2. At the management server, open the SAN management
application (SANavigator or EFCM).
3. At the SAN management application physical map, right-click
the product icon representing the director to be tested, then select
Element Manager from the pop-up menu. The application opens.
4. Disconnect the fiber-optic jumper cable from the port to be tested.
If a port card will be tested, disconnect all fiber-optic jumper
cables.
ATTENTION! If name server zoning is implemented by port number, ensure
fiber-optic cables that are disconnected to perform the loopback test are
reconnected properly. A cable configuration change disrupts zone operation
and may incorrectly include or exclude a device from a zone.

— If the port to be tested is shortwave laser, insert a multimode
loopback plug into the port receptacle.

loopback plug into the port receptacle.
— If an entire port card will be tested, insert an appropriate
loopback plug in all port receptacles.
