installation instructions.
Use the following procedure to install your IBM WAN Adapters.
1. Set the host computer system power switch to OFF and disconnect the
power cord.
2. Locate a free PCI expansion slot.
3. Insert and secure the board firmly into the expansion slot.
4. Replace the power cord and turn the host computer system ON.
Software Installation
Refer to the Quick Start Card that came with the CD ROM for detailed
instructions on loading the Software Driver.
PCI System Setup
Peripheral Component Interconnect (PCI) system architecture has a design
feature termed Plug and Play. This feature automatically detects, identifies and
configures the currently installed devices each time the system is booted.
Therefore, whenever a WAN Adapter is installed (or removed) in a PCI system,
the Adapter is recognized and configured immediately upon restart.

Connection Status Indicators 4
Connection Status Indicators
IBM PCI WAN 2 Port S91
Asshown inFigure 1below,the IBMPCIWAN2PortS91 hasthreestatuslights
(LEDs) on the end bracket. Two of these lights indicate the status of the ISDN
connection, and the third identifies the card during configuration.
Figure 1: Status Lights
D-channel Status
The D-channel controls the link to your ISDN
service provider.
Off ...........Theline is not active. Thecable may
not be connected.
Blinking...The line is active, but a link can’t be
established. This may be a symptom
of incorrect configuration.
Steady......The ISDN line is active and
operating normally.
B-channel Status
The B-channels are used for the link to the
remote ISDN device.
Off........... There is no connection.
Blinking... Attempting to connect to the remote
device.
Steady...... The connection is active and able to
transmit data.
Configuration Status
This status light illuminates during
configuration to indicate which card is being
configured. This is most useful when more than
one card is installed in the PC.
Consult the documentation provided with the
configuration software for information about
this status light.

5 Connection Status Indicators
IBM PCI WAN MultiPort T1/E1 S94 and
IBM PCI WAN MultiPort T1/E1 P92
The green LED adjacent to each port on the IBM PCI
WAN MultiPort T1/E1 S94 and the IBM PCI WAN
MultiPort T1/E1 P92 (see Figure 2 at right) provides a
convenient indication of the status of the connection on
that port.
Explanations for the different LED states can be found
in Table 1 below.
LED State Connection Status Remedy
Off The port is not loaded (the configuration
file describing protocol and interface
parameters has not been read by the
device driver on the PC).
Consult your networking software
for instructions on how to load a
configuration file andhowtostarta
connection.
Rapid Flash
(stays on for
1/2 second)
The connection has not been established.
Either the port is loading, OR there is no
response from the destination device,
OR the WAN Adapter is waiting for a
VHSI cable to be connected to the port.
Verify that the cable is properly
connected to the port. If the light
continues flashing after a few
minutes, verify that the destination
device is active.
Slow Flash
(stays on for
1 second)
The connection was interrupted
unexpectedly. The cable was unplugged
or damaged while a connection was
active.
Reconnect the cable.

VHSI Cable Construction Information
If you plan to construct your own VHSI cables, be sure to observe the guidelines
given below.
Wire Gauge, Grounding, and Pairing
• Use 28 AWG 7-strand wire with 0.020–0.028" insulation.
• The chassis must be grounded both bya drain wireand bythe braid;both must
be connected to the connector case and shell at each end of the cable. The
braid must be connected through its full circumference.
• Wires identified under the heading “Twisted Pairs” must be paired. If you do
not install twisted pairs correctly, the cable will not work.
Type of Connectors
The VHSI port accepts a high density 36-pin male cable connector. The types of
connector used on the interface-specific end of the cable are as follows:
Interface Connector
