Installation

Summary of Installation Steps

Installation of your Allied Telesyn network adapter card is

simple and quick. Generally, the installation of one network

adapter card with common software on PS/2 MCA bus or

compatible workstations is mostly automated. This chapter also

gives procedures for more complex installations.

The following list of steps for the simplified Allied Telesyn

network adapter card hardware/software installation is

explained in greater detail later in the chapter.

1. Installing the adapter card in an MCA slot:

Physically install the card in the computer’s card cage.

2. Installing option files:

These are Allied Telesyn files called “option” files by your

MCA-bus installation software, which installs them.

3. Configuring the adapter card:

This process is done by your MCA-bus installation

software, automatically or manually.

4. Saving configuration to the system partition:

This creates a backup of your system configuration in your

computer’s system partition.

OS/Environment-Specific Installation Information

Accurate and current network hardware and software

installation information changes with every network software

package, protocol stack or operating system. To respond quickly

and accurately to these changes, we have included the latest

installation information in a series of applications and OS specific

readme files on the Allied Telesyn CardAssistant diskette.

The file

\READ.ME

, on the CardAssistant diskette, contains a

guide to current readme files on that diskette, and is

recommended reading for the installer.

Installing the adapter card in an MCA slot

Refer to the computer’s manual for information on installing

card-cage accessories.

High voltages inside the computer present a safety

hazard. Make sure the power is OFF before

removing the cover.

This LAN adapter card is for use only with IBM

PS/2 or compatible UL listed personal computers

that have installation instructions detailing

installation of card-cage accessories. Installation

should be performed with precautions to prevent

damage to static-sensitive components.

Warning

tion

Installation

1. Make sure the computer’s power is turned OFF.

2. Pick the card slot you wish to use. Follow the

manufacturer’s instructions for adding a card.

TIP:

When installing the AT-1720FT temporarily remove the shields from

the ﬁber-optics cable connectors to give the connectors more clearance.

Do not turn ON your computer.

Installing option files

To install the Allied Telesyn option files on your computer’s hard

disk, this procedure uses the computer manufacturer’s special

“option copy” software and procedures. Typically, the computer

manufacturer will refer to the Allied Telesyn files as “option”

files, which are on the “option disk,” the Allied Telesyn

CardAssistant diskette.

1. To copy the option diskette, verify that all floppy disk

drives are empty. Turn the computer ON. In a few seconds,

one of two things happens. Either:

a. The Configuration Error screen with automatic

configuration prompt appears, because the computer

senses that its hardware has changed since the last

time it was turned ON. In this case, go straight to

Step 2.

Or:

b. The screen displays only a RAM-OK count and an

error number, and stops. In this case, turn the machine

OFF, insert the computer manufacturer’s reference

diskette into drive A:, turn the machine ON and go to

Step 2 when you see the automatic configuration

prompt.

AT-1720

2. At the “

Automatically configure the system? (Y/N)

”

prompt, answer N for no, and the Main Menu will appear.

Do not answer Y here, or you will have to reset your

computer to get back to this point.

3. Select the “

Copy an option diskette

” option, and follow

the procedure to completion.

4. Remove the Allied Telesyn diskette from the floppy drive.

Configuring the adapter card (auto-configure)

1. Verify that all floppy drives are empty if you followed Step

1a on page 7. If you followed Step 1b in the previous step,

place the computer manufacturer’s reference diskette in

drive A:.

2. At your computer’s keyboard, hold down the (control)

and keys, and press the (delete) key. This will

reset your computer. The first screen you see will be the

Configuration Error screen of the configuration installation

step.

3. This time, when asked “

Automatically configure the

system? (Y/N)

” answer Y for yes. A screen message

informs you when the configuration process is completed.

4. After you have completed configuring your system for the

adapter card, verify that your floppy drives are empty, and

re-boot your computer.

Configuring the adapter card (manual configure)

1. Boot your computer as in “Installing option files” Steps 1a

or 1b on page 7.

2. In the Main Menu, select the “

Set Configuration

” menu.

3. In the “

Set Configuration

” menu, select “
