Removing an Alpine 3808 or Alpine 3804 Fan Tray
Caution: Do not cover or obstruct the fan ventilation holes at the rear of the unit.
Doing so can result in overheating and possible damage to the Alpine 3802
switch. Thermal sensors will shut down the Alpine 3802 switch if the internal
temperature exceeds 60 degrees Celsius.
Note: In the event of a fan tray failure, please contact Extreme Networks.
ExtremeWare monitors the fan trays in the Alpine 3802 switch for overheat conditions.
All over temperature events cause the switch to send alerts to the network management
station or to the switch log. See the ExtremeWare Software User Guide for more
information about switch monitoring.
Removing an Alpine 3808 or Alpine 3804
Fan Tray
To remove a fan tray from the Alpine 3808 or Alpine 3804 switch:
1 Attach the ESD strap that is provided to your wrist and connect the metal end to the
ground receptacle that is located on the top-right corner of the switch front panel.
2 Unscrew the two captive screws that secure the fan tray to the chassis by turning
them counterclockwise (to the left).
3 Use the finger grips to pull the fan tray out of the chassis approximately 1-inch
(2.54-cm), as shown in Figure 11-1 and Figure 11-2; this step disconnects the power
and causes the fans to stop rotating.
4 Allow the fan blades to stop spinning before you remove the fan tray from its slot.
Warning: Keep your hands away from rotating fan blades.
5 Leave the ESD strap permanently connected to the chassis, so that it is always
available when you need to handle ESD-sensitive components.
