When a fault is reported, it can be caused by anycomponent of the data path. To identify the location of the fault, checkthe Link Status and Activity LEDs on the array controller and the server.Check the cable path for kinks, crimping, or other issues. For detailedLED information, see the user documents for the components.Removing the failed transceiver1. Disconnect the fiber-optic cable.2.
