6 Chapter 2 Installation Guide
NOTE
If at all possible, plug all power cords from the PCI Expansion System
and your host computer into a shared power strip, preferably one that
has surge and noise suppression circuitry built into it.
Step Three: Recheck Installation
Check your installation before powering up the PCI Expansion System
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.
Step Four: Power Up
NOTE
The 400-watt and the 300-watt redundant power supplies are auto
switching, which means the power supply will automatically adjust to
the voltage required for the region you are in.
NOTE
For systems that have a 300W redundant power supplies; a red push
button is provided on the back of the enclosure to silence the audible
alarm in the event of a power supply failure.
You must apply power to the PCI Expansion System first and then
power up your host computer. This will allow the higher numbered PCI
buses in your hierarchy to be at a stable state at the time that 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 the attached devices.
If you have several PCI Expansion Systems in your configuration, you
should power up the most "downstream" expansion system first, then
each expansion system moving “upstream” and finally the host system
last.
There is an On/Off switch on the front panel as well as an LED indicator
to indicate power status. Verify that the green power indicator is ON.
