1.2.2 Address 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
Address Label The Ethernet address or MAC address is assigned at the factory and is recorded
on a label on the front panel, above the cable connector. This is a unique 48-bit
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.
Internet Protocol
(IP) Network
Address Label The IP address comes from one of three places in the following order:
z The configured address
z
An address from a BOOTP server
z
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 user-configured address.
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 user-configured
address. Obtain a valid address from your network administrator.
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.
