System Cooling; Fan Board Assembly With Six Fans; Fan Board Assembly With Six Fans - Intel SRKA4 - Server Platform - 0 MB RAM Product Manual

System Cooling

The SRKA4 MP Server System uses up to six fans mounted in a fan board assembly in the middle
of the chassis between the E-Bay and peripheral device bays. The six fans are noted by "A" in
Figure 5.
The SRKA4 server cooling system supports either a non-redundant configuration or a redundant
configuration. A non-redundant configuration includes just three fans. If any one of these three
fans ceases to function normally, environmental conditions within the chassis may exceed the
environmental regulations in this guide and the chassis may not function normally. Three fans
support any system configuration but without fan redundancy.
Operating the server with a non-redundant cooling system is not recommended for systems
requiring high availability. To maintain SRKA4 MP Server System availability, Intel recommends
the use of all six fans to form a redundant cooling system. If one of six fans ceases to function
normally, the remaining five fans adequately cool the system. Using six fans supports any
configuration up to the maximum configuration. Six fans support a maximum set of components.
These components include four processors, 8 GB of SDRAM memory, five 10k hard drives, eight
PCI add-in boards, and at least two power supply modules.
Air flows in through the front bezel over the power subsystem bay, the peripheral bay, and the hard
drive bay. The air then passes through the fan board assembly and to the baseboard. Finally, the
air exhausts through the rear and left side of the chassis.
Individual fan status indicators are located on the fan board mounted in the fan board assembly.
Fan failure is also indicated by the general fault LED located at the front of the chassis.
WARNING
The total power requirement for the SRKA4 MP Server System exceeds
the 240 VA energy hazard limit that defines an operator-accessible area.
Only qualified service technicians should access the processor, memory,
power subsystem, and non hot-plug/hot-swap areas of the SKA4
baseboard.
CAUTION
The top cover must be on the system for proper cooling.
