Unable to connect to the ENC using its IP address

Issue

Unable to connect to the ENC using its IP address. The ENC Ethernet port LED's appear to indicate normal operation. 

Environment

I/A Series Enterprise Network Controller

Cause

The ENC DHCP function was enabled by mistake on a system that does not have a DHCP server. The ENC when booted up will try to get an IP address from a DHCP server which does not exist and the ENC may not have a valid IP address. 

Resolution

Connect to the ENC via its serial shell and perform the following procedure. Refer to Lesson Learned article #5623 for details on connecting to the ENC serial shell.

1. Connect to the ENC serial shell using Windows HyperTerminal. Allow the ENC to boot up completely and you should see output messages similar to the following.
