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.
