How to use

Install the switch in a rack or on a stable surface and connect power. Use the Gigabit RJ-45 ports to connect endpoints such as workstations, IP phones and access points; connect uplink ports to the aggregation layer or core using 10G SFP+ modules where required. Configure basic Layer 2 settings and PoE allocation through the device dashboard or management interface according to your network plan, and verify VLANs, port settings and security policies before putting devices into production.

Recommendations

Place the switch in a temperature-controlled environment with adequate ventilation, use recommended SFP+ modules for 10G links, monitor PoE budget to avoid over-allocation, and keep firmware updated to maintain security and interoperability.
