4. Setup
Rack Mounting:
The SMT2200RM2U is designed for installation in a standard 19-inch equipment rack, occupying 2U of rack space. Ensure the rack is stable and capable of supporting the UPS's weight (approximately 110.7 pounds). Follow the rack manufacturer's instructions for proper mounting.
Connections:
- Connect Input Power: Plug the UPS's input power cord into a dedicated, grounded 120V AC outlet.
- Connect Equipment: Plug your critical equipment into the NEMA 5-15R and NEMA 5-20R outlets on the rear panel of the UPS. Distribute the load evenly across the available outlets.
- Communication Connections: Connect the provided USB or serial cable from the UPS to your server for power management software communication. Install an optional network management card into the SmartSlot for remote monitoring and control.
- Initial Battery Charge: Allow the UPS to charge for at least 24 hours before connecting critical loads to ensure full battery capacity.
5. Operation
Power On/Off:
- To Power On: Press and hold the power button on the front panel until the LCD display illuminates.
- To Power Off: Press and hold the power button until the UPS powers down. For a graceful shutdown of connected equipment, use the power management software.
LCD Display and Controls:
The interactive LCD display provides comprehensive information about the UPS status and allows for various settings adjustments. Use the navigation buttons (up, down, enter, escape) to scroll through menus and select options.
The display typically shows:
- Input/Output Voltage and Frequency
- Battery Capacity and Charge State
- Load Percentage and Power (Watts/VA)
- Estimated Runtime on Battery
- Operating Mode (On Utility, On Battery, Green Mode)
- Efficiency
- Self-Test Results
Automatic Voltage Regulation (AVR):
The UPS features Automatic Voltage Regulation (AVR) to correct minor voltage fluctuations (sags and surges) without switching to battery power. This preserves battery life and ensures a stable power supply to your connected equipment.
6. Maintenance
Battery Replacement:
The SMT2200RM2U is equipped with hot-swappable batteries, allowing for replacement without powering down connected equipment. Refer to the specific battery replacement instructions provided with your replacement battery kit (e.g., RBC133). Always use genuine APC replacement batteries.
Cleaning:
Periodically clean the exterior of the UPS with a dry cloth. Ensure ventilation openings are free from dust and debris to maintain proper airflow and cooling.
7. Troubleshooting
If you encounter issues with your UPS, consult the LCD display for error messages or status indicators. Common issues and basic troubleshooting steps include:
- UPS not turning on: Check the input power connection and ensure the battery is properly connected and charged.
- Short runtime on battery: The battery may be old or not fully charged. Perform a battery self-test or consider battery replacement.
- Overload alarm: Reduce the load connected to the UPS. Ensure the total power consumption of connected devices does not exceed the UPS's capacity (1980W).
- No communication with software: Verify USB/serial cable connections and ensure the network management card (if installed) is properly configured and connected to the network.
For more detailed troubleshooting, refer to the comprehensive user manual available on the APC website or contact APC technical support.
