1 RPS Description and Specifications Overview Thank you for choosing the RPS900W redundant power supply (RPS). This RPS is built to provide a reliable redundant power source for Edge-Core ECS4510-52P and ECS4620-52P PoE-enabled switches that are equipped with a redundant DC power input connector. In the event of an AC power outage or failure of the switch’s internal power supply, this RPS can supply up to 900 Watts of backup power for your PoE switch.
Chapter 1 | RPS Description and Specifications Key Hardware Components ◆ The RPS will operate under a no-load condition. Key Hardware Components Two status indicators, SYS and PoE LEDs, are located on the RPU’s front panel. While the AC input socket, grounding point, and DC output connector are located on the RPU’s rear panel. Figure 1: Front Panel 1 1 2 SYS LED 2 PoE LED SYS and PoE LEDs For information on the SYS and PoE LED indicators, see “Understanding the SYS and PoE LEDs” on page 23.
Chapter 1 | RPS Description and Specifications Key Hardware Components AC Input Socket The RPS requires a 100-240 VAC, 50-60 Hz AC power source. For more information on the RPS power input, how to connect it, and how to power-on the RPS, see “Connecting the RPS to a Switch and AC Power Source” on page 21. 25-Pin DC Output Connector The female DB-25 connector on the rear of the RPS provides dual DC voltage supplies over the included DC power cable to the connected switch.
Chapter 1 | RPS Description and Specifications Key Technical Specifications Key Technical Specifications The following table contains key system specifications for the RPS. Table 1: Key Technical Specifications Item Specification Ports Single Female DB-25 DC Output Port LEDs Sys, PoE Weight 3.9 kg (8.6 lb) Size (W x D x H): 18.00 x 16.50 x 3.75 cm (7.09 x 6.50 x 1.
2 Installing the RPS The RPS is designed to be installed in a standard 19-inch equipment rack. Before continuing with the RPS installation, first review the general guidelines and RPS cooling requirements in this chapter.
Chapter 2 | Installing the RPS Package Contents Package Contents After unpacking the RPS, check the contents to be sure you have received all the components. ◆ RPS900W Redundant Power Supply ◆ Rack Mounting Kit — Contains two mounting brackets and eight screws for attaching the brackets to the RPS. ◆ Four adhesive foot pads ◆ AC power cord ◆ DC power cable — 1 m (3.
Chapter 2 | Installing the RPS How to Install the RPS in a Rack How to Install the RPS in a Rack When rack mounting the RPS, pay particular attention to the following factors: ◆ Rack Types: You can use any standard EIA 19-inch equipment rack with either two or four posts. The bracket hole pattern should be spaced 1U (1.75 in. or 4.45 cm) apart. ◆ Rack Stability: Whenever possible, secure the rack to the building ceiling or floor, particularly if you are located in a region where earthquakes are common.
Chapter 2 | Installing the RPS How to Install the RPS in a Rack Rack-Mount Procedure To rack mount the RPS, follow these steps: 1. Attach the brackets to the RPS using the screws provided in the Rack Mounting Kit. Figure 4: Attaching the Extension Brackets 2 1 1 Rack Mounting Bracket 2 Bracket Screws 2. Following your rack plan, mark the holes in the rack where the RPS will be installed. 3. Lift the RPS into the rack so that it is aligned with the marked holes. 4.
Chapter 2 | Installing the RPS How to Install the RPS on a Shelf or Desktop Figure 5: Installing the RPS in a Rack 1 1 Rack Mounting Screws 5. Go to “Grounding the Chassis” on page 20. How to Install the RPS on a Shelf or Desktop The RPS can be installed on any flat surface such as a desktop or shelf. To mount the RPS on a flat surface, follow these steps: 1. Attach the four adhesive feet to the bottom of the first RPS.
Chapter 2 | Installing the RPS RPS Cooling Requirements Figure 6: Attaching the Adhesive Feet 1 1 Adhesive foot pad 2. Set the device on a flat surface near an AC power source and near enough to the switch so that the DC power cable will reach. Make sure there are at least two inches of space on all sides for proper airflow. 3. Go to “Grounding the Chassis” on page 20. RPS Cooling Requirements Wherever the RPS is located, be sure to pay close attention to RPS cooling requirements.
Chapter 2 | Installing the RPS RPS Cooling Requirements Figure 7: RPS Cooling 1 2 1 Warm Air 2 Cool Air Rack Cooling When mounting the RPS in an enclosed rack or cabinet, be sure to check the following guidelines to prevent overheating: ◆ Make sure that enough cool air can flow into the enclosure for the equipment it contains. The RPS requires 14 CFM of cooling air flow.
Chapter 2 | Installing the RPS Grounding the Chassis Grounding the Chassis The rear panel of the RPS chassis includes a dual-screw grounding terminal. It must be connected to ground to ensure proper operation and to meet electromagnetic interference (EMI) and safety requirements. Figure 8: Grounding Terminal 1 2 1 2 Grounding Wire Dual-Screw Grounding Terminal Before connecting AC power to the RPS, ground the RPS to earth as described below. 1.
Chapter 2 | Installing the RPS Connecting the RPS to a Switch and AC Power Source Caution: The earth connection must not be removed unless all supply connections have been disconnected. 6. Go to “Connecting the RPS to a Switch and AC Power Source” on page 21. Connecting the RPS to a Switch and AC Power Source The RPS is shipped with a custom DC power cable that you must use to connect the RPS to a switch.
Chapter 2 | Installing the RPS Connecting the RPS to a Switch and AC Power Source 2. Connect the DB-25 male end to the DC output connector on the RPS. 3. Connect one end of the AC cord to the AC socket on the RPS, and the other end to a grounded power outlet. Caution: The RPS requires power from an external AC power supply that can meet the required specification described in Table 2. A standard AC power socket is located on the rear panel of the RPS. The power socket is for the AC power cord.
Chapter 2 | Installing the RPS Understanding the SYS and PoE LEDs Table 2: AC Power Supply Specifications Item Description AC Input AC 100-240 V, 50-60 Hz, 12 A @ 100 VAC, 6 A @ 240 VAC Power Supply 100-240 VAC, 50-60 Hz, auto-sensing Maximum Power Output 11.3 VDC: 126 W 53.8 VDC: 780 W 4. Check the LEDs on the RPU to ensure that the DC voltages being supplied to the switch are correct. If not, recheck the power cord connections at the AC supply source and back panel power input connector.
Chapter 2 | Installing the RPS Understanding the SYS and PoE LEDs Table 3: SYS and PoE LEDs LED Condition Status SYS On Green The RPS 11.3 VDC output voltage is within specifications. Off The RPS 11.3 VDC output voltage is outside specifications or has failed. On Green The RPS 53.8 VDC output voltage is within specifications. Off The RPS 53.8 VDC output voltage is outside specifications or has failed.
A Troubleshooting Diagnosing LED Indicators Table 1: Troubleshooting Chart Symptom Action Sys LED is Off ◆ ◆ ◆ PoE LED is Off ◆ ◆ ◆ Confirm the DC power cable is installed correctly and there is no apparent damage to it; if so, replace it. Confirm the AC power source is within the specified requirements; if not, connect the RPS to another AC power outlet which provides the correct power specification. If the condition does not clear, contact your dealer for assistance.
