Error (Ping)

If the system is unreachable for any reason—host down, ICMP not running on host, route not configured,
intermediate router down, network down or congested, etc.—the Manager displays an Error screen with
the name of the tested host. To troubleshoot the connection, try to Ping other hosts that you know are
working.
