Method and Apparatus for Relating Device Name to Physical Location of Device on a Network

摘要

A method and apparatus for relating a device name to a physical location of a device ( 202 ) on a network is provided. The network may be a serial loop network, for example a Fibre Channel Arbitrated Loop network. The network includes a plurality of devices ( 202 ) on or connected to the network ( 201 ) and a control device ( 205 ) with control over at least one of the devices ( 202 ). Each device ( 202 ) has a check output ( 204 ) independent of the network ( 201 ) with connection means ( 206 ) to a control device ( 205 ). The method includes the step of sending a device name from the check output ( 204 ) of a device ( 202 ) to the control device ( 205 ). The check output ( 204 ) of a device ( 202 ) is also connected to an external indication means for indicating the failure of the device ( 202 ).
