Overview
The AT-BSTACK1 Stacking Module is designed for the AT-8324SX Fast
Ethernet Switch. You use the module to create stacks of up to four switches.
Running at a bandwidth of over 4 Gbps, this module provides a common
interface to the attached switches, allowing the stack to function and be
managed as a single device.
Caution
The stacking module is designed for the AT-8324SX Fast Ethernet
Switch only. Do not install this module in any other Allied Telesyn
device.
Note
One AT-BSTACK1 module must be installed in each AT-8324SX switch
that will be a part of the stack.
For installation instructions for the AT-8324SX switch, refer to the AT-
8324SX Fast Ethernet Switch Installation Guide. For instructions on how to
manage a stack, refer to the AT-S29 Management Software User’s Guide. Both
of these guides are available from the Allied Telesyn web site.

Reviewing Safety Guidelines
Please review the following safety guidelines before you begin to install the
stacking module in the switch.
Warning
Electric Shock Hazard: To prevent electric shock, do not remove the
cover. There are no user-serviceable parts inside. The unit contains
hazardous voltages and should only be opened by a trained and
qualified technician. 4
Warning
Lightning Danger: Do not work on this equipment or cables during
periods of lightning activity. 5
Warning
Power cord is used as a disconnection device: To de-energize
equipment, disconnect the power cord. 6
Warning
Electrical-Type Class 1 Equipment: This equipment must be
earthed. The power plug must be connected to a properly wired earth
ground socket outlet. An improperly wired socket outlet could place
hazardous voltages on accessible metal parts. 7
Caution
Pluggable Equipment: The socket outlet should be installed near the
equipment and should be easily accessible. 8

Caution
Air vents: The air vents must not be blocked on the unit and must have
free access to the room ambient air for cooling. 9
Caution
Operating Temperature: This product is designed for a maximum
ambient temperature of 50°C. 10
Caution
All Countries: Install this product in accordance with local and
National Electric Codes. 11
Handling the Module
Caution
The AT-8324SX Stacking Module can be easily damaged by electrostatic
discharge.
To prevent electrostatic damage, observe the following guidelines:
Wear an anti-static wristband connected to a suitable earth ground
whenever handling the module.
Do not remove the module from its packaging until you are ready to
install it.
Do not touch any of the module’s pins, connectors or components.
Hold the module only by its edges or front panel.
Store or transport this module only in appropriate anti-static
packaging.

Installing the Module
To install the module, perform the following procedure:
1. Power off the switch by disconnecting the AC power cord from the switch.
If the switch is connected to a redundant power unit (RPU), disconnect the
DC cable connection to the switch.
Caution
The switch must be powered off before installing or replacing the
module. Installing the module with the switch powered on can damage
the module.
2. Using a flathead screwdriver, remove the faceplate from the lower left
expansion slot (slot B) on the rear panel of the switch, as shown in Figure 1.
Caution
The AT-BSTACK1 Stacking Module must be installed in the lower left
expansion slot (slot B). Installing the module in any other expansion slot
can damage the module.
Figure 1 Removing the Faceplate
Note
Keep the original faceplate for future use. If you should remove the
module, replace the faceplate to prevent dust and debris from entering
the unit and to maintain proper air flow.
Caution
Be sure to wear an anti-static wristband before performing the next
step. This is to prevent damaging the AT-BSTACK1 module.

3. Insert the AT-BSTACK1 module into the expansion slot, as shown in
Figure 2. Holding the new module with the text on the front panel upright,
carefully slide the module into the switch slot, ensuring that the edge
connector is fully engaged. Once the module is installed, check to be sure
that the front panel of the module is flush against the switch.
Figure 2 Installing the Module
4. Secure the new module in place with the attached screws.
5. Connect the stack cables to the AT-BSTACK1 Stacking Modules, as shown
in Figure 3. Attach one end of the stacking cable to the stack connector
labeled "DOWN" on the top device, and the other end to the connector
labeled "UP" on the next lower device. Repeat this step until all the
switches have been connected.
Note
The switch with the AT-BMGMT Management Module must be either
the top or the bottom unit of the stack.

6
Figure 3 Cabling the Switches
6. Power on the switch by reconnecting the previously removed power sources
to the switch. The module port LEDs on the front-panel of the switches
should indicate their status. The Status LED should be On, indicating the
presence of the AT-BSTACK1 module. Refer to the AT-8324SX Fast
Ethernet Switch Installation Guide for a description of all the system
LEDs. If the stack is not functioning properly, see "Troubleshooting"
below.
More details concerning connection options and network applications can be
found in the AT-8324SX Fast Ethernet Switch Installation Guide. Information
on managing the stack can be found in the AT-S29 Management Software
User’s Guide.

Troubleshooting
If you experience any problems with the module, check the following items
before contacting Allied Telesyn Technical Support:
Ensure that all the switches in the stack are powered up.
Ensure that the devices attached to the stack are powered up and
operating correctly.
Ensure that the stack modules are properly seated in their slots.
Check the connectors on both ends of the stack cable to be sure they
are properly engaged. Tighten the thumb screws on the cable
connectors to ensure a good connection.
