•
Mount the chassis in a rack—For more information about mounting the chassis, see “Installing the
Chassis” on page 132.
• Ground the chassis—For more information about grounding the chassis, see “Grounding the Alpine
3800 Series Chassis” on page 135.
To turn on power to the system, connect the power cable to the power supply and then to the wall
outlet.
In the event of a power supply failure, please contact Extreme Networks about servicing and replacing
your power supply.
NOTE
Alpine 3802 power supplies must be removed and replaced by personnel that have been trained by
Extreme Networks.
Verifying a Successful Installation
After you supply power to the Alpine switch, the switch performs a power-on self test (POST).
During the POST:
• All ports are temporarily disabled
• The packet LED is off
• The power LED is on
• The MGMT LED flashes until the switch successfully passes the POST
If the switch passes the POST, the MGMT LED blinks at a slow rate (one blink per second). If the switch
fails the POST, the MGMT LED shows a solid yellow light.
NOTE
See Chapter 9, “Alpine 3800 Series Switch Management Module” for more information about switch
management module LED activity and Chapter 10, “Alpine 3800 Series I/O Modules” for more
information about I/O module LED activity.
