4. Seadistamine ja installimine

4.1 Riiuli paigaldamine

1. Identify a 1U (1.75 inches) space in your standard 19-inch server rack.
2. Attach the provided mounting brackets to the sides of the PDU using the included screws.
3. Secure the PDU into the rack using appropriate rack screws, ensuring it is firmly seated.

4.2 Toiteühendus

1. Connect the IEC-320 C20 input connector of the PDU to a compatible 208V-230V, 16A power source. Ensure the power source is properly grounded and capable of supplying the required current.
2. Connect your IT equipment's power cords to the eight (8) C13 output receptacles on the PDU. Distribute the load evenly across the outlets if possible.

5. Operatsioon

5.1 Sisselülitamine

Once the PDU is connected to a power source, it will power on automatically. The local current monitoring display will illuminate, showing the total current draw.

5.2 Local Current Monitoring

The integrated display on the front panel provides real-time information on the total current being drawn by all connected devices. This helps in preventing overloads and managing power capacity.

5.3 Remote Individual Outlet Control

The AP7921 allows for remote control of each individual C13 outlet. This feature enables users to power cycle, turn on, or turn off connected equipment remotely, which is beneficial for troubleshooting or managing power to specific devices without physical access.

5.4 Power Delays

The PDU supports configurable power-on and power-off delays for its outlets. This feature helps in sequencing the startup of equipment to prevent inrush current overloads and manage system dependencies.

6. Konfiguratsioon

The AP7921 PDU offers various configuration options through its network interface for remote management.

6.1 Võrgujuurdepääs

Connect the PDU to your network using an Ethernet cable. Access the PDU's web interface via its assigned IP address to configure settings, monitor status, and control outlets. Refer to the network configuration guide for initial setup.

6.2 Häire läved

Configure alarm thresholds for current draw. The PDU can send alerts via email or SNMP traps if the current exceeds or falls below specified limits, helping to prevent overloads or identify power issues.

6.3 Püsivara värskendused

The PDU's firmware is flash upgradeable. Regularly check the APC website for the latest firmware versions to ensure optimal performance and access to new features. Follow the provided instructions for firmware upgrade procedures.

7. Hooldus

7.1 Puhastamine

Periodically clean the exterior of the PDU with a soft, dry cloth. Do not use liquid cleaners or solvents. Ensure the PDU is disconnected from the power source before cleaning.

7.2 Keskkonnakaalutlused

Ensure the PDU operates within its specified temperature and humidity ranges. Maintain proper airflow around the unit to prevent overheating.

8. Veaotsing

8.1 No Power to Outlets

• Verify the input power cable is securely connected to both the PDU and the power source.
• Check the circuit breaker on the PDU (if present) and the upstream circuit breaker.
• Ensure individual outlets are not remotely switched off.

8.2 Overload Indication

• If the local display or remote interface indicates an overload, immediately disconnect non-essential equipment.
• Reduce the total load to below the PDU's maximum rated current (16A).
• Check for short circuits in connected equipment.

8.3 Kaugjuurdepääsu probleemid

• Verify network cable connection and network status.
• Confirm the PDU's IP address and network settings.
• Ensure firewall rules are not blocking access to the PDU's management interface.
