OLT Installation

Unpacking and Checking the OLT2

The Tellabs OLT2 and related accessories to be installed may arrive in a single shipping box, or in multiple boxes. When unpacking the boxes, check each item against the installation work order for proper quantities and for shipping damage.

• If a shortage or damage is found, contact the Tellabs Technical Assistance Center (TAC) immediately.
• If all items are accounted for and in good condition, installation can proceed.

Installing the OLT2

Installing the Tellabs OLT2 consists of the following steps.

1. The physical installation:
   • Mounting the OLT2 to a wall, or some other surface
   • Mounting the OLT2 in a rack mount
2. Connecting the OLT2 to DC power:
   • AC adapter at the installation location
   • Remote bulk DC power supply cable

Physical Installation

Desktop Mount

Attach the supplied rubber feet to the dimpled positions on the bottom of the OLT. 

Note: the OLT2 is delivered with the rack mounting brackets installed. They can be removed for a desktop mount.

Mounted to a Wall

The OLT2 can be attached to a wall, or to some other surface using a Wall Mounting Bracket and screws.

Note: Make sure that the owner of the building or the owner of the individual unit or furniture is aware that holes will be drilled and screws and/or wall anchors will be used to mount the OLT to a wall or other surface before beginning installation.

Before mounting the OLT2, decide on the best orientation for access and ease of use.

1. Remove the rack mounting brackets from the OLT front panel and attach the brackets to the sides of the OLT.
   
   
    
2. Place the OLT2 on the surface it will be attached to. Position the bracket so that it will hold the OLT in the desired orientation.
3. Select at least two holes in the bottom of the bracket and mark the mounting surface.
4. Carefully drill holes in the marked locations appropriate for the fasteners that will be used.
5. Install drywall or masonry anchors in their holes if they will be used.
6. Hold the OLT2 in position and secure with #10 screws through the selected holes.
7. Install the fiber management guides (recommended) in a proper location on the wall surface.
8. Construct and position a chassis ground cable using a #10AWG stranded wire with a Green/Yellow sheath.
   1. Connect the chassis ground cable to the single-hole lug on the side of the OLT2 (Phillps M3.5 6 long) and to the facilities ground. See Figure below.
      
      
       

Rack Mount Installation

Single OLT2 Panel Assembly

1. Attach the Connector Bracket to the OLT2 front panel with two supplied screws.
2. Attach the Blank Panel to the Connector Bracket with two supplied screws.

Dual OLT2 Panel Assembly

The panel is assembled using an OLT2 19" Rackmount Kit (81.11K-OLT2-RACK19) and comprises one blank panel and connector bracket with hardware.

1. Attach the Connector Bracket to the OLT2 front panel with two supplied screws.
2. Attach the Second OLT2 to the Connector Bracket with two supplied screws.

Installation in Rack

Use the following instructions to install Tellabs OLT2: 

1. Insert the OLT2 shelf into the desired position and push it straight back until the mounting brackets are flush against the mounting rails.
2. Secure the OLT2 shelf with four #12-24 screws. Inserting the two upper mounting screws first. Do not tighten the mounting screws until Step 3 has been completed. 
3. If good grounding cannot be achieved by installing the OLT2 in a rack, a chassis ground connection can be made using the single-hole grounding location on the side of the OLT2.
   1. Construct and position a chassis ground cable using a #10AWG stranded wire with a Green/Yellow sheath.
   2. Connect the chassis ground cable to the single-hole lug on the side of the OLT2 (Phillps M3.5 6 long), See Figure below.
      
      
       
   3. The terminating end of the chassis ground cable connection should be secured to the rack frame by using a ring connector (12-10 AWG). 
   4. Remove the paint from a rail mounting hole adjacent to the left-hand corner of the unit and connect the frame ground to the equipment rail. The paint must be removed to ensure a good electrical connection to ground.
4. Secure the shelf using two screws. Insert the first upper top mounting screws. Do not tighten the screws until step 5 has been completed.
5. Insert the remaining screws into the mounting holes and tighten as required to ensure the OLT2 shelf is secure.
6. Refer to Power Up the Tellabs OLT2 for details on the OLT2 power-up sequence.
