CHAPTER 7: SCSI Fiber Optic Extender Control: Online
• Self-Test Button: Provides a method for testing the Extender hardware. When
clicked, this will immediately start a self-test on the Extender.
IMPORTANT
A self-test always uses the coax connection for testing. If fiber is used
to connect the Extenders, the coax loopback adapter must be installed
on the Extender. A self-test will temporarily select the coax connection
and turn off the fiber connection to complete the test. Self-test should
not be implemented while there is bus activity on the Extenders. When
you select Self-Test, the light will blink several times and will turn either
green for a successful test or red if errors were encountered.
• Link Test Button: Provides a method for testing the connection between two
Extenders. This is the most common test to ensure proper installation of the
units. When Link Test is selected, the light will blink several times and will turn
either green for a successful test or red if errors were encountered.
• SCSI Activity: A graphical representation of SCSI bus activity. This meter will
rise and fall depending on the amount of the data being transferred across the
SCSI bus.
