Rack Mounting Total Access 900 Series
The Total Access 912/916/924 products are housed in a 1U-high, rack-mountable chassis that can be
installed into 19-inch or 23-inch equipment racks. For a rackmount installation, optional rackmount
brackets must be purchased (19-inch – P/N 1200927L19, 23-inch – P/N 1200927L23).
The Total Access 912/916/924 mount and connect with standard fasteners and hand tools.
The Total Access 904 and Total Access 908 are not rack mountable.
ADTRAN recommends 1U (1.75 inches) of separation above and below the
Total Access 900 Series unit. This spacing allows the unit to dissipate heat. The design of
the Total Access 900 Series uses the chassis to distribute heat generated by the unit’s
internal cards. This design allows the unit to operate without a cooling fan, thus creating
overall reliability of the unit.
Step 1 : Prepare the
mounting surface by
attaching a board
(typically plywood, 3/4"
to 1" thick) to the wall.
(The board must be
attached to a stud in
the wall for stability.)
Step 2 : Wallmount the
Total Access 900 Series
unit using two 3/32" to
1/8" (1" or greater in
length) wood screws.
