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.
