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.
