Intel SR870BN4 - Server Platform - 0 MB RAM Product Manual page 33

A series pair of 120x38 mm system fans cools the processors and part of the I/O subsystem. The
rest of the processor/memory and I/O subsystem components, hard drives and power supplies are
cooled by a series pair of 120x25 mm system fans along with the power supply fans. Hot-swap
system fans drop into the fan bay and interface with connectors on the I/O board.
The fan bay also contains the individual fan status indicators that can be seen when the back top
chassis cover is open. A system fan failure is indicated by two LEDs, the LED on the
corresponding fan (A in Figure 12), and the Cooling Fault LED on the front panel (B in Figure 12).
