Introduction
1.2.2Address Labels
| Each Quantum Ethernet web embedded server module has two address labels. |
| One identifies the Ethernet or MAC address. The other label allows you to record |
| the module’s Internet Protocol (IP) network address. |
Ethernet | The Ethernet address or MAC address is assigned at the factory and is recorded |

| global assigned address. It is set in PROM. The Ethernet address is recorded on |
| the label in hexadecimal, in the form 00.00.54.xx.xx.xx. |

The IP address comes from one of three places in the following order:
The configured address
zAn address from a BOOTP server Derived IP network address
You can use the derived address, which is calculated from the Ethernet address set by the factory. You can also configure a unique address via Modsoft or Concept. Throughout this book, these alternatives will be referred to as the derived IP network address and a
The IP network address has the form xxx.xxx.xxx.xxx, where each group xxx is a decimal number from 0 to 255. A space is provided for recording this address on the label inside the front door panel of the module.
If you will be operating on an open network, you should opt for a
If you will be operating on a local network, you may use the derived IP network address. However, you should check with your network administrator first to ensure that this address is not already in use.
To calculate the derived IP network address, convert the rightmost eight digits of the Ethernet address from hex to decimal. They will take the form 84.xxx.xxx.xxx, where each group xxx is a decimal number from 0 to 255.
