Installing the Alpine 3800 Series AC Power

Supply

This section describes how to install an AC power supply for either the Alpine 3808 or

the Alpine 3804 switch. The Alpine 3802 switch power supply is preinstalled at the

factory. The power supplies for the Alpine 3808 switch are inserted into the front of the

chassis. The power supplies for the Alpine 3804 switch are inserted into the lower rear

of the chassis.

Note: Mount the chassis in a rack before installing any switch components.

To install the Alpine 3808 and Alpine 3804 AC power supplies:

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 Remove the blank faceplate that is covering the power supply bay.

3 Ensure that the power supply is oriented correctly for either the Alpine 3808 or

Alpine 3804 using the text on the front of the power supply, and ensure that the

ejector/injector lever is open, as shown in Figure 8-1 and Figure 8-2.

Caution: When you insert a power supply, use one hand to support the power

supply from the bottom and the other hand to hold the central handle on the

front of the power supply. Do not use just the ejector/injector lever to insert a

power supply.

4 Use the central handle to guide the first power supply into the power supply bay.
