Overview
These expansion modules provide optional uplink ports for the AT-8000
Series Fast Ethernet Switches. They are designed for the two expansion slots
on the front of the switches. The expansion modules, which can be installed in
any combination and without having to power OFF the switch, offer flexibility
in building or expanding your network. A maximum of two expansion modules
can be installed in a switch.

Caution
Before installing an expansion module, refer to the PDF document titled
“Translated Safety Statements V2” (613-000990) located on the Allied
Telesis website at www.alliedtelesis.com, for electrical safety and
emission information.
This section describes how to install an optional expansion module. To install
an expansion module, follow these steps:
1. Unpack the module from its shipping container and store the packaging
material in a safe location.
Note
You must use the original shipping material if you need to return the
module to Allied Telesis.
2. Check that the module package includes all the items listed in section
Package Contents. If any item is missing or damaged, contact your Allied
Telesis sales representative for assistance.
3. Select a switch where you will install the expansion module.
4. Face the front panel of the switch and locate the expansion slots (left side
of switch).
5. To remove an expansion slot faceplate, using a Phillips screwdriver,
carefully loosen the installation screws found on the left and right sides of
the faceplate, as displayed below. An expansion module can be installed
in either expansion slot.
Caution
Be sure to observe all standard electrostatic discharge (ESD)
precautions, such as wearing an antistatic wrist strap, to avoid
damaging the device. If removing an expansion module, store the
module in an antistatic bag or immediately install it in another switch. An
expansion module can be damaged by static electricity.

6. Remove the faceplate from the slot.
Keep the faceplate in a safe area in case you need to install it in the slot
again. The faceplate will keep any dust from getting into the switch and
will maintain proper airflow if the slot remains empty.
7. Carefully slide the expansion module into the slot until the expansion
module faceplate makes contact with the switch, as displayed below.
Avoid touching the expansion module components.
