Alpine 3800 Series Switch Power Supplies
Selecting the Cabling
Use the following guidelines when selecting cabling for the DC power supplies:
Each DC power supply requires:
30 A (Alpine 3808) at -48 VDC nominal
16.5 A (Alpine 3804) at -48 VDC nominal 
Or equivalent power between -40 and -70 VDC.
For DC power and ground cables, use:
8 AWG, high-strand count copper wire cable (Alpine 3808) 
10 AWG, high-strand-count copper wire cable (Alpine 3804) 
Use power cables with the specifications outlined in Table 41. 
Installing the Power Supply
This section describes how to install a DC power supply for both the Alpine 3808 switch and the Alpine 
3804 switch. 
The Alpine 3802 switch comes with DC power supplies that are preinstalled at the factory; however, 
you must attach the cabling to the DC power supplies. See “Supplying Power to the Alpine 3802 DC 
Power Supply” on page 149 fo
r more information.
NOTE
Ground the rack, mount the chassis in a rack, and ground the chassis before installing any switch 
components.
Complete the following tasks before installing any switch components:
Ground the rack—For more information about grounding the rack, see “Protective Grounding for the 
Rack” on page 46
Mount the chassis in a rack—For more information about mounting the chassis, see “Installing the 
Chassis” on page 132.
