Installing the Alpine 3808 or Alpine 3804 Fan Tray
Alpine 3808 and Alpine 3804 fan trays are hot-swappable. You do not need to turn off power to an
Alpine 3808 or Alpine 3804 switch to install a fan tray.
You need the following tools and equipment to install a fan tray:
• ESD-preventive wrist strap
• # 1 Phillips screwdriver
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 install the fan tray in 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 Check the connectors for dust and packing materials.
3 Support the fan tray with one hand under the fan tray, and use the other hand to guide the fan tray
into the slot.
Carefully insert the new fan tray into the slot.
NOTE
If the chassis is powered on, the fan blades will begin turning as soon as the tray makes contact with
the backplane.
4 Using the # 1 Phillips screwdriver, align and tighten the retaining screws to secure the fan tray, to the
chassis.
Leave the ESD strap permanently connected to the chassis so that it is always available when you need
to handle ESD-sensitive components.
