5100-A2-GB21-00 November 1996
Selecting an I/O Base Address
To assist you in selecting an available I/O base address on your system, the
HotWire Diagnostics Utility provides a selection that scans your system to obtain
unused addresses. To compose the list, however, the utility must rely on the
integrity of your installed cards to report their base address usage correctly.
Procedure
To use this feature:
1. Enter Windows.
2. Double-click on the HotWire program icon to access the main menu. For a
complete description of this menu, refer to Chapter 3.
3. Select Recommend Base Address from
the Configuration menu to display a list
of unused base addresses.
If necessary, click on to scroll
the window.
4. Make a note of an available address.
5. Click on one of the following:
—Exit to close the window
and return to the main menu.
—Help to access screen help.
6. From the HotWire main menu,
select File, then select Exit to quit
the utility.
NOTE:
Typically, the utility will detect the card’s base address once it is installed.
Subsequently, when you select Recommend Base Address, the Available
Base Address window displays only that address.

Setting the I/O Base Address
I/O base addresses are areas of memory that your CPU uses to distinguish
between the various peripheral devices connected to your system when
transferring or receiving data. This card uses a single DIP switch bank (SW1), as
shown in the card illustration below, to assign the card’s base address. The
illustration shows the switch settings for an I/O base address of 380.
NOTE:
Each hardware device included in the system must have a different I/O base
address.

Procedure
To set the I/O base address switches:
1. Determine the appropriate I/O base address for the card. You may use the
utility feature for obtaining a list of unused addresses. See
Selecting an I/O
Base Address
on page 2-3.
2. Identify the switch settings for the address selected. Appendix D provides a
list of switch settings for possible addresses.
3. Set the switches to the desired address. A switch in the up or On position
represents a binary 1. A switch in the down or Off position represents a
binary 0.

5100-A2-GB21-00 November 1996
NOTE:
Switches 7 and 8 on SW1 are not used so they may be On or Off. The
example shows them On.
Make a note of the base address used so you can verify/set that address in the
HotWire Hardware Setup window after the HotWire software is installed.
Setting the IRQ Switches
IRQ (hardware interrupt request) is a signal used by your device to inform your
CPU when it wants to transfer or receive data. Use Switch Banks 2 and 3 (SW2
and SW3) to select an IRQ. You can use the following illustration to locate these
switches. The callouts show the switch settings when IRQ is set to 5.
NOTE:
The IRQ setting must not conflict with any other device in the PC.

"Procedure
To set the IRQ switches:
1. Determine the appropriate IRQ for the card. Using the previous table, you
may already know of an available IRQ. It not, refer to your PC documentation
for instructions on how to determine available IRQs. Typically, the available
IRQ settings are 5, 7, 10 and 11. It is common in systems to use the other
IRQs for system devices.
2. Identify the switch to be set on SW2 or SW3 for the selected IRQ using the
previous table (note that the table shows the setting if the IRQ is set to 5). A
switch in the On position selects the IRQ associated with that switch. All other
switches should be Off.
3. Set the switch.
Make a note of the IRQ setting used so you can verify/set the Interrupt No. in the
HotWire Hardware Setup window after the HotWire software is installed.

Inserting the Card
Procedure
To install your HotWire DSL card into your PC:
CAUTION:
This modem card is intended to be installed in UL Listed CSA Certified
equipment in the field by the user in the manufacturer’s defined
operator access area. Check the equipment operating/installation
instructions and/or equipment manufacturer to verify/confirm if your
equipment is suitable for user-installed application cards.
1. Turn Off the PC. Disconnect cables for the monitor and any powered
equipment to the PC. Then, lay the PC chassis on a flat surface.
2. After waiting at least one minute, remove the PC cover and touch the metal
PC frame to discharge any static electricity on your clothes or body.
CAUTION:
Plugging in and turning on the system at the wrong time could result in
an electrical shock to you or cause damage to your computer system’s
components.
3. Choose an unused 16-bit expansion slot
for the card.
4. Unscrew and remove the slot cover

5. Verify that the DIP switches on the HotWire
card are set to the proper settings.
6. Insert the card into the expansion slot:
— Pick up the card by the edges or the
top corners. Be careful not to touch
the pins on the bottom of the card.
— Align the connector on the bottom of
the card, directly over the slot. Place
one hand along the top edge of the
card, directly over the connector
area, and push down firmly but
gently until the connector is fully
seated.
— To ensure that the card is properly
seated, gently try to lift the card.
7. Secure the card to the chassis using a bracket screw.
8. Insert the 6-pin plug on the provided
cable into the network access jack
on the card. Connect the other end of
the cable to the network access point.
9. Plug in the power cable and
power on the PC, being careful not to
touch any internal boards or components,
and verify that the LEDs function as
follows (refer to Appendix A to locate
the LEDs):
— The SYS LED turns solid green.
Refer to the
Power-Up Self-Test
section following this procedure if
the SYS LED does not turn green.
— The CD LED blinks and then both the CD and LNK LEDs turn solid
green. This indicates that the card is communicating with the central
office unit, meaning your DSL link is operational. If the CD and LNK
LEDs do not function as stated, stop the installation process and
contact your customer service representative for assistance.
10. Turn the power Off again.
11. Replace and secure the cover to the PC.
12. Plug in the monitor and other peripheral devices you disconnected and power
on the PC.

Power-Up Self-Test
Whenever you turn on your system or after the card reset operation is selected in
the Diagnostics Utility, a power-up self-test is automatically performed on the
HotWire DSL card to ensure that the card is installed and functioning properly.
The self-test includes a basic hardware test and verification of card components.
The SYS (system) LED state identifies the following conditions by:
Turning solid green if the test is successful.
Turning Off if the test fails.
The LEDs are only visible when the PC cover is removed. To locate the SYS LED
on the card, refer to Appendix A for an illustration of the LEDs. If the test fails:
Recheck or change the IRQ setting.
Check the seating of the card.
Installing the Network Driver
After installing the card, you must install the network driver.
If you are using . . . Refer to . . .
