4.1.4 Access
Options
The AI-SRVR can be accessed through its Ethernet port or its console (serial) port.
Initially, the unit must be configured so that its IP address is set to a value placing it on
the same subnet as that in which it is being installed. The
simplest
way to do this is via
the console port. If a null-modem cable is not available, the unit can also be configured
via its Ethernet port and a Telnet session as described in Section 4.1.4.4.
4.1.4.1 HyperTerminal
©
Later versions of HyperTerminal can connect to the AI-SRVR in either
of two ways
:
by Telnet or the unit’s console port using a null-modem
cable (not provided). Earlier versions of HyperTerminal did not have
Telnet capability. Once a connection is made, either method of access
involves the
same procedure
and displays the
same screens
.
4.1.4.2 Console
Port
Access
With a serial null-modem cable connected between the unit’s COM1 (DB-9) port and a
computer terminal (or a computer performing terminal emulation), the unit can be
monitored and configured. For proper EIA-232 communication
:
•
Set the Baud rate to 57600.
•
Set the Data bits to 8.
•
Set the Parity to None.
•
Set the Stop bits to 1.
•
Set the Flow control (handshaking) to None.
•
Set Emulation to ANSI.
With console port access, no login is required. As soon as the unit boot-up process is
completed and the serial cable is connected, the screen will display the statistics screen
for the most recently used function — AI-SRVR or AI-PROXY.
4.1.4.3 Telnet
Access
The AI-SRVR includes a Telnet server. It is factory-programmed with a default IP
address of 192.168.92.68 and a Class C subnet mask of 255.255.255.0. Changing the
IP address is strongly encouraged. Once the AI-SRVR has finished booting and its
Ethernet port has been connected to the Ethernet network, Telnet communications are
possible. However, the AI-SRVR and any computer communicating with it must share
the
same subnet
. If they are not on the same subnet, they can not communicate.
