5. Setup
5.1 Physical Installation
The SMT750RM2UC is a 2U rackmount unit. Ensure proper ventilation and secure mounting within a standard 19-inch rack.
Step 1: Install the rackmount rails (if not pre-installed) into your server rack according to the rail manufacturer's instructions.
Step 2: Carefully slide the UPS unit onto the installed rails until it clicks into place. Secure the front of the UPS to the rack using the provided screws.
Step 3: Ensure adequate clearance for airflow around the front and rear of the unit.
5.2 Connections
Connect your equipment to the UPS as follows:
- Input Power: Connect the UPS input power cord (NEMA 5-15P) to a grounded utility power outlet.
- Output Connections: Connect your critical equipment (servers, network devices, etc.) to the 6 x NEMA 5-15R output receptacles on the rear of the UPS.
- Communication Ports:
- USB Port: Connect the provided USB cable from the UPS to your computer for local monitoring and graceful shutdown via PowerChute software.
- Serial Port: Connect the provided serial cable for local monitoring and graceful shutdown via PowerChute software.
- SmartConnect Ethernet Port: Connect an Ethernet cable to this port for cloud-based remote monitoring and management.
- SmartSlot: An optional slot for installing accessories like a Network Management Card for advanced network-based management.
5.3 Initial Power On
After all connections are made:
- Press the power button on the front panel of the UPS.
- The LCD display will illuminate, and the UPS will perform a self-test.
- Allow the UPS to charge its batteries for at least 24 hours before relying on it for extended backup power.
6. Operation
6.1 LCD Display and Control
The front panel LCD provides real-time status information and allows for configuration of UPS settings. Use the navigation buttons (Esc, Up, Down, Enter) to browse menus and adjust parameters.
- Status Indicators: Display battery charge, load level, and operational mode.
- Configuration: Adjust output voltage, sensitivity, alarm settings, and more.
- Self-Test: Initiate a battery self-test to check battery health.
6.2 Automatic Voltage Regulation (AVR)
The UPS automatically corrects minor voltage fluctuations (sags and surges) without switching to battery power, preserving battery life and ensuring a stable power supply to connected equipment.
6.3 SmartConnect Port
The SmartConnect port enables cloud-based monitoring of your UPS. Once connected to your network and registered, you can access UPS status, receive alerts, and perform basic management tasks from a web browser or mobile app.
6.4 Graceful Shutdown
In the event of an extended power outage, the UPS can initiate a graceful shutdown of connected servers and virtual machines using PowerChute software (via USB or Serial) or an optional Network Management Card (via SmartSlot). This prevents data loss and ensures system integrity.
7. Maintenance
7.1 Battery Care and Replacement
The UPS contains a sealed, maintenance-free lead-acid battery. Batteries typically last 3-5 years under normal operating conditions. Replace batteries when the UPS indicates a battery fault or when runtime significantly decreases.
- Refer to the full user manual for detailed battery replacement instructions.
- Always use genuine APC replacement battery cartridges (RBCs) to ensure compatibility and optimal performance.
- Recycle old batteries responsibly.
7.2 Cleaning
Periodically clean the exterior of the UPS with a soft, damp cloth. Ensure ventilation openings are free from dust and debris to maintain proper airflow.
8. Troubleshooting
