Alpine 3800 Series Switch Power Supplies

6 If you are going to install a replacement power supply, follow the installation steps on page 142.

7 If there is a problem with the power supply that you removed, contact Extreme Networks for

assistance. Do not attempt to fix a faulty power supply. Personal injury to yourself or others may

occur.

8 Leave the ESD strap permanently connected to the chassis so that it is always available when you

need to handle ESD-sensitive components.

Supplying Power to the Alpine 3802 AC Power Supply

The Alpine 3802 switch supports up to two AC power supplies that come preinstalled from the factory.

NOTE

Ground the rack, mount the chassis in a rack, and ground the chassis before installing any switch

components. For more information about grounding the rack, see “Protective Grounding for the Rack” on

page 52. For more information about grounding the chassis, see “Grounding the Alpine 3800 Series

Chassis” on page 138.

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, and

the MGMT LED flashes. 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.
