Installing The Chassis - Extreme Networks Summit Summit1i Hardware Installation Manual

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.

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.
