User Manual
FAQ
How many devices can this switch power with PoE?
The switch has a total PoE budget of 370 watts, which can be allocated across its 48 PoE+ ports. Each port can deliver the IEEE 802.3at standard maximum of 30W. The actual number of powered devices depends on their individual power requirements; for example, it could power approximately 12 typical 802.11ac access points (each drawing ~30W) or a larger number of lower-power devices like VoIP phones.
What are the SFP+ uplink ports used for?
The four SFP+ ports provide 10 Gigabit Ethernet connectivity, which is up to 10 times faster than standard Gigabit. They are designed for high-bandwidth uplinks to core switches, servers, network-attached storage, or internet gateways. You can use them with compatible SFP+ transceivers for fiber optic cabling to cover longer distances or with direct-attach copper cables for short-range, cost-effective connections within a rack.
Is this switch manageable, and what features does it support?
Yes, this is a smart managed Layer 2 switch. It offers a web-based management interface for configuring VLANs to segment network traffic, Quality of Service (QoS) to prioritize voice or video traffic, port mirroring for network monitoring, and link aggregation to combine multiple ports for higher bandwidth. It also supports security features like IEEE 802.1x for network access control and IGMP snooping for efficient multicast handling.
Can this switch be mounted in a server rack?
Absolutely. The switch is designed for standard 19-inch server racks and occupies 1 rack unit (1U) of vertical space. It includes the necessary mounting brackets for secure installation. Its compact depth of 12.70 inches allows it to fit in most rack cabinets, and the front-to-back airflow design is compatible with typical rack cooling configurations.
What type of cabling does this switch support?
The 48 RJ-45 ports support standard twisted-pair Ethernet cabling (Cat5e, Cat6, or higher) for distances up to 100 meters. The four SFP+ uplink ports support optical fiber cabling via SFP+ transceivers for much longer distances (up to kilometers depending on the transceiver) or twinaxial copper cables for short-range connections within a data center or wiring closet.
What is the power consumption and input voltage requirement?
The switch has a maximum power consumption of 520 watts, which includes both the switch's own operation and the power delivered to PoE devices. It accepts a wide input voltage range of 100-240V AC, automatically adjusting to common North American (120V) and international (230V) power standards, making it suitable for global deployment without needing a voltage converter.
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.
