Power Supply Installation

OLT2 Power 

Power for the OLT is supplied by a 150W Power Supply (81.11P-PWIL150W) using an AC power cord (81.11W-C5TYPB-R6) on one end and an 8-pin Molex connector "A" or "B" power connector on the back of the OLT2. Two power supplies may be installed for a "redundant" configuration.

Power Supply Connections
 

Network Powered Systems

1. For network-powered systems, the Low Voltage Remote Power Cable (81.11W-2W8M) connects into the "A" or "B" power connector on the back of the OLT2. It comes with two quick connectors.
2. In the bulk DC power supply, turn off or disconnect the DC power for the cable connecting to the location where the OLT is being installed.

   Note: Make note which wire (color/stripe/etc.) is positive on the bulk wire cable.

3. Route the bulk DC power cable to within 8" of the OLT rear. Return to the bulk DC power supply location and use a DMM to make sure that there is no voltage on the wires of the remote bulk DC cable before proceeding further.
4. Strip about 3/16 inch of insulation from the ends of the remote bulk DC cable and twist the strands of each wire tightly.
5. Connect the two (2) wires of the bulk DC cable to the 8 pin Molex quick connect cable (P1) by joining with insulated butt connectors (18-22 AWG).
   
   
    
6. Connect the P1 connector to the OLT when directed in the Power Up section.

Power Supply Mounting

The power supply can be wall mounted with a snap-in power supply mounting bracket (81.11K BKONTPS 150).

Power Supply Mounting Bracket

1. Place the mounting bracket on the surface it will be attached to. Position the bracket so that it will hold the power supply in the desired orientation.
2. Select at least two holes in the bottom of the bracket and mark the mounting surface.
3. Carefully drill holes in the marked locations appropriate for the fasteners that will be used.
4. Install drywall or masonry anchors in their holes if they are used.
5. Hold the bracket in position and secure with #10 screws through the selected holes.
