Description
If the indicator is steady green, it indicates that the fan module works
normally.
The indicator is off when the fan module is unregistered, powered
off, or has a hardware fault.
If the indicator is steady red, it indicates that the fan module fails.
The IP packets sent from PICs and 2x10G interfaces on an NPU converge at a convergence
module.
The NP processes the IP packets.
The TM module performs traffic management on the IP packets.
The Fabric Interface Chip (FIC) performs IP packet switching.
