2.10 FRU Replacements
2.10.1 Power Supply and Fans
2.10.1.1 Power Supply
Mellanox systems equipped with two replaceable power supply units work in a redundant config-
uration. Either unit may be extracted without bringing down the system.
 To extract a power supply unit:
Step 1.
Remove the power cord from the power supply unit.
Never run the system more than 5 minutes with an uncovered (open) PSU or fan slot.
This section does not apply to SX1012/SX1012X
Make sure that the power supply unit that you are NOT replacing is showing all green,
for both the power supply unit and System Status LEDs.
Power supply units have directional air flows similar to the fan module. The fan mod-
ule 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 Section 2.2 on page 18.
