Note: After a port is reconfigured, the port LED can remain amber for up to 30 seconds as STP checks the network topology for possible loops. Port is blocked by Spanning Tree Protocol (STP) and is not forwarding data. Error frames can affect connectivity, and errors such as excessive collisions, cyclic redundancy check (CRC) errors, and alignment and jabber errors are monitored for a link-fault indication. This status is availablethrough the device manager Front Panel view. No link, or port was administratively shut down. The internal power supply in a switch has failed, and the RPS is providing power to the switch (redundancy has been allocated to this device). If it does not, the RPS fan could have failed. Press the Standby/Active button on the RPS, and the LED should turn green. The RPS is in standby mode or in a fault condition. RPS is connected but is unavailable because it is providing power to another device (redundancy has been allocated to a neighboring device).
RPS is connected and ready to provide back-up power, if required. System is receiving power but is not functioning properly.Ġ2 – Redundant Power System (RPS) LED RPS Status Only the Catalyst 2960 PoE switches have a PoE LED.

The switch software configuration guide describes how to use the CLI to configure and to monitor individual switches and switch clusters. below shows the switch LEDs and the Mode button that you use to select one of the port modes.Īll LEDs are visible through the GUI management applications-Network Assistant for multiple switches and the device manager for a single switch. You can use the switch LEDs to monitor switch activity and its performance.
Through information sharing and resource allocation, switches save businesses money and increase employee productivity. A switch serves as a controller, enabling networked devices to talk to each other efficiently. Most business networks today use switches to connect computers, printers and servers within a building or campus.
