1-4 Product Overview
After out-of-box power-up, the most common reason for a flashing
red fault LED is because an IP address has not yet been assigned via
BOOTP. Either set up a BOOTP server to assign an IP address or
modify the ENI/ENIW configuration to use a specific IP address or to
obtain an IP address via a DHCP server.
For more detailed information on LED operation, see Chapter 9,
Troubleshooting.
