Software Release 4.1
8.4.1 IP Configuration Parameters
The IP Configuration page provides the following parameters:
LAN1 Network Interface Configuration, IP Address
The operator enters the non-routable IP address that will be associated with the Ethernet
connection on this module. (The default IP address from the factory is 169.254.1.1.) If the operator-
assigned IP address is forgotten, then the operator must both
1. physically access the module.
2. use an override plug to electronically access the module configuration parameters at
169.254.1.1. See Overriding IP Address and Password Setting on Page 66.
LAN1 Network Interface Configuration, Subnet Mask
The operator enters an appropriate subnet mask for the module to communicate on the network.
The default subnet mask is 255.255.255.0. See General IP Addressing Concepts on Page 58.
LAN1 Network Interface Configuration, Gateway IP Address
The operator enters the appropriate gateway for the module to communicate with the network. The
default gateway is 169.254.0.0.
LAN2 Network Interface Configuration (RF Private Interface), IP Address
The operator should not change this parameter from the default AP private IP address of
192.168.101.1. A flat Class C subnet is used to communicate with each of the SMs that are
registered. The AP uses a combination of the private IP and the LUID (logical unit ID) of the SM.
For example, if an SM is the first to register in an AP, and another SM registers later, then the AP
whose Private IP address is 192.168.101.1 uses the following SM Private IP addresses to
communicate to each:
SM LUID Private IP
First SM registered 2 192.168.101.2
Second SM registered 3 192.168.101.3
If the private IP address of the AP is changed, then the new address must
• designate a Class C subnet that is not used for anything else.
• have the form xxx.xxx.xxx.1, where 1 is the value of the last octet of the address.
NOTE: An SM is not required to have an operator-assigned IP address where space is limited for
subnet allocation. The SM is directly accessible without an LUID if either the SM Color Code
parameter is set to 0 or the AP has a direct Ethernet connection to the SM.
8.4.2 IP Configuration Buttons
The IP Configuration page provides the following buttons:
Save Changes
When the operator clicks this button, any changes that have been made on the Configuration page
are recorded in flash memory. However, these changes do not apply until the next reboot of the
module.
