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 PS/2 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 PS/2 IP-KVM switch .
Logically, connecting to the PS/2 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 PS/2 IP-KVM switch. In other words, the PS/2 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 PS/2 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 PS/2
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 PS/2 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 PS/2 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 PS/2 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 PS/2
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 PS/2
IP-KVM switch and your console computer. The default value will work in most cases.
