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.

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.

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.
