command to shut down
all controllers to which the loop is connected.
3. Disconnect the AT-FCX module from the Fibre Channel cabling. If you are
using optical cables, remove the associated SFPs from the input and
output ports of the AT-FCX module.
4. Using the thumb and index finger of both hands, press the levers on the
cam mechanism on the module to release it.
5.
