Removing the Alpine 3808 and the Alpine 3804 AC Power Supply

Extreme Networks Consolidated Hardware Guide 145

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.

Removing the Alpine 3808 and the Alpine 3804

AC Power Supply

You need the following tools and equipment to remove the Alpine 3808 and the Alpine 3804 AC power

supplies:

• ESD-preventive wrist strap

• # 2 Phillips screwdriver

• Replacement AC power supply

To remove an AC power supply from the Alpine 3808 or the Alpine 3804 switch:

1 Remove the AC power cable from the wall outlet and then from the power supply.

2 Attach the ESD strap that is provided to your wrist and connect the metal end of the ESD strap to

the ground receptacle that is located on the top-right corner of the switch front panel.

3 Slide the safety latch to the left to cover the power connector.

CAUTION

Ensure that the latch covers the AC power connector. The power supply cannot be removed unless

the connector is covered.

4 Use a #2 Phillips screwdriver to unscrew the screw on the ejector/injector lever then pull the

ejector/injector lever towards you to disengage the power supply connectors from the backplane.

Hold on to the central handle to steady the power supply.

CAUTION

When you remove a power supply, use one hand to support the power supply from the bottom and

the other hand to hold the central handle on the front of the power supply. Do not use just the

ejector/injector lever to remove a power supply.

5 Use one hand on the central handle to slowly pull the power supply towards you. Place your other

hand beneath the power supply to support it as you pull it out of the chassis.
