Issue
Unable to connect to the ENC using its IP address. The ENC Ethernet port LED's appear to indicate normal operation.
Product Line
TAC IA Series
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 Serial connection to I/A Series G3 ENC serial system shell using Windows HyperTerminal 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.
