Power Sockets
The Alpine 3802 switch supports up to two AC power supplies. Each power supply has its own power 
socket. When a second power supply is installed, both 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.
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 have one power supply installed in the Alpine 3802, it must be installed in the lower power 
supply tray (PSU A). 
Alpine 3802 DC Rear View
For centralized DC power connections, install only in a restricted access area.
