Abstract

A system and method for switch management includes a switch including a plurality of switch modules, and a status display panel. The plurality of switch modules includes one or more power supply modules for providing power to the switch, one or more cooling modules for cooling the switch, and one or more switching modules. The switch is configured to detect the plurality of switch modules, interrogate the detected switch modules, hierarchically organize status information based on information associated with the interrogated switch modules, and display the organized status information on the status display panel. The status information is displayed on the status display panel using an interactive status display system. In some examples, the switch further includes a plurality of status indicators, and the switch is further configured to temporarily activate the status indicators in response to active use of the status display system.

detect addition or removal of modules during operation of the switch; and

update the status information based on information associated with the added or removed modules.

10. The switch of claim 1 wherein the first one of the modules is further configured to display informational messages on the touchscreen status display panel based on the status information.

11. The switch of claim 1 wherein the first one of the modules is further configured to allow configuration of the switch using the touchscreen status display panel.

12. The switch of claim 11 wherein the switch is configured to apply a security policy to prevent undesirable configuration of the switch.

13. The switch of claim 1 wherein the first one of the modules is further configured to:

in response to detecting insufficient cooling in the switch, display a first status message indicating insufficient cooling using one or more visual indicators;

in response to detecting insufficient power in the switch, display a second status message indicating insufficient power using one or more visual indicators;

in response to detecting a loss of communication with one or more modules of the plurality of modules in the switch, display a third status message using one or more visual indicators, the third status message indicating a loss of communication with the one or more modules of the plurality of modules; and

in response to detecting a failure in one of the plurality of modules, display a fourth status message indicating the failure using one or more visual indicators, the fourth status message including a failure in a port or network link.

14. The switch of claim 1, wherein active use corresponds to one or more of the group consisting of activation of a line card user interface element, activation of a RPM user interface element, and activation of a SFM user interface element.

15. The switch of claim 1, wherein active use corresponds to one or more of a group consisting of activation of a line card user interface element, activation of a RPM user interface element, activation of a SFM user interface element, activation of a Fan Tray user interface element, activation of a switch user interface element, activation of a Power user interface element, activation of a Chassis user interface element, and activation of a port user interface element;
