Intel® Server D50TNP Family Integration and Service Guide
7.18 System Fan Replacement
Required Tools and Supplies:
•
Anti-static wrist strap and conductive foam pad (recommended)
The Intel® Server System D50TNP family supports two system fan configurations as shown in the following
figures – one for liquid-cooled configurations and one for air-cooled configurations.
Figure 266. System Fan Configuration – Liquid-Cooled System
Figure 267. System Fan Configuration – Air-Cooled System
The system is designed to support fan redundancy. Should a single fan rotor fail, system management will
engage various system thermal controls to maintain system thermals below maximum limits. Depending on
the system configuration, the system fans are designed to be hot swappable.
In air-cooled configurations, the two outer 80 mm system fans are hot swappable.
In liquid-cooled and air-cooled system configurations, three 60 mm system fans share the same assembly
housing as a power supply module. The power supply module must be removed from the fan assembly
before removing the assembly housing from the chassis. Using hot swap for these system fans can only be
supported when the system is configured to support 2 + 1 power supply redundancy. Attempting to hot
swap one of these fans with power redundancy lost will cause the entire system to shut down, unless the
failed fan is in the same assembly as a failed power supply.
