A Gigabit Ethernet Combo port is an Ethernet port and a Mini-GBIC port (also called SFP´s) that share the same switch fabric and port number. A Combo port is a way to provide different types of connectivity without taking up unused switch fabric. These Combo ports can also be labeled as tied, meaning two different physical ports that can only be used one at a time. A Gigabit Ethernet Combo port consists of one 1000Base-T Gigabit over Copper port (provided), and one Mini-GBIC port (empty port that requires Mini-GBIC module).

D-Link DGS Serise Switch, Many models have Gigabit Ethernet Combo port,For More Please visit www.dlink.cc

Note: If a Mini-GBIC port is being used, then the corresponding 1000BASE-T copper port is automatically disabled and vice versa.

Step 1: Connect COM port of the computer to the console port of the switch with a RS-232 serial cable.

Step 2: Open hyperterminal on the computer and configure as followed:

  • Bits per second: 9600
  • Data bits: 8
  • Parity: None
  • Stop bits: 1
  • Flow Control: None

Launch the hyperterminal monitor and Power cycle the switch.
When it boots up, log in using the default user name, admin, and no password.
Press Enter to get the console# prompt.

Step 3: Set an IP address on the switch.
Note: The IP address needs to be on the same subnet as your computer.

Step 4: Open a web browser, such as Internet Explorer or Netscape, and enter the IP address, that you set in the previous step, in the address bar.

eg. .

Step 5: You will be prompted for a user name and password.The default user name is admin and there is no password. Select OK.

Step 6: Select Basic Setup, from the top. Under Vlan, on the left side, select Properties.

You should now see both your Vlans
ie. 1 and 2.


Step 9: Under Vlan.
Select Membership. You should see Vlan 1 the default port settings.


Step 10: Select the ports you wish to assign to Vlan 2.
In this example we use ports 3, 4 and 5 for our Vlan 2.

Step 11: In the example port 5 is being configured for Vlan 2 Selecting Vlan ID 2 and Selecting the number 5 just above port 5.

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:// 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:// 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.

    Some people ask me how to find the D-Link switch serial number, is actually very simple.

    On the bottom of each D-Link Switch/Hub, a sticker has been placed which contains the serial number information for that product.

    An example of the sticker is shown below:


    The circled series of numbers is the Serial number.
