Why Buy Switches from Gigadata IT?
Choosing the right switch impacts uptime, security, and user experience. Our portfolio covers essential needs: high-density Fast/Gigabit access, 10GbE uplinks via SFP/SFP+, advanced Layer-3 features, and robust PoE budgets for wireless and CCTV. Refurbished units provide enterprise reliability at a lower total cost, while open-box or new devices suit projects that require maximum lifecycle or vendor support. Every unit is inspected, reset to factory defaults, and shipped ready to configure.

- ✔ Options for PoE/PoE+ to power APs, VoIP, and cameras
- ✔ Managed features: VLANs, QoS, ACLs, Spanning Tree, static routing on L3 models
- ✔ Tested hardware with 30-day warranty and fast fulfillment
- ✔ Competitive pricing and offers for bulk orders
How to Pick the Right Network Switch
Port density: Count current endpoints and add 20–30% headroom (8/24/48 ports). For small branches, 8–16 ports are often enough; for floors and classrooms, 24/48 ports are standard.
Performance: Prefer Gigabit access for desktops and APs; use 10GbE uplinks on aggregation or when many clients share a single uplink. Verify backplane capacity so the switch can forward at line rate.
PoE budget: Sum power draw of devices (APs, IP phones, cameras). Choose PoE+ if you have multi-radio Wi-Fi 6/7 APs or PTZ cameras. Consider future growth to avoid external injectors.
Layer & features: L2 switches handle VLANs and STP; L3 adds inter-VLAN routing, static routes, and sometimes OSPF/RIP. For voice/video, enable QoS and storm control. For security, apply port security and ACLs.
Environment: For factories or cabinets without climate control, choose industrial models (hardened chassis, extended temperature, DC power options).

Testing, Reset & Warranty
Every refurbished switch is function-tested: power supplies are load-tested, all copper ports are checked for link and throughput, PoE is verified with real loads, and SFP slots are validated with optics. Devices are wiped and returned to factory defaults with stable firmware. Gigadata IT includes a 30-day warranty by default; extended options are available on request so you can deploy with confidence.
Common Use Cases and Architectures
Office access: 24/48-port managed switches with PoE+ power Wi-Fi and VoIP. Use VLANs to separate users, voice, and cameras, and trunk uplinks to your core or firewall. Campus & education: Stackable models simplify management across buildings; enable LLDP-MED and 802.1X for secure onboarding. Retail & hospitality: Quiet, fanless options are ideal for front-of-house areas; PoE powers APs, kiosks, and IP POS. Industrial/IoT: Rugged switches provide DIN-rail mounting, redundant power, and extended temperature ranges for factory floors and cabinets. Data center & server rooms: Choose high-throughput models with SFP/SFP+ uplinks and ample buffer memory; use L3 for inter-VLAN routing near servers.
Best Practices for a Stable, Secure Network
- Enable VLANs and trunk uplinks; avoid flat L2 domains to reduce broadcast storms.
- Use STP/RSTP where necessary and disable unused ports.
- Apply QoS for voice/video; mark and prioritize traffic at the edge.
- Harden access: port-security, DHCP snooping, dynamic ARP inspection.
- Keep a standard template for SNMP, NTP, syslog, AAA, and backups.
FAQs
Do I need PoE or PoE+? If you power Wi-Fi 6/7 APs or PTZ cameras, choose PoE+. For phones and basic APs, standard PoE is usually enough.
Do you supply optics and accessories? We can bundle SFP/SFP+ modules, DAC cables, rails, and rack shelves in the same quote.
