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 front panel,
as well as an LED indicator to indicate power
status. Verify that the green power indicator is
ON.
