Product Description

The J9477A HP supports PoE+ modules, enabling power and data transmission over a single Ethernet cable to devices such as IP cameras and VoIP phones. It weighs 8 kg, facilitating easy installation and maintenance. This feature set makes it suitable for a variety of network infrastructure needs, ensuring efficient power management and connectivity.

Key Feature for the J9477A

  • What is PoE+?
    PoE+ stands for Power over Ethernet Plus, a technology that allows network cables to carry electrical power and data simultaneously to devices such as IP cameras and VoIP phones.
  • How much does the PoE+ module weigh?
    The PoE+ module weighs 8 kg.
  • Can the PoE+ module be used with any network switch?
    The PoE+ module is designed to be compatible with network switches that support the IEEE 802.3at standard. It's important to check your switch specifications for compatibility.
  • What is the part number for the PoE+ module weighing 8 kg?
    The specific part number for the module is not provided. Please refer to the product catalogue or contact customer support for this information.
  • What devices can be powered using a PoE+ module?
    Devices such as wireless access points, IP cameras, and VoIP phones can be powered using a PoE+ module, provided they are PoE or PoE+ compliant.
  • Is there a maximum distance for cable length when using the PoE+ module?
    Yes, the maximum cable length for effective power and data transmission over Ethernet using PoE+ is 100 meters (328 feet).
  • Can I use the PoE+ module in outdoor environments?
    While PoE+ modules are primarily designed for indoor use, outdoor use is possible with appropriate weatherproof enclosures and considerations for temperature and humidity.
  • What is the energy efficiency of the 8 kg PoE+ module?
    Energy efficiency can vary based on the specific model and manufacturer. It's best to refer to the technical specifications for the module's energy consumption and efficiency ratings.
  • How does PoE+ differ from standard PoE?
    PoE+ (IEEE 802.3at) provides up to 30 Watts per port, which is more power compared to standard PoE (IEEE 802.3af) that delivers up to 15.4 Watts per port. This enables support for devices that require more power to operate.
  • Can the PoE+ module support high-power devices like PTZ cameras?
    Yes, the PoE+ module can support high-power devices such as Pan-Tilt-Zoom (PTZ) cameras, given its higher power output compared to standard PoE. However, always verify the power requirements of the device to ensure compatibility.

Product Review

The HP J9477A supports PoE+ modules, catering to modern networking demands by enabling power supply to devices via Ethernet. However, its weight of 8 kg makes it less ideal for environments where frequent reconfiguration or mobility is required. This switch is well-suited for stable setups where its power capabilities are prioritized over portability.


The HP J9477A is a high-performance networking switch designed to cater to the needs of modern businesses requiring efficient, scalable, and secure networking solutions. This device stands out for its support for Power over Ethernet Plus (PoE+), which allows for both electrical power and data to be transmitted over a single Ethernet cable to connected devices like IP cameras and VoIP phones, simplifying the network infrastructure and reducing installation costs. Weighing 8 kg, the HP J9477A is engineered for durability and easy installation in various environments, from small office spaces to large data centers. Its compact form factor ensures that it can fit into tight spaces, optimizing rack space while providing the high-capacity network connectivity that today's businesses demand. Key hardware specifications of the HP J9477A include: - Power over Ethernet Plus (PoE+): This feature enables the switch to supply power to connected devices, such as wireless access points and surveillance cameras, through the Ethernet cable. It significantly reduces cabling requirements and costs, while also offering the flexibility to install devices in locations without immediate access to power outlets. - Scalability: The HP J9477A is designed to grow with your business. Its modular design allows for easy expansion, providing the option to increase port density or introduce new functionalities without the need for an entirely new device. This ensures that your investment is future-proof, adapting to changing network requirements with minimal additional cost. - Security: Understanding the importance of network security, the HP J9477A incorporates advanced security features to protect sensitive data from threats. These include access control lists (ACLs), which permit or deny traffic based on source and destination IP addresses, MAC addresses, or VLANs; port security, which limits the number of MAC addresses seen on a port to prevent unauthorized access; and secure management options, such as SSH and SNMPv3, to safeguard network management activities. The HP J9477A also offers exceptional performance and reliability. It supports high-speed data transfers, ensuring that network traffic flows efficiently without bottlenecks. This makes it suitable for data-intensive applications, including video conferencing, streaming, and cloud services. Furthermore, its robust thermal design ensures that the device operates reliably under various temperature conditions, maintaining optimal performance even in demanding environments. For network administrators, the HP J9477A provides comprehensive management options. It supports both web-based and command-line interface (CLI) management, allowing for flexible configuration and monitoring according to the administrator's preference. Real-time monitoring and diagnostic tools are also available, enabling quick identification and resolution of network issues, minimizing downtime. In conclusion, the HP J9477A is a versatile and efficient networking switch that meets the demands of modern businesses. Its support for PoE+, combined with scalability, advanced security features, and reliable performance, makes it an excellent investment for organizations looking to build or upgrade their network infrastructure. Whether deployed in a small office or a large data center, the HP J9477A provides the foundation for a high-performance, secure, and manageable network.
