In order for the Unified Switch to be able to discover and manage access points, the WLAN switch and its operational status must both be enabled. The WLAN component is enabled by default.

When you access the switch user interface, make sure you set the correct country code for the switch so that the access points can only operate in the modes permitted in your country. The default country code is US for operation in the United States.

NOTE:Wireless features are available under the WLAN tab on the navigation menu.

NOTE:Most configuration pages have a Submit button, which applies the changes to the running configuration but does not save them to non-volatile memory (NVRAM). To make the changes permanent so they persist across a reboot,click the Tool, then click Save Changes to navigate to the appropriate page.You can also use the write command in Privileged Exec mode.

How to Enabling the WLAN Features on the D-Link Wireless Switch DWS-3026

Basic Wireless Global Configuration

1.Enable WLAN Switch

Check the box to enable WLAN switching functionality on the system. Clear the check box to administratively disable the WLAN switch.

If you clear the check box, all peer switches and APs that are associated with this switch are disassociated.

Disabling the WLAN switch does not affect non-WLAN features on the switch, such as VLAN or STP functionality.

2.WLAN Switch Operational Status

Shows the operational status of the switch. The status can be one of the following values:

• Enabled
• Enable-Pending
• Disabled
• Disable-Pending

If the status is pending, click Refresh to refresh the screen.

3.WLAN Switch Disable Reason

If the status is disabled, this field appears and one of the following reasons is listed:

• None—The cause for the disabled status is unknown.
• Administrator disabled—The Enable WLAN Switch check box has been cleared.
• No IP Address—The WLAN interface does not have an IP address.
• No SSL Files—The D-Link Unified Switch communicates with the APs it manages by using Secure Sockets Layer (SSL) connections. The first time you power on the Unified Switch, it automatically generates a server certificate that will be used to set up the SSL connections. The SSL certificate and key generation can take up to an hour to complete.

If routing is enabled on the switch, the operational status might be disabled due to one of the following reasons:

• No Loopback Interface—The switch does not have a loopback interface.
• Global Routing Disabled—Even if the routing mode is enabled on the WLAN switch interface, it must also be enabled globally for the operational status to be enabled.

IP Address

This field shows the IP address of the WLAN interface on the switch. If routing is disabled, the IP address is the network interface. If routing is enabled, this is the IP address of the routing or loopback interface you configure for the Unified Switch features.

AP Authentication

Select the check box to require APs to be authenticated before they can associate with the switch.

AP MAC Validation

Select the database to use for AP validation.

• Local—If you select this option, you must add the MAC address of each AP to the local Valid AP database.
• RADIUS—If you select this option, you must configure the MAC address of each AP in an external RADIUS server.

Country Code

Select the country code for the country where your switch and APs operate.A popup window asks you to confirm the change.

Wireless regulations vary from country to country. Make sure you select the correct country code so that your WLAN system complies with the regulations in your country. Some WLAN modes, such as the Atheros modes, are not available in some countries.

Changing the country code disables and re-enables the switch. Any channel and radio mode settings that are invalid for the regulatory domain are reset to the default values.

The country code (IEEE 802.11d) is transmitted in beacons and probe responses from the access points.

From the CLI, you can view the same information that is available on the Wireless Global Configuration page with the show wireless command in Privileged EXEC mode. If you need to change the country code, you can view the list of available countries and their twoletter codes with the show wireless country-code command.

The CLI commands to set the country code and enable the WLAN switch are available in Wireless Config mode. To set the country code, enter country-code . To enable the WLAN switch, enter enable. The following example shows how to access Wireless Config mode, set the country code to Canada, and enable the WLAN switch.

(switch-prompt) #configure
(switch-prompt) (Config)#wireless
(switch-prompt) (Config-wireless)#country-code CA
(switch-prompt) (Config-wireless)#enable

After you perform the physical hardware installation, you need to connect the D-Link Unified Switch to the network. The default IP address of the switch is, and DHCP is disabled by default. If you want to enable DHCP on the switch or assign a different static IP address, you must connect to the switch and change the default settings.

