Single port KVM over IP switch
59
Configuration or console login
Do not use the serial port for any special function, use it only for the initial configuration
(see Table 4-1 ).
Modem
The IP-KVM switch offers remote access using a telephone line in addition to the
standard access over the built-in Ethernet adapter. The modem needs to be connected to
the serial interface of the IP-KVM switch .
Logically, connecting to the IP-KVM switch using a telephone line means nothing else
than building up a dedicated point-to-point connection from your console computer to the
IP-KVM switch. In other words, the IP-KVM switch acts as an Internet Service Provider
(ISP) to which you can dial in. The connection is established using the Point-to-Point
Protocol (PPP). Before you connect to the IP-KVM switch, make sure to configure your
console computer accordingly. For instance, on Windows based operating systems you
can configure a dial-up network connection, which defaults to the right settings like PPP.
The Modem Settings panel allows you to configure the remote access to the IP-KVM
switch using a modem. The meaning of each parameter will be described below. The
modem settings are part of the serial settings panel.
Serial line speed
The speed the IP-KVM switch is communicating with the modem. Most of all modems
available today will support the default value of 115200 bps. In case you are using an
old modem and discovering problems try to lower this speed.
Modem Init String
The initialization string used by the IP-KVM switch to initialize the modem. The default
value will work with all modern standard modems directly connected to a telephone
line. In case you have a special modem or the modem is connected to a local
telephone switch that requires a special dial sequence in order to establish a
connection to the public telephone network, you can change this setting by giving a
new string. Refer to the modem's manual about the AT command syntax.
Modem server IP address
This IP address will be assigned to the IP-KVM switch itself during the PPP
handshake. Since it is a point-to-point IP connection virtually every IP address is
possible but you must make sure, it is not interfering with the IP settings of the
IP-KVM switch and your console computer. The default value will work in most cases.
Modem client IP address
This IP address will be assigned to your console computer during the PPP
handshake. Since it is a point-to-point IP connection virtually every IP address is
possible but you must make sure, it is not interfering with the IP settings of the
IP-KVM switch and your console computer. The default value will work in most cases.
