First Claim
Patent Images
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; and
determining a status of at least one of the plurality of information handling systems with the PoE compliant devices when the at least one of the plurality of information handling systems looses main power.

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.
