Specifications

fantool
The fantool tests the fans in the system, sets, and reports the fan speeds and the fan tray eld replaceable unit (FRU) registers. The
fantool also reports the airow direction of the fans. The psutool command controls the PSU fans.
NOTE: This tool is not available for the N1108EP-ON switch.
Tests
The fantool tests the fans by setting them to dierent speeds and then verifying the congured fan speeds.
Registers and values pass as hexadecimal values with or without the preceding 0x. Fans display from 1 to Max System Fans.
