User Manual
FAQ
How many devices can this switch power with PoE?
The switch has a 370-watt PoE budget distributed across its 48 Gigabit Ethernet ports. Each port supports the IEEE 802.3at (PoE+) standard, delivering up to 30 watts per port. This allows it to power numerous devices like IP phones, wireless access points, and security cameras simultaneously, with the exact number depending on the individual power requirements of each connected device.
What are the SFP+ uplink ports used for?
The four SFP+ uplink ports provide high-speed connectivity for linking this switch to core network switches, servers, or storage arrays. They support both 1 Gigabit and 10 Gigabit speeds using compatible SFP+ transceivers for fiber optic cables or Direct Attach Copper (DAC) cables. This enables scalable bandwidth aggregation and reduces bottlenecks in your network backbone.
Is this switch easy to manage for someone without deep networking experience?
Yes, as a smart managed switch, it offers a web-based interface that simplifies configuration of essential features like VLANs, Quality of Service (QoS), port monitoring, and PoE management. It provides more control than an unmanaged switch but avoids the complexity of CLI-based fully managed switches, making it suitable for IT generalists or small business owners.
Can this switch be mounted in a standard server rack?
Absolutely. The switch is designed for standard 1U rack mounting, with dimensions that fit typical 19-inch server racks. It includes the necessary mounting brackets.
