Users may encounter situations where they are unable to access their switch. Troubleshooting this process has several phases:

  1. Confirmation of a managed switch
  2. Computer connection check
  3. IP Address check
  4. Switch configuration check
  5. RMA criteria

Confirmation of a Managed Switch

The instructions in this document apply only to the EL 212 and EL 228 switches

Computer Connections Check

To ensure that you are properly connected to the switch, use the following steps:

  1. From the Start menu, open the Control Panel.
  2. Double-click on Network Connections.
  3. Double-click on the Adapter that is connected to your Sixnet switch.
  4. The connection status should be listed as Connected or as Limited or no connectivity. If this is the case, proceed to Phase 3. If the connection status is listed as Disconnected, proceed to step 5.
  5. Confirm that the cable is physically seated in the network (LAN) port of your computer. Remove and reseat the cable. A click should be heard when the cable is properly seated. If a link is established, the LEDs next to the port should be lit or flashing.
  6. Confirm that the cable is physically seated in an Ethernet port of the switch. Remove and reseat the cable. A click should be heard when the cable is properly seated. If a link is established, the LEDs next to the port should be lit or flashing. Also try another port of the switch if no link is detected.
  7. Try another Ethernet cable, if one is available.
  8. Restart your computer.
  9. Try another PC, if one is available.
  10. If there are still no Link indications, proceed to Phase 5 for RMA Criteria.

IP Address Check

To set your IP address, or to check your current IP address, use the following steps:

  1. From the Start menu, open the Control Panel.
  2. Double-click on Network Connections.
  3. Click on the Adapter that is connected to your Sixnet switch to highlight it. Right click to display the popup menu and choose Properties.
  4. In the General tab, scroll through the list of items that the connection uses until you reach the Internet Protocol (TCP/IP) item. Click on it, and then click the Properties button.
  5. If a static address has been configured, it will be listed here. To configure one or to change the existing address, proceed to step 6.
  6. Click the Use the following IP address button.
  7. Enter the desired IP address, subnet mask and gateway (if known) in the appropriate fields.
  8. This information should be similar to the IP address of the Sixnet device you wish to communicate with. For example, if the switch is configured for 192.168.0.1 with a subnet mask of 255.255.255.0, your computer should be set to an unused address in the same range, such as 192.168.0.100, with the same subnet mask.
  9. The DNS settings should be blank, unless your network administrator has provided these values for you.
  10. Click OK in the TCP/IP properties window, then OK again in the Connection properties window.
  11. Your IP address has now been set.

EL Series Switches

All EL switches shipped before May 2010 have a default IP address of 10.2.0.1. Any switches shipped after this time have a default IP address of 192.168.0.1

Switch Configuration Check

To ensure that a setting in your switch is not preventing you from accessing it, do the following:

  1. You must be able to access the console port of the switch using an RS232 connection.

Access the Terminal User Interface

To access the terminal user interface, do the following:

  1. Connect the serial port of your PC (typically a female DB9 connector) to the serial port of the switch. Refer to the hardware user manual for details on how to make this connection.
  2. Configure a terminal program (such as HyperTerminal) for 9600, 8N1 and no flow control. Once connected, pressing enter will produce a login prompt.

Using the CLI

  1. Log in with the username admin and password admin.
  2. Type show ip interface to view the current IP address and subnet mask
  3. To change the switch’s address, type config and press enter to enter configuration mode. Then type interface vlan 1 to select the default management vlan of 1. Finally, type ip address xx.xx.xx.xx yy.yy.yy.yy where xx is the desired IP address and yy is the desired subnet mask. Type end to exit configuration mode.
  4. Type show vlan id 1 and confirm that the port you are connected to is listed.
  5. If the port you are connected to is not listed, you can move to another port that is listed, or add the port to VLAN 1. To do so, type config and press Enter to enter configuration mode. Then type interface ethernet 1/xx where xx is the port number you wish to add to the management vlan. Next, type switchport allowed vlan add 1 untagged to add the port to the management vlan. Type end to exit configuration mode.
  6. Type show vlan id 1 and confirm that the port you added is now listed.
  7. You should now be able to ping the IP address of the switch and access it using the web interface.
  8. If you are still unable to access the switch, you may need to restore the switch to the factory defaults. To do so, type config to enter configuration mode, then type boot system config:Factory_Default_Config.cfg
  9. Finally, to restart the switch in the factory default configuration, type end to exit configuration mode and type reload to restart the switch.
  10. After the switch has rebooted, you should now be able to ping the IP address of the switch and access it using the web interface. If you are unable to do so, proceed to phase 5 for RMA criteria.

RMA Criteria

If you have proceeded through the steps above and are still unable to access your switch, you may need to send your switch back to Sixnet for evaluation. Please have the following information for each unit to be returned before requesting an RMA:

  • Complete part number
  • Serial number and/or date code
  • Description of the fault

It should also be indicated in the case/ticket if the customer is requesting advanced replacement. Once the information has been gathered, assign the case to the RMA department.
