Requirements for Rack Installations

The T1 Modem Bank chassis is made to be inserted into a standard 19-inch or a 24-inch equipment rack. The T1 Modem Bank is shipped from the factory with two rack-mounting brackets (“ears”) installed for a 19-inch rack. If you wish to install a T1 Modem Bank into a 19-inch rack, go now to the instructions in “General Rack Installation Directions” on page 14. Before you can install a T1 Modem Bank into a 24-inch rack, you must first remove the rack-mounting brackets and then re-install them in the correct position for a 24-inch rack.
