Installing the Power Supply

This section describes how to install a DC power supply for either the Alpine 3808 switch or the Alpine
3804 switch.
Complete the following tasks before installing power supplies:
• Ground the rack (see "Protective Grounding for the Rack (Alpine and BlackDiamond Switches)" on
page 40).
• Mount the chassis in a rack (see "Installing the Chassis in a Rack" on page 152).
• Ground the chassis (see "Grounding the Alpine 3800 Series Chassis" on page 155).
You need the following tools and equipment to install the Alpine 3808 and the Alpine 3804 DC power
supplies:
• ESD-preventive wrist strap
• # 2 Phillips screwdriver
• 1/4-inch or 5/16-inch flathead screwdriver to connect power cables
To install an Alpine 3808 or Alpine 3804 DC power supply:
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 If a blank faceplate is covering the power supply bay, remove it and save it for future use.
3 Prepare the power supply for installation, as shown in Figure 89 and Figure 90:
• Use the text on the front of the power supply to ensure that it is oriented correctly for either the
Alpine 3808 or Alpine 3804.
• Open the ejector/injector lever.
• Move the safety latch to the "remove" position.
• Place the On/Off switch in the "off" position.
