The AT-A1xSeries Expansion Modules are optional uplinks for the AT-8216FXL/
MT, AT-8216FXL/VF, AT-8216FXL/SC, and AT-8224XL Fast Ethernet Switches.
The expansion modules are designed to be installed into the two expansion slots
on the front of each switch. The expansion modules, which can be installed in any
combination, offer you flexbility in building or expanding your network.
Figure 1 through Figure 5 show the front panels while Table 1 describes each
expansion module.

Installing the Expansion Module
To install an expansion module, perform the following steps:
1. Disconnect the switch’s power cord, if attached.
Warning
Make sure to disconnect the power cord before installing the expansion
module. Installing an expansion module without doing so can damage
the module.
Warning
The power cord is used as a disconnect device. To de-energize
equipment, disconnect the power cord. !9
2. Remove a blank faceplate from one of the expansion slots by unscrewing
the faceplates two captive screws. Refer to Figure 6. Do not remove the
blank faceplate if you are not installing an expansion module into the
slot.
Figure 6 Removing the Blank Panel
If you are installing only one expansion module in the switch, you should
install the module in slot A. While the module will work in slot B with slot
A empty, the port numbering assignments will change if you later install
a module in slot A. This could affect the VLAN memberships on the
switch and this could require you to adjust your VLAN configurations.
A
B
Captive Screws
Blank Faceplate

Overview
6
For example, if you install an AT-A17 in slot B while leaving slot A empty,
the switch will assign the port numbers 25 and 26 to the ports on the
module. If you later install another AT-A17 in slot A, the switch will
automatically reallocate port numbers 25 and 26 to the new modules in
slot A and assign the port numbers 27 and 28 to the module in slot B. If
the module in slot B had been a member of a VLAN, you would be
required to reconfigure the VLAN to reflect the change to its port
numbers.
3. Remove the expansion module from the packing material. Make sure you
observe ESD precautions.
4. Slide the expansion module into the empty slot making sure the board is
aligned properly with the card guides. Refer to Figure 7.
Figure 7 Installing an Expansion Module
5. Secure the expansion module to the switch by tightening the captive
screws.
6. Apply power to the switch by re-attaching the power cord to the switch.
Verify that the Power LED lights green.
7. Remove the dust cover from the port(s) on the expansion module and
connect the data cable(s).

ChangingtheGBICModuleintheAT-A15/SXorAT-A15/LXExpansion
Module
The AT-A15 (SX or LX) expansion module can be equipped with the AT-G8SX
GBIC module for LED transmission of up to 1,804 ft (550 m) or the AT-G8LX
GBIC module for laser transmission of up to 16,400 ft (5 km).
This procedure explains how to change the GBIC module in an AT-A15 (SX or
LX) module. The procedure assumes that the expansion module has been
installed in the switch. If you have not installed the AT-A15 (SX or LX) module in
the switch, refer to “Installing the Expansion Module” on page 5. To change the
GBIC module, perform the following procedure:
1. Remove the fiber cables from both ports of the module, if attached.
Laser
Do not stare into the laser beam. !7
2. Remove the GBIC module from the AT-A15 (SX or LX) expansion
module by pulling up the release wire and sliding the module out of the
expansion slot. Refer to Figure 8.

4. Remove the dust cover and attach the fiber cables. It is important to leave
the dust cover in place if you are not attaching the cables at this time.
Dust in the ports will degrade transmission.
5. Apply power to the switch by re-attaching the power cord. Verify that the
Power LED lights green.
