3 The 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.
4 It 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.
5 Install 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.
