Technical Product Specification

Cooling Subsystem Intel® Server System SR1600UR TPS
24 Intel order number E45725-010 Revision 1.8
4. Cooling Subsystem
The cooling subsystem is composed of five 40x40x56-mm dual-rotor fans, two 40x40x28-mm
power supply fans, a CPU air duct, and a power supply/electronics bay isolation air baffle.
These components are used to provide the necessary cooling and airflow to the system.
A fan
on the processor heatsink is not necessary in this chassis.
In order to maintain the necessary airflow within the system, the air baffle, CPU air duct, PCI
riser assembly, and the top cover need to be properly installed.
Note: The Intel
®
Server System SR1600UR does not support redundant cooling. Should a fan
fail, the system should be powered down as soon as possible to replace the failed fan.
4.1 Five-fan Module
A fan assembly consisting of five 40x40x56-mm dual-rotor multi-speed fans provides the
primary airflow for the system.
Four of the dual-rotor fans provide the primary cooling for the
processors, memory, and second and third hard drive bays. The fifth dual-rotor fan provides the
primary cooling for the components in the full-height PCI zone.
Removal and insertion of the fans and the fan module is tool-less and provides for easy
installation and serviceability.
Fans are individually replaceable through a connection to the hot-
swap backplane.
Both the fan assembly and the individual fans within it are not hot-swappable.
The server must be turned off before any of the fans can be replaced.
Each dual-rotor fan has a 10-pin wire harness, which connects to the hot-swap backplane.
Each fan harness provides power and tachometer lines allowing the fans to be monitored
independently by the Intel
®
System Management Software.
