5.4 Configuring the SC-COM for the Local Network
5.4.1 Information on Integrating the SC-COM into a Local Network
You can also change the network settings of the SC-COM using the XML file custom.xml (see Section 6.3
"Customer-Specific Settings via XML File", page 24).
5.4.2 Configuring the SC-COM for a Static Network
The SC-COM has three LAN interfaces for connected nodes.
Procedure:
1. Log in on the user interface.
2. Select Sunny Central > Settings > Network.
3. In the field IP address, enter the static IP address that you want to use to access the SC-COM in the local network.
4. Enter the subnet mask of your network in the field Subnet mask.
5. Enter the gateway IP address of your network in the field Gateway address. Usually, the IP address of the router
has to be entered here.
6. Enter the IP address of the DNS server (Domain Name System) in the field DNS server address. Usually, the IP
address of the router has to be entered here.
7. Select [Save] and [Confirm].
5.4.3 Configuring the SC-COM for Dynamic Networks
The SC-COM can obtain the network settings from a DHCP server. The IP address, subnet mask, gateway and DNS server
are automatically obtained from the DHCP server when the SC-COM is started.
Procedure:
1. Log in on the user interface.
2. Select Sunny Central > Settings > Network.
3. Enable DHCP in the field IP address.
4. Select [Save].
Protecting the Ethernet network from external attacks
Secure your Ethernet network from external threats by means of appropriate safety measures such as a firewall and
the allocation of secure passwords.
Network Factory-set IP address
LAN1: Service interface of the Sunny Central 192.168.100.2*
* This IP address cannot be changed.
LAN2: Control network 172.24.1.51
LAN3: Monitoring network 172.16.1.51
Using DHCP
Before setting the SC-COM to dynamic IP address assignment, check your DHCP server. The DHCP server must
extend the lease of the assigned IP address. Do not use the DHCP server if it assigns a new IP address after the lease
has expired. DHCP servers can normally list all devices to which you have assigned an IP address. You can then
identify the SC-COM based on your MAC address. The MAC address of your SC-COM can be found on the type
label or by selecting Sunny Central > Info on the user interface.
