User Manual
FAQ
How many devices can this switch power with PoE?
The switch has a total PoE budget of 370 watts, which it can allocate across its 48 PoE+ ports. The exact number of devices depends on their individual power requirements. For example, it could power approximately 24 typical VoIP phones (each using ~7W) or 12 standard wireless access points (each using ~30W), or a mix of various PoE devices like cameras, phones, and APs. The smart management interface allows you to monitor power usage per port.
What are the SFP+ uplink ports used for?
The four SFP+ ports are high-speed 10 Gigabit Ethernet uplinks. They are used to connect the switch to other network equipment like core switches, routers, or servers at much higher speeds than the standard Gigabit ports. This prevents bottlenecks in your network backbone. You can use SFP+ optical transceivers for fiber connections over long distances or SFP+ direct-attach copper cables for short-range, high-bandwidth links within a rack.
Is this a managed switch, and what features does it include?
Yes, this is a smart managed Layer 2 switch. It provides web-based management for configuration without the complexity of a full CLI. Key features include VLAN support (IEEE 802.1Q) for network segmentation, Quality of Service (QoS via IEEE 802.1p) to prioritize voice or video traffic, port mirroring for monitoring, IGMP snooping for efficient multicast streaming, and spanning tree protocols for network loop prevention. It also supports IEEE 802.1x for network access control.
Can this switch be mounted in a standard server rack?
Absolutely. The switch is designed for 1U rack mounting and includes the necessary hardware. Its dimensions are 1.73 inches high, 17.42 inches wide, and 12.70 inches deep, which is a standard form factor for 19-inch wide equipment racks. For non-rack environments, it also supports flexible mounting options including wall, tabletop, cabinet, or under-table installation.
What is the difference between PoE and PoE+ on this switch?
All 48 RJ-45 ports on this switch support both PoE (IEEE 802.3af, up to 15.4W per port) and PoE+ (IEEE 802.3at, up to 30W per port). PoE+ delivers more power, which is necessary for devices like higher-end wireless access points, pan-tilt-zoom cameras, or thin clients. The switch automatically detects the power requirement of each connected device and supplies the appropriate level, up to the 370W total system budget.
What kind of cables and media does this switch support?
For the 48 Gigabit RJ-45 ports, it supports standard twisted-pair Ethernet cables (Cat5e, Cat6, or higher) for distances up to 100 meters. The network technology is 10/100/1000Base-T. For the four SFP+ uplink ports, you can use either optical fiber cables (with compatible SFP+ transceivers) for long-distance runs or twinaxial copper cables (SFP+ DAC) for short connections within a rack. The switch supports both media types, giving you flexibility in backbone design.
What uplink, SFP, fiber, or media support detail is listed?
The warranty or support detail listed is Yes, giving buyers a clearer picture of expected coverage after purchase.
Does the product support PoE or wireless networking?
Connectivity support is listed in the product specifications, including the relevant wireless or port options when available.
