Figure 3-13. Replacing a System Fan
Air Shroud
The air shroud is used to concentrate airflow to maximize fan efficiency. The air shroud does
not require screws to set up.
Installing the Air Shroud
1. Lay the chassis on a flat, stable surface and remove the chassis cover.
2. If necessary, move any cables that interfere with the air shroud placement.
3. Place the air shroud in the chassis. The air shroud fits just behind the fans. Slide the air
shroud into the grooves just behind the fan rack.
4. Reroute any cables that were moved and replace the chassis cover.
Power Supply
The 5019S-MN4 has a single high-efficiency power supply, which is auto-switching capable.
This enables it to automatically sense and operate with a 100V to 240V input voltage.
Power Supply Failure
If the power supply unit fails, the system will shut down and you will need to replace the unit.
Replacement units can be ordered directly from Supermicro (see contact information in the
Preface).
Removing the Power Supply
Begin by removing power from the system as described in Section 3.1.
1. Releasing the retention screws that secure the chassis to the rack, then grasp the two
handles on either side and pull the system straight out until it locks (you will hear a
"click").
2. Next, remove the top chassis cover as described in Section 3.2.
3. To remove the failed power unit, remove the two screws on the back and the single
screw on the front of the power supply, which secure it to the chassis. You can then lift
the unit straight out of the chassis.
Installing a New Power Supply
1. Replace the failed power supply with another identical power supply module (exact
same model).
2. Carefully insert the new module into position in the chassis and secure it with the three
screws you removed previously.
3. Reconnect the AC power cord.
4. Replace the chassis top cover and push the server back into the rack.
5. Finish by pressing the power button on the control panel.
Note: the figure above is for illustrative purposes only. The 5019S-MN4 features a single
power supply only.
