Description
The HP J9574A ProCurve 3800 48-Port PoE+ 4-SFP+ Gigabit Switch delivers 48 autosensing 10/100/1000 RJ-45 ports with PoE+ support, making it well suited for connecting VoIP phones, wireless access points, security devices, and other powered Ethernet equipment. HPE identifies the J9574A as the E3800-48G-PoE+-4SFP+ model in the 3800 switch family. In addition to its copper access ports, the switch includes 4 fixed 1000/10000 SFP+ uplink ports for high-speed fiber or DAC uplink connectivity. That makes it a practical choice for organizations that need both dense Gigabit edge access and 10GbE bandwidth for uplinks to distribution or core switches. The 3800 series is positioned by HPE as a fully managed advanced Layer 3 switch family with meshed stacking technology, giving the platform appeal for enterprise environments that need resiliency, scalability, and strong feature depth. The J9574A also supports IEEE 802.3at PoE+ operation with up to 30 watts per port on supported devices.

We installed the HP J9574A in our network and it has been a very solid switch. The 48 PoE+ ports gave us plenty of capacity for phones and access points, and the 10GbE SFP+ uplinks were a big help for improving backbone connectivity. Setup was straightforward and overall we have been very happy with its performance.
