Replacing the Alpine 3800 Series 
Switch Fan Tray
This chapter provides instructions for replacing the fan tray in the Alpine 3808 or Alpine 3804 switch. 
The chapter includes the following topics:
NOTE
Read the information in this chapter thoroughly before you attempt to install or remove any Alpine fan 
tray. The fan tray in the Alpine 3802 is not designed to be replaced by customers. Contact Extreme 
Networks if there is a fan failure in the Alpine 3802.
Removing the Alpine 3808 or Alpine 3804 Fan Tray
You do not need to turn off power to an Alpine 3808 or Alpine 3804 switch to remove a fan tray.
You need the following tools and equipment to remove a fan tray:
ESD-preventive wrist strap
# 1 Phillips screwdriver
Replacement fan tray
CAUTION
Only trained service personnel should perform service to Alpine 3800 series equipment. Before 
installing or removing any components, or carrying out any maintenance procedures, see Appendix A
.
To remove the fan tray from the Alpine 3808 or Alpine 3804 switch:
1
Attach the ESD strap to your wrist and connect the metal end to the ground receptacle on the top 
right corner of the switch front panel.
2
Using the # 1 Phillips screwdriver, loosen the captive screws that secure the fan tray to the chassis.
3
Use the finger grips to pull the fan tray out of the chassis approximately 1 inch (2.54 cm), as shown 
in Figure 116 and Figure 117; this step disconnects the power and causes the fans to stop rotating.
