    摘要: A field unit has a connector with first and second interconnect apparatus coupled to connector. The field replaceable unit has test apparatus coupled to the first and second interconnect apparatus capable of testing connections through the connector to the first interconnect apparatus under control of signals on the second interconnect apparatus. The field replaceable unit is capable of being hot-plugged. In an embodiment, the second interconnect apparatus is of the JTAG type. Also claimed is a method of testing interconnect between the field replaceable unit and another unit of a system into which it has been hot-plugged.
