Alpine 3800 Series Switch Chassis
On/Off Switch
The Alpine 3802 switch supports two DC power supplies, and each power supply has its own on/off 
switch. If you have both power supplies powered on, they provide a redundant, load-shared power 
supply to the Alpine 3802 switch. If one of the power supplies fails, the second power supply provides 
all power and ensures uninterrupted network operation. 
Connect each power supply to different, independent power sources. If a power source fails, it will only 
affect the switch power supply to which it is connected. If all switch power supplies are connected to a 
single power source, the entire switch is vulnerable to a power source failure.
NOTE
Do not attempt to fix a failed power supply; power supplies are not user removable. Alpine 3802 switch 
power supplies must be installed or removed by trained service personnel only. Contact Extreme 
Networks Customer Support if you experience problems.
If you require DC power, you must have two DC power supplies installed in the chassis. 
Installing the Chassis
The Alpine 3800 series chassis fits in standard 19-inch (48.26 cm) racks. Table 37 displays the height 
measurements for the Alpine 3800 series chassis.
The Alpine 3808 and Alpine 3804 chassis are shipped with a preinstalled fan tray. For your safety, due 
to the increased weight of the chassis after components are installed and to prevent damage to the 
equipment, Extreme Networks strongly recommends that you install the power supply and modules 
after you mount the chassis in a rack.

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