Product Review

The HP JL322A switch boasts a flexible array of I/O ports, including 44 autosensing 10/100/1000 ports and 4 combo PoE+ or SFP ports, catering to a broad range of networking needs. However, it lacks redundant power supplies, a potential drawback for environments requiring uninterrupted service. With support for PoE power up to 1440 Watts and efficient heat dissipation, it is suitable for high-power devices and operations, but the absence of included power supplies may increase initial setup costs.


The HP JL322A is a networking switch designed to accommodate the diverse needs of modern businesses, featuring a comprehensive array of I/O ports and slots to ensure flexibility and scalability in network deployment. This device includes 44 autosensing 10/100/1000 ports supporting various IEEE standards such as 10BASE-T, 100BASE-TX, and 1000Base-T, with PoE+ capabilities on IEEE 802.3at, facilitating both power and data transmission over a single cable to devices such as IP cameras and VoIP phones. The duplex settings are configured to support half or full for 10BASE-T/100BASE-TX and full only for 1000BASE-T connections, optimizing data flow and minimizing packet loss. In addition to these, the HP JL322A offers: - 4 Combo 10/100/1000BASE-T PoE+ or 100/1000Mbps SFP Ports for enhanced connectivity and uplink flexibility. - 1 Dual Personality (RJ-45 or USB Micro-B) serial console port for versatile management options. - 1 USB A port for easy upload/download of files, aiding in quick configuration and firmware updates. Moreover, the switch is equipped with a 100BASE-T Out of Band Management Port, an Uplink Slot, a Stacking Module Slot, and two Power Supply Slots (power supplies sold separately), enhancing its functionality and adaptability in complex network setups. The physical dimensions of the JL322A are compact, with a height of 1.73 inches (4.39 cm), a width of 17.42 inches (44.25 cm), and a depth of 12.77 inches (32.43 cm), making it suitable for rack mounting in standard 19-inch racks. Despite its substantial capabilities, the switch maintains a manageable weight of 10.25 lbs (4.65 kg), facilitating easy installation and reconfiguration as needed. Environmentally, the switch is designed to operate reliably in a range of conditions. It supports an operating temperature from 32°F to 131°F (0°C to 55°C) up to 5000ft, with a slight deration above this altitude. The operating relative humidity range is 15% to 95% (non-condensing), and the device can withstand non-operating/storage temperatures from -40°C to +70°C up to 15000 ft, with a non-operating/storage relative humidity of up to 90% at 65°C (non-condensing). From an acoustic standpoint, the JL322A operates quietly with a sound power level of 4.6 Bel and a bystander sound pressure level of 28.9 dB, minimizing noise in work environments. The primary airflow direction from port to power ensures efficient cooling, crucial for maintaining optimal performance. The switch's power specifications reveal a maximum heat dissipation of 355 BTU/hr (375 kJ/hr), with various voltage and current ratings depending on the power supply unit model. The idle power consumption is 73W, and it can deliver up to 1440 Watts of PoE power, highlighting its efficiency and capability to support a wide range of PoE devices.
