2.3.2 Mounting the Chassis on a Rack
Make sure that nothing obstructs the airflow of the chassis.
• If you are facing the OLT front panel, the fan tray located in the left of the OLT chassis houses fans to
blow air for ventilation. Cool air enters the chassis through intake vents on the left side panel and flows
towards the right side where it exits.
Figure 11 Airflow
Use the following procedure to install the chassis in the rack.
1
Position a mounting bracket on one side of the chassis, making sure the screw holes on the bracket are
on the same side as the front panel of the chassis.
2
Use the screwdriver to install the screws through the mounting bracket holes into the chassis.
3
Repeat steps 1 - 2 to attach the second mounting bracket on the other side of the chassis.
