Server configuration debugging
GTT-030 network time server can conduct maintenance and management through the local serial cable
connection or the remote telnet connection. The local connection needs to use a cross serial cable with
connectors on both sides (that is, 2,3 feet of the two sides are cross connected). The management is
carried out on the super terminal. The serial port configuration parameters of the super terminal are as
shown in Figure 3-1. Under the remote telnet connection, you only need to enter: telnet <IP address of
the server> under the command-line. The following example describes the maintenance methods with
local connection, so does remote maintenance.
