Description: The fan's mesured speed in Tach units (RPM/120). Each Byte represents a fan. AC INI-Param: N/A
What is acSysFanTrayFansCurrentSpeed?
AC-SYSTEM-MIB::acSysFanTrayFansCurrentSpeed records the actual measured rotation speed for each fan in Tach units (RPM divided by 120), stored as individual bytes. You compare this against the configured speed to detect failing fans—if a fan's actual speed is much lower than configured, it may be struggling or failing. For example, if configured speed is 0x80 but current speed shows 0x40, the fan is spinning at only half its intended speed and likely needs replacement.
