26.3.5Operation
The two LEDs on the fiber interface provide 
information about the status of the fiber interface.
26.4 Installation
The fiber interface can be attached to a wall or any 
other flat surface using a bracket (see figure 26.10). The 
distance between the holes in the bracket is 40 mm.
Mounting of this bracket and the unit on a drywall sheet 
construction requires screws with a minimum screw 
length of 22 mm (7/8") and a minimum diameter of 
2.5 mm (3/32"). Mounting was evaluated for use on a 
drywall surface only.
