C. Replace
xxyy
with the last four digits of the hardware address. Use only
valid hexadecimal digits (0-9, A-F); do not use the hyphens that separate
the numbers. (You will find the hardware address on a label affixed to
the printed circuit board of the Ethernet PLC-5 controller.)
3. Save, close, and make a backup copy of this file.
Based on this configuration, the
BOOTPTAB
file looks like:
Run your BOOTP utility to send the configuration information to the
Ethernet interface module.
EXAMPLE
In this example there are three Ethernet PLC-5 controllers
and an HP 9000 personal computer. The names and
hardware addresses are device specific:
