Installing The Switch; Before You Begin - Allied Telesyn AT-8900 Serie Guía De Instalación Y Seguridad

AT-8900, AT-9900, AT-9900s Series Switches

Installing the Switch

The switch is heavier at the rear than at the front. Therefore, we recommend
that you use the supplied 19-inch rack-mount kit to fully support the switch in a
rack. Using this kit is essential if the front mounting flange on the rack is easily
bent, or the switch is installed in areas subject to shocks such as earth tremors
or heavy vibrations.
