FW 07.00.00/HAFM SW 08.06.00 McDATA Sphereon 4300 Fabric Switch Installation and Service Manual (620-000171-010, April 2005)

Repair Information
4-19
• 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 Tes ting).
• 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.
Perform Port Diagnostic Loopback Tests
Port diagnostics consist of internal and external loopback tests. The
tests are performed on any selected port at the SANpilot interface.
The tests are described as follows:
• 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.
Internal Loopback
Test
To perform an internal loopback at the SANpilot interface:
1. Notify the customer that a disruptive internal loopback test is to
be performed. Ensure the customer’s system administrator
quiesces Fibre Channel frame traffic through the port, and sets the
attached device offline.
