Chapter 3. Accessing the 2216
This chapter explains how to access and manage the IBM 2216’s operational and
configuration software.
The network administrator or the IBM Support Center can access the IBM 2216
locally or remotely for configuration or diagnostics. The following sections describe
accessing the IBM 2216, configuration tools, and monitoring tools.
Access Methods
The IBM 2216 must be configured as part of the installation process. It needs
either an IP address or configuration for LAN emulation. Therefore, you have to
access it in one of the following ways:
¹
Through the PCMCIA modem or through a modem attached to the EIA 232
service port. These are the forms of remote connection, which rely on the
telephone lines.
¹
Through a null modem cable attached to the EIA 232 service port. This is
known as local connection.
You can set up both a local and a remote connection to the IBM 2216. However,
only one port can be active at any given time. If a workstation is connected locally
to the serial port and a call comes in over the PCMCIA modem, priority is given to
the call. After the call, the workstation being used to configure will have to log back
into the IBM 2216.
With local or remote connection, you can use a teletypewriter (TTY) connection.
TTY requires communications software. The preferred method is to use Serial Line
Internet Protocol (SLIP) over the local or remote connection. If you use SLIP, you
must have Transmission Control Protocol/Internet Protocol (TCP/IP) running on
your workstation.
Alternatively, you can use the Xmodem protocol and ProComm or other
communication software for file transfers.
Figures 3-1 and 3-2 illustrate a remote connection using the PCMCIA modem and a
local connection using a null modem.
Note: Post-installation configuration changes can be done using the Configuration
Program.
