3.14 FRU Replacements
3.14.1 Power Supply
Mellanox systems that are equipped with two replaceable power supply units work in a redundant configuration. Either unit may be
extracted without bringing down the system.
To extract a power supply unit:
Remove the power cord from the power supply unit.
The following information does not apply to the SN2100/SN2010 series. The SN2100/SN2010 systems include two non-
replaceable power supply units and four non-replaceable fan units.
Make sure that the power supply unit that you are NOT replacing is showing green for the power supply unit LED.
Power supply units have directional air flows similar to the fan module. The fan module airflow must coincide with the
airflow of all of the power supply units. If the power supply unit airflow direction is different from the fan module airflow
direction, the system’s internal temperature will be affected. For power supply unit air flow direction, refer to Air Flow.
The power supply slots of SN2740 and SN2410 should not be left empty for more than 5 minutes.
