Planning the Installation of a Stack

38
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 switch and the bottom switch of the stack
must not be greater than one meter.

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.
