System And Method For Performing Light Path Diagnostics Using RFID

For Reliability, Availability, and Serviceability (RAS) diagnostics for systems, some organizations use a light path technology for diagnosing and directing users to system failures. This process is to illuminate a light-emitting diode (LED) on the external system chassis to identify a system which needs attention. Then, the system user removes the hardware and uses a second set of light path indicators to understand which components have failed.

The problem that arises with this type of serviceability is that the server needs to be removed from service to further diagnose the issue. In some cases, the server may continue to run even with a failed component until a replacement is available.

There are also technologies that are known current arts which use an LCD panel or other user readable form to identify some failure status information once the user has been alerted that the system component has failed. These methods may indicate, for example, that dual in-line memory module 3 (DIMM3) has failed, but it does not provide a view of the physical layout of the system to DIMM3 or what type of DIMM needs to be replaced.

Organizations also use management infrastructures to help in this alert and identification process. However, the user must log in to the management system and go to the failure to understand the fault, and then physically locate the system using location LEDs. This process becomes cumbersome when a large number of systems are involved (e.g., when an administrator is attempting to locate more than one resource is attempting in an infrastructure).

Also, if the networking device has failed, then the server cannot transmit the failure information to the management server. The server provides an external light path indication of the failing component and the user physically locates the server to further diagnose the issue.

There may also be security concerns with having systems data transmitted through infrastructure networks. In addition, compute systems are sometimes isolated from external network systems, thus limiting the usefulness of call home, call back, or interrupt driven service functions.

The disclosed invention incorporates the use of only short-range wireless and/or passive wireless technology, requiring the physical locality to gather system diagnostic information and improving the security of the fault data.

This invention uses wireless communication, such as a Radio-frequency Identification (RFID) tag, to provide the same light path function as the current light-path schema. However, instead of a user having to physically interact with the system, an RFID scanner is used to communicate with the internal structures of the system. The scanner shows an isometric of the system being scanned and provides the internal light path
