Alpine 3800 Series Switch Power Supplies
4 Remove the DC power and ground cables from the power supply.
5 Slide the locking safety latch on the power supply in the direction marked "remove."
CAUTION
Ensure that the latch is in the remove position. You cannot remove the power supply unless the latch
is in the remove position.
6 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 connections 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.
7 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.
8 If you are going to install a replacement power supply, follow the installation steps on page 147.
9 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.
10 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 DC Power Supply

The Alpine 3802 switch supports two DC power supplies that come preinstalled from the factory. This
section describes the steps to successfully power your Alpine 3802 DC power supplies:
• Selecting the cabling
• Attaching the cabling and supplying power
• Verifying a successful installation
For centralized DC power connections, install only in a restricted access area.
NOTE
Ground the rack, mount the chassis in a rack, and ground the chassis before supplying power to the
power supplies. 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.
In the event of a power supply failure, please contact Extreme Networks about servicing and replacing
your power supply.
