Any configuration changes made locally on the switch won't be synchronized with Sophos Central. We recommend making changes from the Sophos Central control panel instead.

Connecting the switch to a network

All Sophos Switch models have a default IP address of 172.16.16.239. When you first connect your switch to a network, you must connect a computer to it to assign it a new IP address in your network. If you have a DHCP server, you can use that to assign an IP address to the switch. You can assign a static IP address to the switch if you don't have a DHCP server.

Click the appropriate tab for instructions for connecting a switch to your network.

To configure a switch using DHCP, do as follows:

  1. Connect the supplied power cord to the switch and plug the other end into an electrical outlet. Verify the switch's LED power indicator light is on.
  2. Wait for the switch to start. It might take a few minutes.
  3. Connect a computer to an Ethernet port on the switch.

  4. Configure the computer with a static IP address on the 172.16.16.0/24 network.

    Example

    IP address: 172.16.16.200

    Subnet mask: 255.255.255.0

  5. Open a web browser on your computer.

  6. In the web browser's address bar, enter the default IP address of the switch, 172.16.16.239, and press Enter. A login screen appears.

  7. Enter the switch's current password and click Login.

    The default username is admin, and the password is printed on a sticker on the switch's back panel.

    Tip

    To increase security, we highly recommend changing the admin password to something more unique or creating a new admin user. See People.

  8. Go to Configure > System settings > IP address settings and click IPv4 management.

    Tip

    You can also configure the switch with an IPv6 address. See IPv6 management.

  9. For Configuration, select DHCP.

  10. Click Apply to save the settings.
  11. Connect the switch to your network.
  12. On the DHCP server, find and write down the IP address allocated to the device. You'll need this IP address to access the management interface.

If your network doesn't have a DHCP server, you must assign a static IP address to your switch to connect to the web-based management interface. Do as follows:

  1. Connect the supplied power cord to the switch and plug the other end into an electrical outlet. Verify the switch's LED power indicator light is on.
  2. Wait for the switch to start. It might take a few minutes.
  3. Connect a computer to an Ethernet port on the switch.

  4. Configure the computer with a static IP address on the 172.16.16.0/24 network.

    Example

    IP address: 172.16.16.200

    Subnet mask: 255.255.255.0

  5. Open a web browser on your computer.

  6. In the web browser's address bar, enter the default IP address of the switch, 172.16.16.239, and press Enter. A login screen appears.

  7. Enter the switch's current password and click Login.

    The default username is admin, and the password is printed on a sticker on the switch's back panel.

    Tip

    To increase security, we highly recommend changing the admin password to something more unique or creating a new admin user. See People.

  8. Go to Configure > System settings > IP address settings and click IPv4 management.

    Tip

    You can also configure the switch with an IPv6 address. See IPv6 management.

  9. For Configuration, select Static.

  10. Configure the following settings:

    • Address: The IP address you want the switch to use.
    • Subnet mask: The subnet mask for your network.
    • Default gateway: The IP address of the default gateway for your network.
    • DNS server 1: The IP address of your primary DNS server.
    • DNS server 2: The IP address of your secondary DNS server.

  11. Click Apply to save the settings.

  12. Connect the switch to your network.
