Follow the instructions in this section to install a fan module.

About this task

S017
moving parts
CAUTION
Hazardous moving fan blades nearby. Keep fingers and other body parts away.
S033
240VA shock hazard
CAUTION

Hazardous energy present. Voltages with hazardous energy might cause heating when shorted with metal, which might result in spattered metal, burns, or both.

Attention
  • Read Installation Guidelines and Safety inspection checklist to ensure that you work safely.

  • Prevent exposure to static electricity, which might lead to system halt and loss of data, by keeping static-sensitive components in their static-protective packages until installation, and handling these devices with an electrostatic-discharge wrist strap or other grounding system.

Note

Technical rules for system fans

Fans must be installed in a specific order based on the configuration of the server.

ThinkSystem ST650 V3 supports two types of fans:
  • Single rotor 9238 hot-swap fans

  • Dual rotor 9256 hot-swap fans

Figure 1. Fan slot locations
Fan slot locations
Table 1. Locations of PCIe slots and fan slots
1 PCIe slot 1-44 Fan slot 2
2 PCIe slot 5-95 Fan slot 3
3 Fan slot 16 Fan slot 4
Note
  • Single-rotor hot-swap fans cannot be mixed with dual-rotor hot-swap fans.

  • When the system is powered off but still plugged in to AC power, the fan in slot 4 may continue to spin at a much lower speed. This is the system design to provide proper cooling.
