Supply and the right power Switch controls the right Power Supply. Each Power 
switch is a rocker switch (press the right side (labeled 1) to turn it ON, press the 
left side (labeled 0) to turn it OFF). 

When you press a Power switch and turn it ON (and its associated Power Cable is 
connected to an active AC outlet and its associated Power Supply is installed), 
there is a two-second delay before the fans start and the Power Good LED on the 
front of the chassis lights. The Power Good light indicates that the Switch logic is 
receiving power within the proper voltage range. Refer to 

 for more information.

The Test Mode Switch on the front panel is for use only under the direction of 
QLogic Customer Support or your authorized maintenance provider. This switch is 
a rotary switch and must be in the position shown in 

 for normal opera-

tion. Note that the small arrow on the end of the shaft is straight UP.
