware for your device.

If a newer version is available, you first have to consider whether an update makes sense to you.

If you want to update the firmware, first find out the firmware version on your system.

A firmware update is supplied as a file. Firmware updates of DHD devices are e.g. titled as follows:

XS2-XC2-XD2_08-01-06.fw8 for all 52/XS2, 52/XC2, 52/XD2 cores
XS-XC-XD_08-01-06.fw8 for all 52/XS, 52/XC, 52/XD cores

The shortcut XS-XC-XD_08 or XS2-XC2-XD2_08 describes the firmware version of the device and the type of firmware for different device types. The first and the second number (here: 08 and 01) relate to the major version of the firmware. The third number reflects the minor version of the firmware (here: 06). That means in this example, the file contains firmware version 8.1.6.

When updating the firmware a fourth number is visible. This always must be 01 and indicates that this is an official version. This number is not shown explicitly in the file name. Firmware files have the file extension .fw8 (firmware version 8.x) or .fw9 (firmware version 9.x).

1. In the Update menu select Update Firmware and open the update file. The validity is tested and you are asked to confirm and start the update or cancel the procedure if necessary.

Version number of the devices firmware; Confirmation window before firmware update will be performed.

2. The update starts after you click Yes. The process is indicated by a progress bar and can take some time.

3. After the successful update, you are asked to restart the system. The new firmware is accepted by the system only after this system reboot.

Confirmation message prior to the device reboot.

You can postpone the system reboot, but keep in mind that the system runs on the old firmware version until the reboot is made.

Every device is equipped with the most up-to-date kernel at the time of delivery. Because the software is developed constantly, after a certain time, a newer version might be available than the one in your system. If you have to update your firmware and a newer kernel version is required, your DHD vendor or DHD will tell you to update your kernel.

If you need to update a kernel, first find out the kernel version on your system.

A kernel update is supplied as a file. Kernel updates for a DHD device always have the extension .img.

1. In the Update menu select Update Kernel and open the update file. The validity is tested and you are asked to confirm and start the update or cancel the procedure if necessary.
2. The update starts after you click Yes. The process is indicated by a progress bar and can take some time.
3. After the successful update, you are asked to restart the system. The new kernel is accepted by the system only after this restart.

You can postpone the system reboot, but keep in mind that the system runs on the old kernel version until the reboot is made.
