MAGMA
Chapter 2 Installation 5
Recheck the Installation
Check your installation before powering up the MAGMA expansion
chassis for the first time. Although the power supply has an over voltage
protection device built into it, it may not "trip" in time to fully protect a
device that has been improperly connected, or whose power cable has
been damaged.
CAUTION
When using your MAGMA expansion chassis outside of the United
States, make sure that you have correctly identified the voltage of
your power source and that you are connected to it correctly.
Remember, the power adapter supplied with your Expansion System
will automatically adjust to convert the source power into 12-Volt DC
current. Therefore, if you are using a power source other than 110V
US Standard, you will need a different power cord to connect your
source power to the power adapter, or a power cord adapter so you
can plug the 110V US Standard power cord directly into your source
power.
Applying Power Correctly
Starting Up:
You must apply power to the MAGMA expansion chassis BEFORE you
power up your computer. This will allow the higher numbered PCI buses
in the PCI bus hierarchy to be at a stable state when the host system
issues its master power-on bus reset. In systems that perform automatic
PCI bus configuration, this will allow the configuration code to recognize
the PCI bus hierarchy and any attached devices.
There is an On/Off switch on the expansion chassis, as well as an LED
indicator to indicate power status. Consult the Expansion Chassis User
Guide for the location of the On/Off switch. Verify that the LED power
indicator is ON.
STOP
DO NOT TURN ON THE MAGMA EXPANSION CHASSIS UNTIL
YOU HAVE SHUT DOWN YOUR HOST COMPUTER
COMPLETELY! It can cause a system lockup and loss of any
unsaved data.
