Figure 16 Attaching Mounting Brackets
4 Position a mounting bracket (that is already attached to the chassis) on one side of the rack, lining
up the screw holes on the bracket with the screw holes on the side of the rack.
5 Use the screwdriver to install the screws through the mounting bracket holes into the rack.
6 Repeat steps 4-5 to attach the second mounting bracket on the other side of the rack.
2.2.3 Connecting the OLT Frame Grounds
Frame grounds help protect against lightning and interference functions. Use M4 machine screws
with suitable lock washers to attach the frame ground cable to the OLT. The other end must be
securely fastened to the chassis ground with a lug and screw arrangement of M3.5 or greater.
The OLT frame grounds are on the upper right corner of the front panel.
Connect the frame grounds to a building’s protective earthing terminals using a green-and-yellow
frame ground wire.
Warning! Connect the frame grounds before you connect any other
cables or wiring.
