Change network setting
When you press "2 ENTER" in the main configuration interface, initially it will ask whether to use DHCP
protocol to assign IP address. If you would like to use DHCP protocol to assign IP address, then select
"Y". Otherwise, select "N". GTT-030 support getting IP address through DHCP, but it always need a
static IP address because the server needs to supply the network timing service to other devices. As a
result, in DHCP network system, the recommended configuration is to assign a static IP address from
the IP Pool of DHCP server
to GTT-030. Other devices can use the static IP to access GTT-030.
When it asks whether to use DHCP, If you select "N", it will prompt to enter the server IP address, subnet
mask and gateway IP address. Finally it will prompt whether to modify the network configuration in
accordance with settings entered, then select "Y" and it will change the equipment configuration. This
configuration can not take effect until rebooting the server. So we need to restart the server. We can
modify the network configuration for many times before restarting the equipment, but only the last one
can take effect. The configuration interface is shown in Figure 4.
