Number of LEDs per unit - Each unit should have only 1 LED. Each component that has an LED is known as a unit below. Locator LEDs are also found on the front panel of a switch. Typical LEDs on the front panel are for PSUs (power supply units), fans and system. The status LEDs provide a visual indication on what is physically wrong with the network switch. In other words, a slow blinking amber LED is amber for 500 ms and then off for 500ms.Ī set of status LEDs are typically located on one side of a network switch. Slow blinking amber indicates a blink rate of 500ms, with a 50% on/off duty cycle. Blinking amber implies a blink rate of 33ms.Both try to draw attention of the network operator towards the port, thus they are signaled the same way. Fault can also be considered a form of beaconing or vice versa.The administrator can beacon that port from a remote location so the network operator has visual indication for that port. Beaconing provides a way for a network operator to identify a particular link.Physical Link Up/Down displays layer 2 link status.If the 10G port is running at 1G speed then its running at a lower speed. For a 10G port, if the port speed is 10G, then it is running at its maximum speed. Max Speed indicates the maximum speed at which the port can be run.Signaling - The table below indicates the information that can be conveyed via port LEDs and how it should be done.These colors are commonly found on network port LEDs and should be easy to implement on future switches. Hence, green and amber colors must be used on the LED to differentiate between good and bad states. The focus should be on giving a network operator a simple set of indications that provide the operator with basic information about the port.
