Chapter 5 Cisco SFS 3012R Server Switch LEDs

InfiniBand LEDs

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.
