The user has changed the NPort 6000 series device
server's IP address. When the IP address changes,
the NPort 6000 series device server will send an
e-mail with the new IP address before it reboots.
If the NPort 6000 series device server is unable to
send an e-mail message to the mail server within 15
seconds, it will reboot anyway, and abort the e-mail
auto warning.
