CAUTION
Only trained service personnel should perform service to Alpine 3808 or Alpine 3804 fan trays. 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 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 Check the connectors for dust and packing materials.
3 To support the fan tray, place one hand under the fan tray and use the other hand to guide the fan
tray into the slot. Gently begin to 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 To secure the fan tray, turn the screws clockwise until they become tight.
5 Leave the ESD strap permanently connected to the chassis so that it is always available when you
need to handle ESD-sensitive components.
