The LEDs should be evenly spaced and be inside the edges of the ports to prevent confusion.

If the port can be split, the LED for each split port should also be placed above the port. This prevents the LEDs from being hidden by drooping cables.

Location - A port LED should be placed right above the port.

So a 40G port that can be split into 4 10G ports has 4 LEDs, one per split port. Ports that can be split should have 1 LED per split port.

Number of LEDs per port - Ports that cannot be split for example, 1G ports must have 1 LED per port.

Here are the requirements for these LEDs: Network Port LEDsĪ network port LED indicates the state of the link, such as link UP or Tx/Rx activity. This provides a network operator with a standard way to identify the state of a switch and its ports by looking at its front panel, irrespective of the hardware vendor or NOS.

This chapter provides a set of guidelines for how network port and status LEDs should appear on the front panel of a network switch. Network Switch Port LED and Status LED Guidelinesĭata centers today have a large number of network switches manufactured by different hardware vendors running network operating systems (NOS) from different providers.
