Abstract

Disclosed is a way for users to map the physical adapter to the TCP/IP(Transmission Control Protocol/ Internet Protocol) interface of the adapter by reading a LCD (Liquid Crystal Display) Panel on the adapter.

LCD Panel On Adapter

It is difficult for Operating System users to quickly determine the exact physical location of a specific adapter given the Transmission Control Protocol/Internet Protocol (TCP/IP) interface. For example, if a user determines there is a link problem with an instance of his adapter, he can not physically map the adapter to the instance number, because the adapters may not physically lay in numerical order. Therefore, he must determine the adapter location through trial-and-error, or through a Program Control Interrupt (PCI) slot mapping.

To solve this problem a Liquid Crystal Display (LCD) will be mounted over each PCI slot, and will display the instance number of the adapter and any error codes that occurred on that adapter. The LCD display can also indicate the current state of the adapter.

A kernel application will talk to a LCD controller located on the system planer that will display the specific information to a small LCD display mounted over the adapter slot. The LCD display will display the IP interface number and any error codes on the LCD display. The application will poll the error report to determine if the device driver has reported a fatal error to the adapters. If a fatal error is determined the LCD will flash the fatal error code.
