Chapter 2
Installing Asanté MacCon Cards
This chapter provides step-by-step instructions for installing Asanté
MacCon Ethernet network interface cards and EtherTalk software.
To install an Asanté MacCon Ethernet card,you will perform the fol-
lowing operations:
❏
Prepare for the installation
❏
Install the MacCon card
❏
Connect the Macintosh to the network cable
❏
Terminate the cable where applicable
❏
Install the EtherTalk software
Preparing for the Installation
Before you open the anti-static bag containing the card, you must
prepare for the installation as described below.
Make sure you meet all the requirements and are aware of the safety
rules.
Checking the Requirements
Before you open the anti-static bag containing the Asanté MacCon
card, make sure you have the following:
❏
The required software:
Apple system software 6.0.8 or higher
A network operating system or a compatible system and appli-
cation software to run the network,provided byApple or a
third-party vendor.
❏
The EtherTalk Installer diskette provided byAsanté.

2-2 InstallingAsanté MacCon Cards
❏
The appropriateAsanté card and Ethernet hardware for your
cabling:
Refer to Appendix B for detailed Ethernet specifications.
Observing the Safety Rules
Do not remove the network interface card from its anti-static bag
until you are ready to insert it into the expansion slot. The interface
cards are sensitive to static electricity and must be handled very care-
fully.Improper handling or installation can result in damage to your
card and/or your Macintosh.
Any damage you may cause to the computer or card will not be cov-
ered by the limited warranty.
Observe the following safety precautions during the installation:
❏
Consult your network administrator about the card installa-
tion before connecting to the network..
❏
Turn off the Macintosh and all peripherals connected to it.
❏
If you need to lay a Macintosh flat on its face,use an anti-
static mat.
❏
When installing the MacCon+ SE or SE/30 card,be extremely
careful not to touch any part of the exposed circuitry.Some
circuit components retain a high voltage charge long after the
power is disconnected.

❏
Ground yourself by using an anti-static wrist strap.Attach it to
the chassis once you have opened the Macintosh,but before
handling the Asanté card or touching any component inside
the system.
❏
Handle the Asanté card by the edges and avoid touching the
connectors and chips.
❏
Keep theAsanté card in the anti-static bag until you are ready
to install it in the Macintosh.
The MacCon NuBus Card
If your Macintosh accepts NuBus expansion cards, you can use the
MacCon NuBus network interface card to connect the Macintosh to
an Ethernet network.
You install a MacCon NuBus card into an unused Nubus expansion
slot on the motherboard.
Refer to your computer’s User Guide for illustrated instructions on
how to open your Macintosh computer.

∆ Note: If you are using
Thick
Ethernet (10Base5) cabling
and your network does not have 10Base5-compliant
Ethernet transceivers,you may need to force the card to
select theAUI port by setting the JP1 jumper ON as
shown in Figure 2-1.

1 Power down the Macintosh. Disconnect and remove the
power cable.
2 Open the Macintosh.
3 Remove the access port cover. Make sure you are ground-
ed: check that your anti-static wrist strap is properly at-
tached to your wrist and to the Macintosh chassis.
4 Plug the MacCon card into the NuBus expansion slot on
the motherboard:
— With the card’s Ethernet connectors facing the expan-
sion slot access port, carefully line up the card’s edge
connector with the expansion slot (see Figure 2-3).

ends.
With a Centris 610
If you are installing a MacCon NuBus card in an Apple
Centris 610, you need to use the Apple Centris 610 NuBus
Adapter, which is not included with the MacCon NuBus card.
The Apple Centris NuBus Adapter part number is M1402LL/A.
— Slide the MacCon NuBus card into the Centris 610 Nu-
Bus Adapter.

Installing the MacCon 610 Card
If you have a Macintosh Centris 610,you can use a MacCon 610 card
to connect to the Ethernet. Each card consists of two parts:
❏
The larger
controller
card,which plugs into the expansion
slot in the Macintosh.
❏
The smaller
daughter
card,which is mounted on the rear
access port to enable a connection to the Ethernet cable.
You connect the two cards before installing them.
To install the MacCon3 610,MacCon+ 610E,or MacCon+ 610ET
card in a Macintosh Centris 610,perform the following steps:
1 Set jumpers if needed (see the next two Notes and

2 Attach the daughter card to the controller card:
— Remove the two screws from the bracket on the smaller
daughter card.
— Hold the daughter card in your right hand so that its
components face down and the interface ports are on
the right. Hold the larger controller card in your left
hand so that you’re looking at the components.
— Connect the daughter card to the controller card at the
upper right corner of the controller card.
Caution
Handle theAsanté cards carefully so they remain plugged to-
gether.Be careful not to bend or twist the cards,especially

If you have a Macintosh LC,LCII,or Color Classic computer,use the
MacCon LCIII or MacCon-i LC card to connect the Macintosh to the
Ethernet.
Caution
Only the LC and LCII computers can accept FPUs on the LC card. If
your Macintosh already has a math co-processor (or FPU), do not
install the Asanté math co-processor option with the card.
Refer to your Macintosh User’s Guide for illustrated instructions for
opening your computer.
∆
Note: LCIII card
—You can disable link integrity on the Mac-
Con LCIII card by setting the JP2 jumper as indicated in Figure
