Moxa Technologies 5110 Series Initializing NPort 5110’s IP Address, Factory Default IP Address

NPort 5110 Series User’s Manual Initial IP Address Configuration

Initializing NPort 5110’s IP Address

1.Determine whether your NPort 5110 needs to use a Static IP or Dynamic IP (either DHCP or BOOTP application).

2.If NPort 5110 is used in a Static IP environment, you can use NPort 5110 Administration Suite, ARP, Web Console, Telnet Console, or Serial Console to configure the new IP address.

3.If NPort 5110 is used in a Dynamic IP environment, you can use NPort 5110 Administration Suite, Web Console, Telnet Console, or Serial Console to configure NPort 5110 to get an IP address dynamically with DHCP, DHCP/BOOTP, or BOOTP.

ATTENTION

Consult your network administrator on how to reserve a fixed IP address for your NPort 5110 in the MAC-IP mapping table when using a DHCP Server or BOOTP Server. In most applications, you should assign a fixed IP address to your NPort 5110.

Factory Default IP Address

NPort 5110 products are configured with the following default private IP address:

Default IP address: 192.168.127.254

(IP addresses of the form 192.168.xxx.xxx are referred to as private IP addresses, since it is not possible to directly access a device configured with a private IP address from a public network. For example, you would not be able to ping such a device from an outside Internet connection. NPort 5110 applications that require sending data over a public network, such as the Internet, require setting up the server with a valid public IP address, which can be leased from a local ISP.)

NPort 5110 Administration Suite

NPort 5110 Administration Suite consists of some useful utility programs that are used to configure and manage your NPort 5110s.

See Chapter 5 for details on how to install NPort 5110 Administration Suite, and how to use this suite of useful utilities to set up IP addresses and configure your NPort 5110 serial device servers.

ARP

You can make use of the ARP (Address Resolution Protocol) command to set up an IP address for your NPort 5110. The ARP command tells your computer to associate the NPort 5110’s MAC address with the intended IP address. You must then use Telnet to access the NPort 5110, at which point the device server’s IP address will be reconfigured.

ATTENTION

In order to use the ARP setup method, both your computer and NPort 5110 must be connected to the same LAN. Or, you may use a cross-over Ethernet cable to connect the NPort 5110 directly to your computer’s Ethernet card. Your NPort 5110 must be configured with the factory default IP address—192.168.127.254—before executing the ARP command, as described below.
