For the routed packet, if the destination is not in the routing table, all the traffic is put into the device with the

designated IP address, known as the default router. Only the switch uses the gateway setting for Trap Events

Host.

When assigning an IP address to the switch, first check to see what an existing switch on the same network uses

as a network address. Use the same network address and append your host address to it.

Once you type in the username and password in the login screen, the IP Configuration screen appears.

Options in this screen include DHCP Setting, IP Address, Subnet Mask, Default Gateway, DNS Server, and the

Apply button.

Type in the IP address in the format 192.168.1.xon your PC.

For the subnet mask, enter 255.255.255.0. Any subnet mask such as 255.255.255.x is allowed.

The Domain Name Server translates a human-readable machine name to an IP address. Every machine on the

Internet has a unique IP address. A server generally has a static IP address. To connect to a server, the client

needs to know the server's IP. However, a user generally uses the name to connect to the server. Thus, the

switch DNS client program (such as a browser) will ask the DNS to find the named server's IP address.

The LGB201A implements 24 Fast Ethernet TP ports with auto MDIX and 2 Gigabit dual media ports with SFP

for removable module supported comprehensive fiber types of connection, including LC, BiDi LC for SFP.

Use the switch for the following applications.

• FTTB (Fiber To The Building)/FTTO (Fiber To The Office) application is used in carrier or ISP (see

Figure 3-10).

• FTTH (Fiber To The Home) application is used in carrier or ISP (see Figure 3-11).
