Perform Port Diagnostic Loopback Tests - HP StorageWorks Edge Switch 2/12 Service Manual

Perform Port Diagnostic Loopback Tests

Port diagnostics consist of internal and external loopback tests. The tests are
performed on any selected port at the EWS interface. The tests are described as
follows:
Edge Switch 2/12 Service Manual
Operating Speed - Operating speed (Not Established, 1 Gbps,
or 2 Gbps).
Port WWN - Fibre Channel world wide name (WWN) for the port.
Block Configuration - User-configured state for the port (Blocked or
Unblocked).
Beaconing - User-specified for the port (On or Off).
FAN Configuration - User-configured state for fabric address notification
(FAN) configuration (Enabled or Disabled).
Operational State - Port state (Online, Offline, Not Installed, Inactive,
Invalid Attachment, Link Reset, No Light, Not Operational, Port Failure,
Segmented E_Port, or Testing).
Reason - A summary appears describing the reason if the port state is
Segmented E_Port, Invalid Attachment, or Inactive. For any other port
state, the reason is N/A.
Technology - Information specific to the installed optical transceiver,
including connector type, transceiver optics, data transmission distance,
optical media (cable type), and transmission speed.
Internal loopback test - An internal loopback test checks internal port,
serializer, and deserializer circuitry and checks for the presence of an optical
transceiver, but does not check fiber-optic components of the installed
transceiver. Operation of the attached device is disrupted during the test.
External loopback test - An external loopback test checks all port circuitry,
including fiber-optic components of the installed optical transceiver. To
perform the test, the attached device must be quiesced and disconnected from
the port, and a singlemode or multimode loopback plug must be inserted in
the port.
