Chapter 2: Installing the Hardware

Planning the Installation of a Stack

Observe these requirements when planning the installation of the stack.

Note

The switches of a stack should be installed in a standard 19-inch

equipment rack. Installing the switches on a table or desktop is not

recommended because it may create a hazardous work area.

 The AT-9424Ts, AT-9424Ts/XP, and AT-9448Ts/XP Switches are the

only AT-9400 Switches that support the stacking feature.

 Each switch must have the AT-StackXG Stacking Module.

 Because of the 0.5 meter length of the AT-StackXG/.5 Stacking Cable,

the switches must be installed in the same equipment rack.

 If the stack will include the optional AT-StackXG/1 Stacking Cable, the

distance between the top and bottom switches of the stack must not be

greater than one meter.

 The order of the devices in a stack that has both 24-port and 48-port

switches is not important.

 Check to be sure the equipment rack is safely secured and will not tip

over. Devices in a rack should be installed starting at the bottom, with

the heavier devices near the bottom of the rack.

 The power outlet for the switches should be located near the units and

be easily accessible.

 The site should provide easy access to the ports on the front of the

switches. This will make it easy for you to connect and disconnect

cables, as well as view the system LEDs.

 To allow proper cooling of the switches, air flow around the units and

through the cooling vents on the sides and rears should be

unrestricted.

 Do not place objects on top of the switches.

 Do not expose the switches to moisture or water.

 Make sure the site is a dust-free environment.

 Use dedicated power circuits or power conditioners to supply reliable

electrical power to the network devices.
