3The following items are included in the unit packaging: PoE Power Rack, power supply module, dummy faceplates and cables. Remove all this material and place aside.

Mounting screws are NOT supplied with the PoE Power Rack. Mounting screws may be obtained from the equipment rack/cabinet supplier.

4It is your option to remove power supply module and dummy faceplates or before installation. Removing them makes the next step easier. Refer to Figure 8.

5Install the chassis into the 19-inch equipment rack or cabinet, using at least four screws. See Figure 9.

At least four screws must be used to ensure the PoE Power Rack is securely mounted in the equipment rack or cabinet. Failure to use four screws may cause damage to the PoE Power Rack.

When using an electric screwdriver, the correct torque setting recommended is 6.2 to 6.5 Newton meters. Do not over tighten the mounting screws.
