WARNING!
The Altitude 300-2 is not secured to the bracket unless a padlock is used. If a padlock is not used the
unit should be secured to the bracket by a cable tie through the lock hasp.
Mounting Above The Hanging Ceiling
The Altitude 300-2d is compliant with UL 2043 for installation in the plenum area above a hanging
ceiling. Make sure that the Ethernet cable used to connect to the unit is also plenum rated, according to
the National Electric Code, NEC, Section 300-22(C). Equipment above the hanging ceiling should be
secured to the T-bars using a box hanger (not supplied). The universal mounting bracket has been
designed to work with box hangers such as those from B-Line or Caddy (Figure 10).
The follow sources provide T-bar box hangers:
• B-Line model: BA50A, www.cooperbline.com
• Caddy model: 512-BU, www.erico.com
External antennas are recommended for installations above the ceiling. Determine where the external
antenna will be located and the appropriate orientation. Select a site above the ceiling for the Altitude
300-2d that is within reach of the external antenna’s cables. Install the box hanger or remove the box
and install the bracket directly onto the box hanger bar using the fastener provided by the
manufacturer. Make sure all the fasteners are tight before mounting the Altitude 300-2 on the bracket.
The Altitude 300-2 should be secured to the bracket using either a padlock or a cable tie.
Connect the external antenna cables and the powered Ethernet cable to the Altitude 300-2d.
WARNING!
The Altitude 300-2 is not secured to the bracket unless a padlock is used. If a padlock is not used the
unit should be secured to the bracket by a cable tie through the lock hasp. Failure to secure the unit is
hazardous.
WARNING!
The plastic cover and the antenna shrouds have not been tested for use in a plenum space. Do not use
them for above the ceiling installations.
