Your NOE BOOTP Server
Your NOE x0 module comes supplied with a BOOTP Server. This feature allows you
to provide IP addresses to all the I/O devices being serviced by the NOE771x0.
Providing a BOOTP Server that is built into your NOE771x0 module eliminates the
need for you to have a dedicated PC on your I/O network acting as a BOOTP Server.
NOTE: The NOE771x0’s BOOTP Server cannot be used to provide its own IP
address.
You can configure your NOE771x0’s BOOTP Server from the module’s HTTP Web
page. Using this feature allows you to add, remove, and edit devices to the BOOTP
Server’s database, which is maintained on the modules non-volatile memory.
DHCP Server
NOTE: The DHCP Server is available on the 140NOE771x1 models.
Dynamic Host Configuration Protocol (DHCP) is a superset of the BOOTP Protocol.
Your 140NOE771x1 has a DHCP Server. The DHCP Server is compliant with RFC
1531. The DHCP Server can be used to provide the IP configuration to devices
using BOOTP or devices using DHCP.
The DHCP Server has entries that use the MAC address to serve the IP
configuration and entries in the Server that use the role name to serve the IP
configuration. See the Address Server Configuration/Faulty Device Replacement
chapter in the Quantum NOE 771 xx Ethernet Modules User Guide for details on
configuring your NOE’s address Server.
If you are migrating a BOOTP configuration from a 140NOE771x0 module to the
new 140 NOE 771 x1 module, see the Address Server Configuration/Faulty Device
Replacement chapter in the Quantum NOE 771 xx Ethernet Modules User Guide for
details on automatic upgrade of your configuration for the new DHCP Server.
NOTE: OPERATING ON A CORPORATE NETWORK
Before placing the NOE on a corporate network, Schneider Automation
recommends that you discuss the installation with your MIS department. It is likely
that your company’s corporate network has at least one DHCP Server running
already. If the NOE’s DHCP Server is running on the same network, it may disturb
the network.
To avoid any possible problem related to the NOE’s DHCP Server on the corporate
network, you must ensure that the DHCP Server is not running in the NOE by not
having address entries in the configuration. If there are no configured devices in the
address Server configuration page, then the NOE will not start the DHCP Server.
