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
ou to record
the module’s Internet Protocol
IP
network address.
Ethernet
Address Label
The Ethernet address or MAC address is assi
ned at the factor
and is recorded
on a label
on the front panel, above the cable connector.
This is a uni
ue 48-bit
lobal assi
ned 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 followin
order:
The confi
ured address
An address from a BOOTP server
Derived IP network address
You can use the derived address, which is calculated from the Ethernet address
set b
the factor
. You can also confi
ure a uni
ue address via Modsoft or
Concept. Throu
hout 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
roup xxx is a
decimal number from 0 to 255. A space is provided for recordin
this address on
the label inside the front door panel of the module.
If
ou will be operatin
on an open network,
ou should opt for a user-confi
ured
address. Obtain a valid address from
our network administrator.
If
ou will be operatin
on a local network,
ou ma
use the derived IP network
address. However,
ou should check with
our network administrator first to ensure
that this address is not alread
in use.
To calculate the derived IP network address, convert the ri
htmost ei
ht di
its of
the Ethernet address from hex to decimal. The
will take the form 84.xxx.xxx.xxx,
where each
roup xxx is a decimal number from 0 to 255.
