Media-related issues
This section provides procedures that help pinpoint any media-related issues, such as bad cables
and SFPs, in the fabric. The tests listed in Table 6 are a combination of structural and functional
tests that can be used to provide an overview of the hardware components and help identify
media-related issues.
• Structural tests perform basic testing of the switch circuit. If a structural test fails, replace the
main board or port blade.
• Functional tests verify the intended operational behavior of the switch by running frames
through ports or bypass circuitry.
