The following figure shows the location of the Ethernet Uplink and Switch ports on the product:
Because the LANs attached to each Digi Connect ES 4/8 SB with Switch are typically not connected to each other,
equipment can have static network addresses and be moved from one location to another without needing to be
reconfigured. The central data management system can easily communicate with the equipment by addressing the
appropriate Digi Connect ES 4/8 SB with Switch device. The Digi Connect ES 4/8 SB with Switch uses NAT and port
forwarding to make the connection.
Assuming the network topology just described, here are the steps for configuring the Ethernet interfaces of each
Digi Connect ES 4/8 SB with Switch device for installation. These steps apply to a single Digi Connect ES 4/
8 SB with Switch and its connected Ethernet and serial devices, and must be performed for each Digi Connect ES 4/
8 SB with Switch deployed.
1. Connect a laptop to one of the Ethernet Switch ports on the Digi Connect ES 4/8 SB with Switch and open the web
interface.
The recommended Ethernet IP address settings for the laptop are:
IP Address: 192.168.1.99
Subnet: 255.255.255.0
Default Gateway: 192.168.1.1
2. In the web interface, go to Configuration > Network > Ethernet Switch IP Settings. page. This page assigns IP
address numbers for devices connected to the Ethernet Switch. It is recommended that you leave the settings
here as-is. The IP address for the Ethernet Switch on the unit is set to 192.168.1.1. You can set fixed IP addresses
starting at 192.168.1.2, 192.168.1.3, and so on. The DHCP server assigns 192.168.1.101 and higher for devices that
have their IP addresses dynamically assigned.
3. Choose an IP address assignment mechanism and strategy for the uplink interface. Use one or the other of these
assignment mechanisms:
Assign an IP address in the DHCP configuration file in the network's DHCP server. In this case, no configuration

change on the Digi device is necessary. The device will request a DHCP address from any visible DHCP server at
startup.
Or, in the command line interface, type the following:
set network if=eth1 dhcp=on static=off autoip=off
Where eth1 is the network interface of the uplink. The autoip=off option avoids unintentional network address
problems through automatic IP address assignment if DHCP servers are temporarily unavailable.
Assign a static IP address. In the web interface, go to Configuration > Network > Ethernet Uplink IP settings

and type the static IP address.
