Hardware Installation
Your PC or PS/2 must have a 5250 twinax card installed to use AS/400
PC Support.
Connect your PC or PS/2 to the 5394 controller or AS/400 with a
standard twinaxial cable. This cable must have appropriate connectors
on both ends. You can use IBM parts or equivalents. Male connectors
are IBM part #7362229; female connectors are IBM part #7362230.
This section presents generic procedures for installing a 5250 twinax
card. Read all of these steps before you begin. Also read the instructions
or precautions in the documentation that came with your PC or PS/2 and
the installation instructions for your particular 5250 twinax card.
Always unplug your PC or PS/2 anytime you install hardware in it. It is
important to unplug the machine, rather than just turn it off, because
some components have voltages present even when the power is off.
Another good precaution to prevent static damage is to ground yourself
by touching a metal part of your system before you handle the card. Also
be careful not to drop or otherwise damage the card.
1. The 5250 twinax card has groups of switches or jumpers that
establish certain electrical connections depending on their settings.
They are preset to addresses that probably will fit your needs. See
the card's instructions for information on reading and changing the
settings.
2. Make sure the new card does not use the same addresses as
another card already installed.
3. Make any additional modifications called for in the card's instructions.
4. Turn off your PC or PS/2 and unplug it. Carefully open it. Avoid
touching the power supply while working inside.
5. Most PC's and PS/2's have several empty slots located toward the
rear of the system unit. You usually can install a card in any empty
slot that is the correct size. Make sure the slot is free from
obstructions and the metal contacts in the slot and along the edge of
the card are clean. Avoid touching these contacts, as you might
leave harmful deposits on them.
6. Hold the card by its corners and slide it into the slot as far as it will
go. Make sure it is straight and securely in place. In many PC's and
PS/2's, you also must insert a screw to hold the card in place.
