FAQ
How many devices can this switch power with PoE+?
The switch has a total PoE budget of 740 watts. Depending on the power requirements of each connected device (e.g., standard PoE devices use up to 15.4W, PoE+ up to 25.5W), it can support numerous powered devices simultaneously, such as a mix of IP phones, wireless access points, and security cameras, making it suitable for dense deployments.
What is the benefit of Layer 3 support in this switch?
Layer 3 support allows the switch to perform routing functions between different IP subnets or VLANs. This reduces the need for a separate router for internal traffic, improves network performance by keeping local traffic local, and enables more advanced network segmentation, security policies, and scalable network designs directly from the switch.
Can I use fiber optic connections with this switch?
Yes, the switch supports optical fiber connections through its four SFP (Small Form-factor Pluggable) slots. You can install compatible SFP transceivers to connect to fiber optic network cables, enabling high-speed 10 Gigabit Ethernet uplinks or connections over longer distances than standard copper Ethernet.
Is this switch manageable, and what management options are available?
Yes, this is a fully manageable switch. It can be configured and monitored using a command-line interface (CLI), a web-based graphical interface, and SNMP (Simple Network Management Protocol). This allows network administrators to set up VLANs, Quality of Service (QoS), security features, and monitor performance and status.
What rack space does this switch require for installation?
The switch is designed for standard 19-inch equipment racks and occupies 1 rack unit (1U) of vertical space. Its dimensions are 1.73 inches high, 17.42 inches wide, and 12.77 inches deep, making it a compact choice for data centers, server rooms, or wiring closets where space optimization is important.
What is the power consumption of this switch under normal operation?
The switch has a typical power consumption of 980 watts. This includes the power used by the switch itself plus the PoE power delivered to connected devices. The unit requires a standard AC power source and is designed for efficient operation in business environments with stable power infrastructure.
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?
