5. Cyfarwyddiadau Gweithredu
5.1. Pweru Ymlaen ac i ffwrdd
- Pŵer Ymlaen: Connect the power cord to a power source. The switch will automatically power on.
- Pwer i ffwrdd: Disconnect the power cord from the electrical outlet. For controlled shutdown, use the appropriate CLI commands before disconnecting power.
5.2. Dangosyddion LED
Mae LEDs y panel blaen yn darparu gwybodaeth am statws:
- LED System: Yn dynodi statws cyffredinol y system (e.e., gwyrdd ar gyfer gweithrediad arferol, ambr am fai).
- LEDs Statws Porthladd: Indicate link status and activity for each network port (e.g., green for link, blinking green for activity).
- PoE LED: Indicates Power over Ethernet status.
5.3. Cysylltu Dyfeisiau Rhwydwaith
Connect Ethernet devices (computers, servers, access points) to the 48 Gigabit Ethernet ports using standard RJ-45 cables. For high-speed uplinks, use appropriate transceivers and fiber optic cables in the 10 Gigabit Ethernet uplink ports.
5.4. Management Access
The switch can be managed via:
- Porth Consol: For initial setup and direct CLI access.
- Web-based Interface (GUI): Mynediad trwy a web browser after initial IP configuration.
- Secure Shell (SSH): For secure remote CLI access.
