3.4 REMOVING AND REINSTALLING THE FAN TRAY
The N3 chassis is factory equipped with a removable fan tray 7C403. This allows for easy periodic
cleaning and/or replacement if a problem occurs with fan operation. A flat blade screwdriver is
needed to remove and reinstall the fan tray. To remove and reinstall the fan tray, refer to
Section 3.4.1 and Section 3.4.2.
3.4.1 Removing the Fan Tray
To remove the fan tray, refer to Figure 3-7 and proceed as follows:
1. Locate the ESD wrist strap shipped with the chassis. Attach the ESD wrist strap to your wrist
and plug the cable from the ESD wrist strap into the ESD grounding receptacle at the front-upper
right corner of the chassis.
2. While holding the fan tray in place against the rear of the chassis, use a flat blade screwdriver to
loosen the four captive screws that secure the fan tray to the rear of the chassis.
3. Using the fan tray handles, pull the fan tray straight out and away from the chassis.
Caution: The fan tray is hot swappable. However, do not run the chassis for extended periods of
time without the fan tray, as the chassis will quickly overheat and cause component damage.
Precaución: El sistema de ventilación se puede reemplazar cuando la unidad está encendida.
Sin embargo, no utilice el chasis durante largos períodos sin contar con un sistema de ventilación
porque podría sobrecalentarse y dañarse.
