PPP Mode
There are three PPP options: “Disabled,” “Server” and “Client.”
• Disabled is the default setting.
• Server is for a connecti on request from a peer computer. It allows users to connect to your
servers without the Internet understructure, and it can be us ed as a backup access in case
of Internet failure or an ultra-secure access by the use of private lines and mod ems.
• Client is for a dial-in connect ion to a PPP server (your ISP or an enterprise PPP server). It
can be used when there is no LAN or router available for direct Internet access using a modem.
NOTE 1: The PPP connection can work simultaneously with the lAN connection. NOTE 2: The
PPP connection uses the same serial interface as Power Manage ment: As these two features
are mutually exclusive, by enabling the PPP you automatically disable Power Management
and vice versa.
If you have a lAN connection, normally you don’t have to choose the PPP connect ion as your
connection mode. However, if no LAN connection is available, you can enable either t he PPP
Server mode or the PPP Client mode according to the real connec tion scenarios.
PPP Server Settings
Current Local IP Address: This displays the IP address of the switch when a PPP c onnection
is established. If the PPP connection is not yet established, however, the IP address will
show as “Unknown.” NOTE: This address is normally the same as the local IP Address
entry, but must be distinct from the one that is used by the switch on the LAN.
Local IP Address: Enter the IP address (default = 192.168.2.200) to be used by the switch in
the PPP connection. This IP address will be used only in PPP connectio ns by the switch
alone, and should be distinct from the IP address (default = 192.168.1.200) that is specied
on the lAN TCP/IP screen and used for connection via direct lo cal area network.
