❓ Frequently Asked Questions (FAQ)
🔌 What is Power over Ethernet (PoE+) and what is its use?
PoE+ (IEEE 802.3at) allows you to power your network devices directly via the Ethernet cable, up to 30W per port. This Cisco SG350-28P switch has 24 PoE+ ports with a total budget of 195W, ideal for powering VoIP phones, IP surveillance cameras, wireless WiFi access points, or access controllers. This way, you save on power adapters and significantly simplify your professional network installation.
🌐 What is the difference between a Layer 2 switch and a Layer 3 switch?
A Layer 3 switch like the SG350-28P integrates advanced IP routing features in addition to classic Layer 2 switching. It can create static routes between different VLAN subnets, manage inter-VLAN routing at hardware speed, and support up to 128 IP interfaces. It's perfect for segmenting your enterprise network infrastructure into multiple VLANs while maintaining fast communications between them, without requiring a dedicated external router.
📡 What are the combo and SFP ports for?
This Cisco switch has 2 combo ports (RJ-45 Gigabit + SFP) and 2 dedicated SFP ports. The combo ports allow the use of either a standard copper Ethernet cable or an SFP module for fiber optics. SFP modules (Small Form-factor Pluggable) support single-mode or multi-mode fiber optics to extend your network over long distances (several kilometers), connect remote buildings, or create high-performance backbone links to other switches or servers.
✅ The product is used, how can I be sure it works properly?
Each used Cisco SG350-28P-K9 switch is rigorously tested by our specialized network equipment technicians. We check the integrity of all Gigabit Ethernet ports, the operation of PoE+ on each port, Layer 3 routing capability, web and CLI management features, as well as the firmware. Additionally, you benefit from a 30-day warranty to ensure that the hardware meets your professional expectations.
🔧 Do I need technical knowledge to install this manageable switch?
Yes, the Cisco SG350-28P is a manageable professional switch that requires networking administration knowledge to be configured correctly. You will need to master VLAN concepts, IP routing, QoS, network security, and management protocols like SNMP or SSH. The intuitive web interface makes basic configuration easy, but to leverage all advanced Layer 3 features (inter-VLAN routing, complex ACLs, LACP link aggregation), network expertise is recommended. We do not provide technical support for software configuration.
🚚 What is the delivery time and how is the package protected?
Your Cisco switch will be shipped quickly and securely with a professional carrier. You will receive a tracking number to follow your package in real-time. The switch is carefully packaged with shock protection to ensure delivery in perfect condition. A professional invoice with 0% VAT will be included in paper format in the package for your business accounting needs.
🔄 Can I stack multiple SG350 switches together?
Yes, the Cisco 350 series supports stacking, which allows you to manage up to 4 switches as a single logical unit via dedicated SFP ports with appropriate stack cables. This significantly simplifies management, offers increased redundancy, and allows you to gradually expand your network infrastructure while maintaining centralized administration with a single management IP address for the entire stack.
