1. A method for performing management and diagnoses of information handling systems having power over Ethernet (PoE) compliant devices, said method comprising the steps of:
- communicating with a plurality of PoE compliant devices, each of the plurality of PoE compliant devices being coupled to a one of a plurality of information handling systems;
determining a status of at least one of the plurality of information handling systems with the PoE compliant devices, wherein the step of determining is performed after the at least one of the plurality of information handling systems loses main power; and
remotely controlling the at least one of the plurality of information handling systems with the PoE compliant devices, wherein the step of remotely controlling is performed when the at least one of the plurality of information handling systems loses main power, wherein remotely controlling includes;
in response to a failed communication caused by the at least one of the plurality of information handling systems losing main power,keeping out of band management operational by routing one or more management modules to separate PoE compliant devices when the at least one of the plurality of information handling systems loses main power, wherein the one or more management modules manage the operation of one or more of the plurality of information handling systems;
detecting whether a graceful shutdown occurred at the at least one of the plurality of information handling systems, anddetermining whether to perform a disconnect of the at least one of the plurality of information handling systems from a network.

Abstract
A power over Ethernet (PoE) compliant device may be able to keep alive just enough of a management controller and/or target to respond to requests and tell a host (initiator) why it may be unable to respond to a data transfer request in a desired fashion due to a power failure. Thus only a small portion of an information handling system management capabilities need stay alive for reporting the operational condition of the overall information handling system during a power outage.

17. A system for performing management and diagnoses of information handling systems having power over Ethernet (PoE) compliant devices, said system comprising:
-
a plurality of information handling systems, each of the plurality of information handling systems having a PoE compliant device, wherein each of the PoE compliant devices are communicating with other ones of the PoE compliant devices; and wherein at least one of the plurality of information handling systems, after any of the other ones of the plurality of information handling systems loses main power, performs management and diagnoses of the other ones of the plurality of information handling systems, and remotely controls the other ones of the plurality of information handling systems with PoE compliant devices, wherein remotely controlling includes; in response to a failed communication caused by the at least one of the plurality of information handling systems losing main power, keeping out of band management operational by routing one or more management modules to separate PoE compliant devices when the at least one of the plurality of information handling systems loses main power, wherein the one or more management modules manage the operation of one or more of the plurality of information handling systems; detecting whether a graceful shutdown occurred at the at least one of the plurality of information handling systems, and determining whether to perform a disconnect of the other ones of the plurality of information handling systems from a network. - View Dependent Claims (18, 19, 20, 21, 24, 25)
