Abstract: Methods and systems for implementing such methods for providing server diagnostic and system management information may include, but are not limited to: receiving a network fault status request input; illuminating one or more server node fault indicators for one or more degraded server nodes having one or more faults; receiving a server node fault status request input for a degraded server node having one or more faults; and displaying one or more diagnostic service notifications for one or more faults of the degraded server node. Display of diagnostic service notifications may allow for completion of various service operations associated with service notifications once information specific to a fault is presented. Such service operations may include placing a system in standby mode, transferring workloads to other systems, initiating a firmware update, placing the system in a mode that allows for physical maintenance, or ordering parts associated with one or more faults.
