Technical rules for system fans

Your server supports two types of fans:

  • Single rotor 9238 hot-swap fans

  • Dual rotor 9256 hot-swap fans

Fan slot locations
Table 1. Fan and PCIe slot locations
1 PCIe slot 1-44 Fan slot 3
2 PCIe slot 5-95 Fan slot 2
3 Fan slot 46 Fan slot 1
Attention
Either type of hot-swap fan in fan slot 4 would spin at 10% duty when in standby.
