5. Setup

Follow these steps to install the AC Power Supply into the MX2800 chassis:

1. Power Off: Ensure the MX2800 chassis is completely powered off and disconnected from all power sources.
2. Locate Slot: Identify the designated power supply slot(s) in the MX2800 chassis. Refer to the MX2800 chassis manual for specific slot locations.
3. Insert Power Supply: Carefully slide the AC Power Supply into the vacant slot until it is fully seated. Ensure the connectors align properly.
4. Secure Unit: Use any provided thumbscrews or locking mechanisms to secure the power supply in place within the chassis.
5. Connect AC Power: Connect a suitable AC power cord (not included) to the power supply's AC inlet and then to a grounded electrical outlet.
6. Power On: Reconnect power to the MX2800 chassis and power it on. Observe the power supply's indicator lights for proper operation.

6. Operating Instructions

Once installed and powered on, the redundant AC power supply operates automatically. Key operational aspects include:

• Power Indicators: Check the status indicator lights on the power supply. A solid green light typically indicates normal operation. Refer to the MX2800 chassis manual for specific indicator meanings.
• Redundancy: If two power supplies are installed, they operate in a redundant configuration. Should one unit fail, the other automatically takes over, ensuring continuous operation of the MX2800.
• Hot-Swappable: This power supply is designed to be hot-swappable, meaning it can be replaced without powering down the entire MX2800 chassis, provided another operational power supply is present. Always follow proper hot-swap procedures outlined in the MX2800 chassis manual.

7. Maintenance

The ADTRAN MX2800 AC Power Supply requires minimal maintenance. Regular checks can help ensure its longevity and reliable performance:

• Visual Inspection: Periodically inspect the power supply and its connections for any signs of damage, loose cables, or excessive dust accumulation.
• Cleaning: If dust is present, gently clean the exterior of the power supply and the chassis ventilation openings using a soft, dry cloth or compressed air. Ensure the unit is powered off and disconnected before cleaning.
• Firmware: Power supplies typically do not have user-upgradable firmware. Any firmware updates would be part of the main MX2800 chassis system.

8. Troubleshooting

If you encounter issues with your power supply, consider the following:

• No Power/No Indicators:
  • Verify the AC power cord is securely connected to both the power supply and a working electrical outlet.
  • Check the circuit breaker or fuse for the electrical outlet.
  • Ensure the power supply is fully seated in its slot within the MX2800 chassis.
• Fault Indicator Light:
  • A fault indicator (often amber or red) suggests an internal issue or an environmental problem.
  • If redundant power supplies are installed, the system should continue operating on the healthy unit.
  • Attempt to reseat the power supply. If the fault persists, the unit may require replacement.
• System Instability:
  • If the MX2800 system experiences unexpected shutdowns or instability, and a power supply fault is indicated, replace the faulty power supply.
  • Ensure the power supply is compatible with your specific MX2800 chassis model.
