Recheck the Installation
Check your connection and installation before powering up the OSS 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.
2.10 Applying Power Correctly
You must apply power to the OSS expansion chassis
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.
First, turn on the power supply switch. Next, turn the power switch to ON position located on the front panel of the expansion unit. A green
LED indicator should light up when the switch is in the ON position, see picture below.
2.10.1 Shutting down the unit
When shutting your system down, it is recommended that you first shut down the computer correctly, and then power down the OSS
expansion chassis to avoid 'computer lock-up' and potential data loss.
STOP
DO NOT TURN ON THE OSS EXPANSION CHASSIS UNTIL YOU HAVE SHUT DOWN YOUR COMPUTER COMPLETELY! It can
cause a system lockup and loss of any unsaved data.
