Intel AXX750WPS 750W Hot-Plug Redundant Power Supply User Manual

1. Introduction

This manual provides essential information for the safe and efficient use of your Intel AXX750WPS 750W Hot-Plug Redundant Power Supply. This power supply module is designed for use in compatible server systems, offering reliable power delivery and redundancy for critical applications. Please read this manual thoroughly before installation and operation.

2. Safety Information

Always observe the following safety precautions to prevent injury and damage to the equipment:

• Electrical Hazard: This product operates with high voltage. Only qualified personnel should perform installation and maintenance.
• Grounding: Ensure the server chassis is properly grounded before installing or removing the power supply.
• Hot-Plug Safety: While designed for hot-plugging, always follow the server manufacturer's guidelines for hot-swapping components to avoid system disruption.
• Ventilation: Do not block ventilation openings on the power supply or server. Adequate airflow is crucial for proper cooling.
• Moisture: Keep the power supply away from liquids and excessive humidity.
• Static Discharge: Use anti-static precautions (e.g., wrist strap) when handling the power supply to prevent damage from electrostatic discharge.

3. Package Contents

Verify that your package contains the following items:

4. Product Overview

The Intel AXX750WPS is a 750-watt hot-plug power supply module designed for server environments requiring high availability and efficient power delivery. Its key features include:

• 750 Watt Output: Provides ample power for demanding server configurations.
• Hot-Plug Capability: Allows for replacement or installation without powering down the server, minimizing downtime.
• Redundant Design: Supports N+1 or N+N redundancy configurations when used with multiple identical power supplies in a compatible server chassis.
• Power Factor Correction (PFC): Improves power efficiency and reduces energy waste.
• Air Cooling: Integrated fan for effective heat dissipation.

5. Setup and Installation

Before proceeding with installation, ensure your server system is compatible with the Intel AXX750WPS power supply module and has an available power supply bay.

5.1 Pre-installation Checks

1. Verify that the server is powered off or in a state that supports hot-swapping, as per the server manufacturer's instructions.
2. Ensure you have an anti-static wrist strap connected to a grounded surface.
3. Confirm that the power supply bay is clear of obstructions.

5.2 Installation Steps

1. Carefully unpack the new Intel AXX750WPS power supply module.
2. If replacing an existing power supply, unlatch and pull the handle to slide the old module out of the bay.
3. Align the new power supply module with the empty bay in the server chassis.
4. Gently slide the module into the bay until it is fully seated and the latch mechanism engages. You should feel a click or resistance indicating it's properly connected.
5. Connect the AC power cord to the power supply module and then to a grounded power outlet or PDU.
6. Observe the status indicator lights on the power supply (refer to Section 6.2 for details).

6. Operating Instructions

6.1 Powering On/Off

Once the power supply is installed and connected to an AC source, it will typically power on automatically if the server is already running or when the server is powered on. For redundant configurations, individual power supplies can be removed and inserted while the system is operational.

6.2 Status Indicators

The Intel AXX750WPS typically features LED indicators to communicate its operational status. Common indicators include:

• Green/Amber LED: A solid green light usually indicates normal operation and power output. An amber or flashing light may indicate a fault or a non-redundant state.
• Refer to your server's documentation for specific interpretations of power supply LED patterns, as these can vary by system.

6.3 Redundancy Operation

In a redundant configuration (e.g., two AXX750WPS modules in a server designed for N+1 redundancy), if one power supply fails, the other(s) will automatically take over the full load, ensuring continuous operation. The failed module can then be hot-swapped for a new one without interrupting server uptime.

7. Maintenance

The Intel AXX750WPS power supply is designed for minimal maintenance. However, periodic checks can help ensure optimal performance and longevity.

• Dust Removal: Periodically inspect the power supply and server ventilation areas for dust accumulation. Use compressed air to gently clear dust from vents and fan grilles. Ensure the server is powered down and unplugged if removing the power supply for cleaning.
• Cable Inspection: Check AC power cords for any signs of damage, fraying, or loose connections. Replace damaged cables immediately.
• Environmental Conditions: Ensure the server environment maintains appropriate temperature and humidity levels as specified by the server manufacturer.

8. Troubleshooting

If you encounter issues with your Intel AXX750WPS power supply, consider the following troubleshooting steps:
