Removing the Alpine 3808 or 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 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 Verify that the rack and chassis are grounded to protective earth ground.
4
Slide the safety latch to the left to cover the power connector.
CAUTION
Make sure that the latch covers the AC power connector. The power supply cannot be removed
unless the connector is covered.
5 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.
6 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.
7 If you are going to install a replacement power supply, follow the installation steps on page 160.
8 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.
9 Leave the ESD strap permanently connected to the chassis so that it is always available when you
need to handle ESD-sensitive components.
