How to upgrade the PROM code on an D-Link xStack series (DGS-3324SR, DGS-3324SRi, DXS-3326GSR, DXS-3350SR) switches?

Step 1: Run HyperTerminal from Start > Programs > Accessories > Communications > HyperTerminal.

Step 2: On the Connection Description window, enter a name for this connection. Click OK.

Step 3: On the Connect To window, select the COM port that the serial cable is connected to using the drop-down box next to Connect Using. Click OK.

Step 4: On the COMX Properties (X represents the COM port number) window, select the following settings using the drop-down boxes:

* Bits per second – 115200
* Data bits – 8
* Parity – None
* Stop bits – 1
* Flow control – Hardware

Click OK.

You will now see a blank screen which shows Connected at the bottom left hand corner of the screen.

Step 5 Log into the switch and then reboot the switch.

Step 6 Press “#” (Shift + 3) before the POST runs to 100%.

Step 7 After a short delay, the switch will attempt to establish a connection to the Z-Modem, as shown below.

Step 8: Click Transfer -> Send File, which will open the “Send File” window:

Step 9: Choose the PROM file to be upgraded by utilizing the Browse button and pressing “Send.” After the file transfer has completed, the device will reboot automatically.
IMPORTANT: During the reboot process, DO NOT power off the switch. Doing so will cause a boot failure and the device cannot be rebooted. The RMA (Return Material Authorization) process will be needed for recovery.

Step 10: After rebooting, the PROM version will be changed.

To upgrade the firmware on the gateway download the latest firmware from the downloads page and follow the directions below.

The firmware for the D-Link DI-704, DI-704P, DI-707, DI-713, and DI-713P:

Please Note: If all of the features of your gateway are operational, do not upgrade the firmware. It will not make your gateway run better and may even disable some features that you are currently using. If it´s not broken, don´t fix it.

Step 1 Download the D-Link DI-704 firmware to your computer.

Step 2 Double-click on this self-extracting file. A window will open allowing you to select a destination folder for the file. It really doesn´t matter where this folder is as long as you can find the file after you click the Unzip button.

Select a destination and click on the Unzip button.

Step 3 Navigate to the destination folder and double-click on the firmware file which will look like the image below.

Step 4 This will open the following window. Enter your password and click OK . This will be the same password that you use to enter the web configuration.

Step 5 You will be prompted to confirm that you want to continue with the upgrade if there are other computers connected to the gateway. Click OK to continue with the upgrade.

Step 6: You will then see a progress bar.

Once it has reached 100% you will be notified that the upgrade was successful. Click OK to close this window. Your gateway´s firmware has now been upgraded.

Step 7: Recycle the power on the gateway by shutting it off for 20 to 30 seconds and then turning it back on again. After upgrading the firmware, it may be necessary to reconfigure your settings. Please check your configuration settings before trying to connect to the Internet.

Note: Before you begin this upgrade you will need a computer running a TFTP server.

If the new firmware version requires a different bootcode, continue to Step 1. If you do not need to upgrade the bootcode continue to Step 4. Step 1: Enter the command copy tftp://(ip address)/(filename) boot.
Where you replace (ip address) with the IP address of the TFTP server and (file name) with the version of boot code you wish to upload.

For example: tftp://192.168.5.300/10025.rfb boot.

Step 2: After the upload is complete, type reload in the command prompt and hit Enter.

Step 3: Once the switch has reloaded, log into the switch and run the command show version. Ensure that the new boot code version was uploaded properly.

You can now upload the new firmware.

Step 4: Enter the command Copy tftp://(ip address)/(file name) image
Where you replace (ip address) with the IP address of the TFTP server and (file name) with the version of firmware you wish to upload.

For example: tftp://192.168.5.300/1109.ros image.

Step 5: After the upload is complete, check the image on the switch by using the following command:
Show bootver and see which image is not active.

Step 6: Run the following command:
Boot system image-<non active image>
Where <non active image> is the non active image (either 1 or 2).

Note: If you are downgrading the firmware to an older version, type delete startup-config, in the command prompt, and hit Enter. Then type y twice in response to the prompts, to proceed.
If it is a newer version, continue to Step 7.

Step 7: After the upload is complete, type reload, in the command prompt, and hit Enter.

Step 8: Once the D-Link switch has reloaded, log into the switch and run the command show version. Ensure that the boot code version and the firmware version is correct.
