T1 Modem Bank Standalone or Rack Installation

You have the option of using the T1 Modem Bank in a standalone, table-top configuration or in a rack-mounted configuration. Directions for both configurations are provided in this section.

∙ Make sure the T1 Modem Bank is powered-down before you install it.

∙Do not block the sides of the T1 Modem Bank since this will impede airflow.

∙The T1 Modem Bank is shipped from the factory with four “feet” installed on the bottom of the unit. If you remove the feet, you must ensure that the T1 Modem Bank will have at least 1U (1.75 inches) of clearance beneath it in order to prevent airflow from being impeded.
