Check your 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.
You must apply power to the expansion chassis BEFORE you power up your computer. This will allow the higher numbered buses in the bus
hierarchy to be at a stable state when the host computer issues its master power-on bus reset.
Each power supply has an individual power switch at the rear as well as LEDs to indicate its power status. Ensure that the power switch next to
the power cord is flipped ON the “|” symbol. This enables the device to turn ON once it is activated through the main POWER SWITCH.
The LED on the top should turn on when the power cord is connected to the device from the outlet. In this case the AC POWER LED would turn
green. The LED below that is for DC power and should be red until the entire chassis is powered through the main switch or through the host
computer for remote power.
After first turning on each of the individual power switches in the back of the chassis, the entire system can then be turned on.
IMPORTANT
A power supply unit (PSU) should be switched off before removal and upon insertion of its replacement. After replacing a
PSU, be sure to secure the new one in place with its snap-in mechanism for better grounding and noise immunity.
