These steps allow changes in the TCP/IP settings for the platform to configure the IP address and TCP port parameters for the remote controller.
- Prerequisites: You are stepping through the Commissioning Wizard.
- To change the Host Name, enter the new name.
If a Host Name is entered, typically the name is unique for the domain. In some installations, chang- ing Host Name may result in unintended impacts on the network, depending on how the DHCP or DNS servers are configured. If in doubt, leave Host Name at its default setting.
- To change the contents of the Hosts File, click the control
.
- The file opens.
The format of this file is a standard TCP/IP hosts file, where each line associates a particular IP address with a known Hosts File. Each entry should be on an individual line. The IP address should be placed in the first column, followed by the corresponding Host Name. The IP address and the Host Name should be separated by at least one space. The Undo Changes button resets all set- tings (all Interfaces) back to the original pre-step values.
- To add a new line, click at the end of the last line, press Enter and type the required data on the new line.
- To enable use of IPv6, click the check box and configure any applicable IPv4 and IPv6 settings.
- Use IPv6 limits the station to receive only IPv6 requests.
- Review the Interface 1 settings and do one of the following: (a) If you are enabling more than one LAN port (applicable to LAN1, LAN2, and WiFi) then the IP address for each must be configured on different subnets, otherwise the ports will not function correctly. For example, with a typical Class C subnet mask of 255.255.255.0, setting Interface 1= 192.168.1.99 and Interface 2=192.168.1.188 is an invalid configuration, as both addresses are on the same subnet. (b) Click IPv4 Settings tab, which includes the temporary factory-shipped IP address. Assign the SLX a unique IPv4 address for the network you are installing it on. No other device on this net- work should use this same IP address. Include the appropriate subnet mask used by the network. (c) If the network supports DHCP, you can enable it (click DHCP Enabled). In this case, the IP ad- dress and subnet mask properties become read only. in general (for stability, static IP addressing is recommended over DHCP. If DHCP is preferred, an IP Address Reservation should be entered for the controller in the DHCP Server. The controller IP address should not change. If your SLX has a wireless option that you plan to use for enterprise network connections, do not enable DHCP here. Instead, you need to configure the WiFi adapter for SLX DHCP as de- scribed in the appropriate controller WiFi Guide, for example SLX-8000 WiFi Guide.
- Review the Interface 2 details.
SLX-8000 and SLX-9000 controllers have two Ethernet ports, where Interface 2 is available for configuring the secondary (LAN2) Ethernet port. By default, this port is disabled, that is without a default address. The intended usage for this port, as for the secondary LAN port, as follows:
To isolate a driver’s Ethernet traffic from the primary (LAN1) interface, or to create a private network by daisy chaining multiple IP devices off of the controller’s secondary LAN port. This scenario requires that you configure the LAN2 port as a DHCP server in the DHCPDv4 Settings tab.
In some cases, LAN2 may be set up with a standard, fixed, IP address that is used only by a company’s service technician, when on site. This allows access to the controller without disconnecting it from the customer’s network, or without connecting the technician’s service PC to the customer’s network (which might go against local IT security policies). If enabling LAN2, you must specify another (network) static IP address and the appropriate sub- net mask, that is a different subnet mask for each enabled LAN port IP address.
The controller does not provide IP routing or a bridging operation between different Interfaces (LAN ports or WiFi).
- To enable the secondary Ethernet port Interface 2, expand Interface 2 and select the Adapter Enabled check box.
- To set up the secondary Ethernet port (Interface 2) as a DHCP client, select the Enabled check box on the IPv4Settings tab.
- Make sure that the DHCPDv4 is not enabled on the DHCPDv4 Settings tab.
- To set up the secondary Ethernet port (Interface 2) as a DHCP server, make sure that the DHCP check box is not selected on the IPv4 Settings tab, configure the port with a static IP address, and configure the properties in DHCPDv4 Settings. For example: Subnet: 192.168.111.0 Netmask: 255.255.255.0 Client range low: 192.168.111.15 Max. number of clients: 10
Based on the example above, client IP pool is 192.168.111.15 to 192.168.111.24
Default Lease Time (in hours, minutes, and seconds) configures the a DHCPIP address lease. Before it expires, the lease must be renewed.
Max Lease Time (in hours, minutes, and seconds), configures a DHCPIP address lease.
Subnet defines the subnet of IP addresses assigned by the DHCP server. Configure this to as- sign addresses on a different subnet than that used in other LAN or Access Point configura- tions, otherwise the ports will not function correctly.
Netmask defines the IP addresses assigned by the DHCP Server.
Client Range Low defines the lowest IP address for the range. The order of assigning IPs from the Access Point DHCP is indeterminate.
The adapter IP should be in the same subnet, but not in the range of addresses defined here.
Max Number of Clients defines the maximum number of clients that can attach at a given time.
- Under IPv4 Settings tab, enter the IPv4 address and subnet mask.
For example,
IPv4 Address: 192.168.111.1
IPv4 subnet mask: 255.255.255.0
Make sure that the secondary Ethernet port’s (Interface 2) IP address is outside the DHCP server’s client IP pool.
- To disable a DHCP server running on the secondary Ethernet port (Interface 2): Under DHCPDv4 Settings Tab, uncheck the DHCPDv4 check box. For the network settings to take effect, save and reboot the controller.
- To continue, click Next.
- The System Passphrase step opens.
