InfiniBand Port LEDs
Two port LEDs (both green) appear next to each InfiniBand port on the switch module, as shown in
Figure 5-6.
Both the top and bottom InfiniBand port LEDs are solid green. The top LED indicates a logical link has
taken place. (A logical link is established when the subnet manager makes a sweep. A logical link must
be established if you are to use the port.) The bottom LED indicates a physical link has occurred. (A
physical link requires that the drivers on the attached InfiniBand host have been installed and are
running).
Table 5-10 explains InfiniBand port LED indications.
