Installation and Initial Configuration Guide

Access Methods

The IBM 2212 software must be configured as part of the installation process. Therefore, you have to access the software in one of the following ways:

• Remote dial-in (using telephone lines) through a modem attached to the EIA-232 service port using an ASCII or Serial Line Internet Protocol (SLIP) connection. See Figure 3-2. Modem Settings lists the modems that have been tested for use with the IBM 2212.

  SLIP is a method for sending IP packets, instead of ASCII data, across a serial link. (You cannot use SLIP to access the bootstrap menus.)

• Locally through a null-modem adapter and serial cables supplied with this product that are attached to the EIA-232 service port using an ASCII or SLIP connection. See Figure 3-1.

Table 3-1. User Console Attachment Options

Physical Attachment	Line Protocol	Access Protocol	Default IP Addresses
Service port + null modem Service port + external modem	Asynchronous ASCII	ASCII terminal emulation	Not applicable
	SLIP	Telnet	2212 = 10.1.1.2 Workstation = 10.1.1.3
Any IP network interface (not an option for the initial configuration of the IBM 2212)	IP	Telnet	No defaults

An ASCII connection requires an ASCII terminal or a workstation running an ASCII terminal emulator. SLIP requires that Transmission Control Protocol/Internet Protocol (TCP/IP) that supports SLIP be running on your workstation.

Once the IBM 2212 is up and running in the network, you can access the IBM 2212 by Telnetting from a network-connected workstation that is attached to any of the IBM 2212's IP-capable network interfaces. The network interface could be on a LAN adapter or WAN adapter since all of them support IP routing. The Telnet workstation could be locally or remotely connected.

SLIP Addresses

The default SLIP IP addresses are:

For the workstation:

10.1.1.3

For the IBM 2212:

10.1.1.2

For instructions about installing SLIP, refer to the documentation for your version of TCP/IP.

Service Port Default Settings

These are the default settings for the serial port:

Speed

19.2 Kbps

Parity

None

Data Bits

8

Stop Bits

1

You can configure the service port speed for the following bit rates; however, the speed must match the speed configured for the ASCII terminal. See Changing the Service Port Speed for instructions on setting the IBM 2212 service port speed.

Note:

For the initial configuration of the IBM 2212, you must use 19.2 Kbps. As part of the initial configuration, you can change the line speed of the service port. See Changing the Service Port Speed.

• 2400
• 9600
• 14 400
• 19 200
• 28 800
• 38 400
• 57 600
• 115 200

Modem Settings

The following modems have been tested for use with the IBM 2212:

• IBM 7852, Model 400
• Zoom/FaxModem 56Kx
• Atlas 33.6 External PC Data/Fax Modem.
• U.S. Robotics 56K Sportster Modem

You can use equivalent modems, with a minimum data transfer rate of 2400 line speed, with the IBM 2212.

For instructions on setting-up these and possibly other modems to operate with your IBM 2212, see the general information technical tips available at:
