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.
The following procedures are for checking switch-specific components.
Testing a port’s external transmit and receive path
1.
Connect to the switch and log in as admin.
2.
Connect the port you want to test to any other switch port with the cable you want to test.
3.
Enter the
portLoopbackTest -lb_mode 2
command.
Testing a switch’s internal components
1.
Connect to the switch and log in as admin.
2.
Connect the port you want to test to any other switch port with the cable you want to test.
3.
Enter the
portLoopbackTest -lb_mode 5
command where
5
is the operand that causes the test
to run on the internal switch components (this is a partial list—see the
Fabric OS Command
Reference
for additional command information):
