3. Postavljanje i instalacija
3.1. Priprema lokacije
- Osigurajte odgovarajuću ventilaciju oko prekidača.
- Place the switch on a stable, flat surface or mount it using the provided kit.
- Keep the switch away from direct sunlight, heat sources, and excessive moisture.
- Ensure a reliable power source is available.
3.2. Spajanje prekidača
- Povežite mrežne uređaje: Connect your computers, servers, IP phones, or other network devices to the RJ-45 Gigabit Ethernet ports (1-8) using standard Ethernet cables. For devices requiring power over Ethernet, ensure they are PoE-compatible.
- Poveži uzlaznu vezu (opciono): If connecting to another switch or router, use one of the Gigabit Ethernet ports (1-10) or the SFP ports (G9, G10) with appropriate transceivers and fiber optic cables.
- Priključite napajanje: Connect the power adapter to the 12V DC power input on the rear panel of the switch, then plug the power cord into an electrical outlet. The System LED on the front panel should illuminate.
- Pristup početnoj konfiguraciji: For initial setup, connect a computer directly to any of the switch's RJ-45 ports. The switch typically obtains an IP address via DHCP by default. Refer to the Quick Start Guide or the full user documentation for details on accessing the web-bazirano upravljanje interfejsom.