You can connect to the switch through Telnet or a Web browser from a host on the network, or you can connect to the switch through the console port (RS-232 DCE). After you connect to the switch, you can provide network information or enable the DHCP client.

To connect to the D-Link switch from a host on the network, enter the default IP address of the switch ( into the address field of a Web browser or a Telnet client.

To connect to the console port and provide network information, use the following steps:

1. Using a null-modem cable, connect a VT100/ANSI terminal or a workstation to the console (serial) port.

If you attached a PC, Apple, or UNIX workstation, start a terminal-emulation program,such as HyperTerminal or TeraTerm.

2. Configure the terminal-emulation program to use the following settings:

– Baud rate: 115,000 bps
– Data bits: 8
– Parity: none
– Stop bit: 1
– Flow control: none

3. Press the return key, and the User: prompt appears.

Enter admin as the user name. There is no default password. Press ENTER at the password prompt if you did not change the default password.

After a successful login, the screen shows the (switch-prompt)> prompt.

4. At the (switch-prompt)> prompt, enter enable to enter the Privileged EXEC command mode. There is no default password to enter Privileged EXEC mode. Press ENTER at the password prompt if you did not change the default password.

The command prompt changes to (switch-prompt)#.

5. Configure the network information.

– To use a DHCP server to obtain the IP address, subnet mask, and default gateway information, enter network protocol dhcp.

– To use a BootP server to obtain the IP address, subnet mask, and default gateway information, enter network protocol bootp.

– To manually configure the IP address, subnet mask, and default gateway, enter network parms <ipaddress> <netmask> [<gateway>], for example:

network parms

The default gateway is an optional parameter, so you do not need to enter an address to execute the command.

To view the network information, enter show network.

6. To save these changes so they are retained during a switch reset, enter the following command:


Once the D-Link Unified Switch is connected to the network, you can use the IP address for remote access to the switch by using a Web browser or through Telnet or SSH.

Connecting the Switch to the Network

You can use any of the 1000BASE-T ports, 10GB ports, or fiber-optic ports to connect the D-Link Switch to your network. The type of port you use to connect the switch depends on your network requirements and the type of node to which you connect the Switch, which might be a hub, router, or another switch.

There is a great deal of flexibility on how connections are made using the appropriate cabling.

• Connect a 10BASE-T hub or switch to the Switch via a twisted-pair Category 3, 4 or 5 UTP/STP cable.

• Connect a 100BASE-TX hub or switch to the Switch via a twisted-pair Category 5 UTP/ STP cable.

• Connect 1000BASE-T switch to the Switch via a twisted pair Category 5e UTP/STPcable.

• Connect a switch supporting a fiber-optic uplink to the Switch’s SFP ports via fiber-optic cabling.

• Change the Switch to PoE mode using the Mode Select button. When in PoE Mode, the Switch works with all D-Link 802.3af capable devices.

The Link/Act LEDs for each UTP port will light green or amber when the link is valid. A blinking LED indicates packet activity on that port.

Connecting the Switch and AP Directly


You can connect one or more DWL-3500AP or DWL-8500AP access points directly to the Switch by using a straight-through or crossover UTP cable.

Connecting the Switch and AP through the L2/L3 Network


The Switch can discover and manage APs whether they are directly connected, connected through a device in the same subnet, or connected to different subnets.

Connecting to the Core Network

The optional 10GB ports on the DWS-3026 are ideal for uplinking to the core network.


Connections to the Gigabit Ethernet ports are made using a fiber-optic cable or Category 5e copper cable, depending on the type of port. A valid connection is indicated when the Link LED is lit.

7. Registration card & China Warranty Card (for China only)

If any item is missing or damaged, please contact your local D-Link Reseller for replacement.

Installation Guidelines

Please follow these guidelines for setting up the Switch:

• Install the Switch on a sturdy, level surface that can support at least 6.6 lb. (3 kg) of weight. Do not place heavy objects on the Switch.

