Alpine 3802 Switch
Extreme Networks Consolidated "e" and "i" Series Hardware Installation Guide 149
Connect each power supply to different, independent power sources. If a power source fails, it will
affect only the 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 repair a failed power supply; power supplies are not user-removable. Alpine 3802
switch power supplies must be installed or removed only by trained service personnel. Contact Extreme
Networks Customer Support if you experience problems.
