Installing the AT-RPS3204 Redundant Power Supply To install an AT-RPS3204 Redundant Power Supply (RPS), perform the following procedure: 1. Remove the RPS from its shipping package and store the package in a safe place. You must use the original shipping package if you need to return the RPS to Allied Telesis. 2. If you are installing the RPS in a rack, place the unit upside down on a level, secure surface. If you are not installing the RPS in a rack, go to step 5. 3. Use a flat-head screwdriver to remove the snap-on feet from the bottom of the power supply. 4. Turn the power supply over. 5. Locate the power cord retaining clips. 6. Locate the retaining bracket on each side of the two AC power connectors on the back of the power supply. 7. With the “u” of the clip facing up, press the sides of the clip toward the center and insert the short ends into the holes in one of the retaining brackets. 8. Repeat steps 6 and 7 to install the second retaining clip in the other retaining bracket. 9. Verify that the retaining clips are in the correct position. 10. Attach a rack-mount bracket to one side of the front of the RPS, using a # 1 Phillips screwdriver and six rack-mount screws provided in the package. If you are not installing the unit in a rack, go to step 13. 11. Install the second rack-mount bracket on the other side of the RPS, using the remaining rack-mount screws. 12. Mount the AT-RPS3204 in a 19-inch rack using standard screws (not provided). 187 AT-PWR3202 STATUS POWER FAULT 12VDC ,10A MAX B2 RPS OUTPUT B2 12VDC AC INPUT B2/B1 100 - 240 VAC ~ RPS OUTPUT B1 12VDC RPS OUTPUT A2 12VDC B1 A2 RPS OUTPUT A1 12VDC AC INPUT A2/A1 100 - 240 VAC ~ A1 ON OFF ON OFF ON OFF AT-RPS3204 188 WARNING This unit has more than one power input.

E6 Warning: Operating Temperature. This product is designed for a maximum ambient temperature of 40° C. E7 All Countries: Install product in accordance with local and National Electrical Codes. E8 Circuit Overloading: Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern. E21 Warning: Mounting of the equipment in the rack should be such that a hazardous condition is not created due to uneven mechanical loading. E25 If installed in a closed or multi-unit rack assembly, the ambient temperature of the rack environment may be greater than the room ambient temperature. Therefore, consideration should be given to installing the equipment in an environment compatible with the manufacturer’s maximum rated ambient temperature (Tmra). E35 Caution: Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised. E36 Warning: Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuits (e.g., use of power strips). E37 Warning: High leakage current due to multiple power supplies. Connection of each power cord to a separate branch circuit with proper earth connections is essential. 193 4 5 6 13.