• The power outlet should be within 1.82 meters (6 feet) of the Switch.

• Visually inspect the power cord and see that it is fully secured to the AC power port.

• Make sure that there is proper heat dissipation from the Switch and adequate ventilation around the Switch. Leave at least 10 cm (4 inches) of space at the front and rear of the Switch for ventilation.

• Install the Switch in a fairly cool and dry place for the acceptable temperature and humidity operating ranges.

• Install the Switch in a site free from strong electromagnetic field generators (such as motors), vibration, dust, and direct exposure to sunlight.

• When installing the Switch on a level surface, attach the rubber feet to the bottom of the device. The rubber feet cushion the Switch, protect the casing from scratches, and prevent it from scratching other surfaces.

Installing the Switch without the Rack

First, attach the rubber feet included with the Switch if installing on a desktop or shelf. Attach these cushioning feet on the bottom at each corner of the device. Allow enough ventilation space between the Switch and any other objects in the vicinity.


Installing the Switch in a Rack

The Switch can be mounted in a standard 19″ rack. Use the following diagrams as a guide.


Fasten the mounting brackets to the Switch using the screws provided.

Powering On the Switch

Plug one end of the AC power cord into the power connector of the Switch and the other end into the local power source outlet.

After powering on the Switch, the LED indicators will momentarily blink. This blinking of the LED indicators represents a reset of the system.

Power Failure

As a precaution, in the event of a power failure, unplug the Switch. When power is resumed, plug the Switch back in.

Installing the SFP ports


The D-Link DWS-3000 series switches are equipped with SFP (Small Form-factor Pluggable) ports,which are to be used with fiber-optical transceiver cabling in order to uplink various other networking devices for a gigabit link that may span great distances. These SFP ports support full-duplex transmissions, have auto-negotiation and can be used with DEM-310GT (1000BASE-LX), DEM-311GT (1000BASE-SX), DEM-314GT (1000BASE-LH) and DEM-315GT (1000BASE-ZX) transceivers. See the figure below for installing the SFP ports in the Switch.

Installing the Optional Modules

The rear panel of the D-Link DWS-3026 includes two open slots that may be equipped with the DEM-410X 1-port 10GE XFP uplink module, or a DEM-410CX 1-port 10GBASE-CX4 uplink module, both sold separately.

Adding the DEM-410X optional module allows the switch to transmit data at a rate of ten gigabits per second. The module port(s) are compliant with standard IEEE 802.3ae, support full-duplex transmissions only and must be used with XFP MSA-compliant transceivers.

The DEM-410CX uses copper wire medium, not optic fiber and therefore has a transmit length limit up to 1 meters. Compliant with the IEEE802.3ak standard, this module uses a 4-lane copper connector for data transfer in full-duplex mode.

To install these modules in the D-Link DWS-3026 Switch, follow the steps listed in this section.

CAUTION: Before adding the optional module, make sure to disconnect all power sources connected to the Switch. Failure to do so may result in an electrical shock, which may cause damage, not only to the individual but to the Switch as well.

At the back of the Switch to the left are the two slots for the optional modules. These slots must be covered with the faceplate if the slots are not being used. To install a module in an available slot, remove the faceplate by loosening the screws and pulling off the plate.

Install the Module

Unplug the Switch before removing the faceplate covering the empty slot. To install the module, slide it in to the available slot at the rear of the Switch until it reaches the back, as shown in the following figure. Gently, but firmly push in on the module to secure it to the Switch. The module should fit snugly into the corresponding receptors.


Now tighten the two screws at adjacent ends of the module into the available screw holes on the Switch. The upgraded Switch is now ready for use.

Connecting to the External Redundant Power System

The Switch supports an external redundant power system (RPS). The diagrams below illustrate a proper RPS power connection to the Switch. Please consult the documentation for information on power cabling and connectors and setup procedure.
