The PS LED is flashing.
The PSU is not properly plugged in or not completely seated:
Check the power cord and its connections. Ensure that the cord is connected to the
correct inlet in single-PSU configurations.
Check the installation of the PSU module.
4.
The SYS LED does not illuminate.
Check the status of the PS LED if it is also not illuminated, it is a PSU problem, see Step 1.
If the PS LED is illuminated, it is an over-temperature problem. Reduce the ambient operating
temperature and ensure that the airflow is not impeded. If the condition persists after
correcting any problems, it is likely that a component has failed, and you should call HP
Service.
5.
The SM LED does not illuminate.
The SM LED does not illuminate if the SR 9024 is externally managed (there is no management
card present).
If the SM indicator does not illuminate on an internally managed ISR 9024, the management
card is not running the subnet management software. Call HP service.
6.
The InfiniBand port links do not illuminate, as follows:
The green physical link indicator does not illuminate.
The green physical link indicator is illuminated, but the logical link indicator is not.
These conditions indicate that the InfiniBand cable or its connector is faulty. For both cases,
verify that the cable is connected correctly at both ends. Try swapping the cable with a spare,
or use the cable from an adjacent port temporarily to eliminate the cable as the source of the
problem.
If a known good cable does not correct the problem, there might be a problem with the port
itself. Call HP Service.
