Alpine 3800 Series Switch Chassis
The rear view of the Alpine 3802 AC switch provides:
• Access to the grounding studs
• The chassis serial number
• The Ethernet MAC address of the switch
• Symbols of safety certification
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).
