Port Technology dialog box
The dialog box describes:
• Port Number - Product port number.
•
Connector type -
Type of port connector ( LC , Unknown , or Internal
Port ).
• Transceiver - Type of port transceiver ( Shortwave Laser , Longwave
Laser , Long Distance Laser , Unknown , or None ).
• Distance - Port transmission distance ( <=50m , 50M - 2k ,
2k - 10k , 10k=> ).
• Media - Type of optical cable used ( Singlemode , multimode
50-micron , multimode 62.5-micron , or Unknown ).
• Speed - Operating speed ( Not Established , 1 Gbps ,
2 Gbps , or 4 Gbps ).
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. To perform the test:
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.
NOTE: A small form factor pluggable (SFP) optical transceiver must be
installed in the port during the test. A device can remain connected
during the test.
