Each EISA option slot is rated at 4.5A per slot, however average current
consumption for all slots used should not exceed 3A per slot. Most EISA
option cards draw 2A. If you install a card drawing more than 2A, install it in
a lower numbered slot (such as 1 or 2) to ensure adequate cooling.

SIMM Installation
There are four SIMM sockets organized in two banks on the
main system board. You can install 36-bit, tin-plated,
page mode, single or double-sided SIMMs with a capacity of
lMB,
2MB, 4MB,
16ME or 32ME running at 70ns or
or
SME
running at
7Ons
or a capacity of
801~.
Check the following
guidelines to ensure that you choose the correct type of
SIMMs and install them properly:
u
Use only 36-bit, tin-plated, fast-page mode, single- or
double-sided SIMMs that operate at an access speed of 70
or 80 nanoseconds (ns). You can install lME,
or
SME Sons
u
Fill each bank with two SIMMs of the same size.
u
Install SIMMs in Bank 0 first (sockets JO550 and J0551).
SIMMs and 16ME or
32ME 7Ons
Then use Bank 1 (sockets JO650 and J0651).
The table below lists some sample memory configurations.
You can install SIMMs in many different configurations than
those listed in the table.

Installation/Support Tips
System Power Requirements
The power cord must be rated for at least 125% of the current
rating of the AC voltage system and must be less than
14.76 feet (4.5 meters) long to comply with the system’s
safety requirements. Do not use or attempt to modify the
supplied AC power cord if it is not the type required for use
in your region.
To avoid permanent damage to the computer, be sure the
voltage selector switch is set to the correct input line voltage
before you turn on the power. The computer is shipped with
the voltage selector switch set to 115 VAC, which is
appropriate for line source voltages between 100 and 120
VAC. If the line source voltage in your location is between
I
200 and 240 VAC, make sure you set the switch to 230 VAC.
Keyboard and Monitor
Even if you intend to use this system as a network file server,
you need to connect a monitor and a keyboard to complete
the installation. You may remove them once the installation
is complete.
Mouse and Keyboard
When connecting the mouse and keyboard, be careful to plug
I
them into the proper ports. Although they are physically
identical, they are not interchangeable, and damage may
occur to the ports or the main system board.
Option Cards
The order in which you install option cards depends on the
type of cards you have. If you install only ISA option cards
that do not have their own configuration files, install them
before you connect your peripheral devices. Follow the
instructions in your ISA card manual to set the card’s
switches or jumpers for your system.
Also install any EISA cards you plan to use before you
connect peripheral devices so your EISA Configuration
utility can automatically detect the cards and configure them
correctly.
If you install ISA cards that came with their own
configuration (CFG) files, install them after you have
connected the necessary peripheral devices and run the
computer’s EISA Configuration utility. This allows you to
I
add the CFG file information to your configuration so the
program can give you the card’s correct jumper and switch
settings. Then you can set the switches and jumpers and
install the card. See the documentation that came with your
card(s) for more information.

SETUP Program
Use the SETUP program in your system’s BIOS ROM to
configure your computer only if you installed only ISA
option cards that did not come with CFG files or you do not
have a diskette drive or you have disabled the diskette drive.
Run the EISA Configuration utility to configure the system in
all other cases.
