CHAPTER 2
Hardware Installation
This chapter describes how to install and connect the OLT and line cards.
2.1 General Installation Instructions
Perform the installation as follows:
Make sure the OLT’s power switches are in the OFF position.
Install the chassis as detailed in Section 2.2 on page 31, making sure you connect the frame
grounds before you make any other connections.
If line cards are not already installed, see Section 2.3 on page 34 to install them.
Leave the slot covers on unused slots.
•See Section 1.3.2 on page 19 to make alarm connections.
•See Section Figure 20 on page 37 to make power connections and turn on the OLT.
2.2 Chassis Installation
This section explains how to install the chassis on a rack.
2.2.1 Rack-mounted Installation Requirements
Make sure the rack will safely support the combined weight of all the equipment it contains.
Use a #2 Phillips screwdriver to install the screws.
Refer to Section 46.2 on page 316 for the gauge of wire to use for the frame ground connections.
Refer to Section 46.1 on page 315 for the OLT’s dimensions, weights and power consumption.
Failure to use the proper screws may damage the unit.
2.2.2 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.
