Overview

The HP J9478A is a networking module designed to enhance connectivity and power delivery for businesses and enterprises. This module features 24 ports with PoE+ (Power over Ethernet Plus) capability, allowing for both data and power to be delivered over a single twisted pair cable. This design simplifies the network infrastructure by reducing the need for additional power supplies and wiring, making it an efficient solution for deploying devices like VoIP phones, wireless access points, and surveillance cameras. Each of the 24 ports on the HP J9478A supports 10/100 Base-TX connectivity, ensuring compatibility with a wide range of network devices while providing sufficient bandwidth for typical office and enterprise applications. The ports utilize RJ-45 connectors, a standard in networking that guarantees compatibility with a broad array of networking equipment. To ensure reliable performance, the module requires Category 5 or better 100-Ohm UTP or STP cables, a specification that ensures minimal signal degradation over distances and maintains the integrity of data transmission. The HP J9478A belongs to the zl module type, a classification that hints at its compatibility with HP's modular switch chassis. This allows for easy integration into existing network setups, providing a seamless upgrade path for expanding network capabilities or replacing outdated modules without the need for a complete system overhaul.
  • Minimum Operating Temperature: 0 °C, ensuring the module operates efficiently even in cold environments.
  • Maximum Operating Temperature: 40 °C, allowing for deployment in various conditions without the risk of overheating.
  • Maximum Operating Altitude: 10,000 ft, enabling installation in high-altitude locations without affecting performance.
For environments not actively using the module, it has a wide range of non-operating temperature tolerance, from -40 °C to 70 °C, ensuring that the module remains undamaged in storage conditions that may experience extreme temperatures. The device is also designed to withstand non-operating relative humidity levels from 15% to 95% non-condensing, and up to 90% for operating conditions, making it suitable for use in a variety of climates without concern for moisture-induced damage. Additionally, the HP J9478A can be installed in locations up to 15,000 ft in altitude without operational concerns when not in use, providing flexibility in storage options for organizations located in or near mountainous regions. In summary, the HP J9478A is a versatile and efficient networking module that simplifies infrastructure, supports high-speed connectivity, and is resilient under a variety of environmental conditions. Its design and specifications ensure that it can meet the needs of modern businesses looking to maintain or expand their networking capabilities with minimal disruption and maximum reliability.
