J4200 Array Fan Modules; Figure 1-17 J4200 Array Fans - Sun Microsystems J4200 System Overview Manual

J4200 Array Fan Modules

The fans circulate air inside the tray by pulling it through the vents on the front of
the assembly and pushing it out of the vents on the back of each fan.
Each J4200 array contains two hot-swappable fans for redundant cooling. Fan
Module 0 is on the left and Fan Module 1 is on the right. If one fails, the remaining
fan continues to provide sufficient cooling to operate the array. The remaining fan
runs at a higher speed until the failed fan is replaced. Replace a failed fan as soon as
possible.
