Hot Swap FAN
The system has five hot swappable fan modules (six fans). The failed fan module can be easily removed or replaced without turning power off. Each fan module has a fan alarm LED and each fan is redundant in configuration. If one fan fails, its associated fan changes its rotating speed to high. Table
