AT-RPS3204 Redundant Power Supply Installation Guide
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.
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).
Overview
The AT-RPS3204 powers an Allied Telesis switch if the switch’s main power
supply fails. The AT-RPS3204 is shipped with one AT-PWR3202 Power Supply
installed in slot A1, which can supply power for one switch. The AT-RPS3204
can accommodate up to three additional AT-PWR3202 Power Supplies,
supplying redundant power for a total of four Allied Telesis switches.

Caution: Air vents must not be blocked and must have free access to
room ambient air for cooling. 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.
