    The device can operate at altitudes up to 3 km (10,000 ft).
  • How many power supply slots does the device have, and what is required for operation?
    There are 2 power supply slots, with a minimum of one power supply required for operation.
  • What is the frequency range supported by the device's power supply?
    The power supply supports a frequency range of 50/60 Hz.
  • Are there any specific conditions under which the device's maximum temperature should not exceed 45°C?
    Yes, the maximum temperature should not exceed 45°C when transceivers are installed.
  • What are the supported standards for the RJ-45 autosensing ports?
    The RJ-45 autosensing ports support IEEE 802.3 Type 10BASE-T, IEEE 802.3u Type 100BASE-TX, IEEE 802.3ab Type 1000BASE-T, and IEEE 802.3at PoE+ standards.

Product Review

The HP J9575A switch offers a versatile range of connectivity options, including 24 RJ-45 autosensing ports that support up to 1000BASE-T speeds and PoE+, along with two fixed 1000/10000 SFP+ ports for high-speed uplinks. However, its reliance on a single included power supply, despite having slots for two, could pose a risk for redundancy and uptime in mission-critical environments. Additionally, its operating temperature range limits to 45°C when transceivers are installed, which might restrict deployment in high-temperature settings, potentially affecting its suitability for certain operational scenarios.


The HP J9575A is a networking switch designed to accommodate the needs of modern businesses requiring high-speed connectivity and reliable network performance. This switch features 24 RJ-45 autosensing ports that support 10/100/1000 Mbps connections and comply with IEEE standards such as 802.3 for 10BASE-T, 802.3u for 100BASE-TX, 802.3ab for 1000BASE-T, and 802.3at for Power over Ethernet Plus (PoE+), ensuring compatibility with a wide range of network devices. The 1000BASE-T ports operate at full duplex only, maximizing data transfer rates and network efficiency. Additionally, the switch includes two fixed SFP+ ports that support 1000/10000 Mbps for high-speed connectivity and uplink capabilities. A dedicated RJ-45 serial console port is available for local management, along with an RJ-45 out-of-band management port for remote network management. The inclusion of a stacking module slot allows for the scalable integration of multiple units, enhancing network capacity and flexibility.
