3.4 Ufikiaji wa Usanidi wa Awali
To perform initial configuration, connect a console cable to the console port on the rear of the switch and use a terminal emulation program on a computer.
4. Maagizo ya Uendeshaji
4.1 Kuwasha na Kuzima
- Washa: Once the power cord is connected, the switch will automatically power on. Observe the system status LEDs for boot-up progress.
- Zima umeme: To power off, disconnect the power cord from the AC outlet. For controlled shutdown, it is recommended to gracefully shut down the operating system via the command-line interface (CLI) before disconnecting power.
4.2 Vifaa vya Kuunganisha
- Bandari za Ethaneti: Connect network devices (computers, servers, IP phones) to the 10/100/1000BASE-T ports using standard Ethernet cables.
- Bandari za Uplink: Use SFP/SFP+ transceivers and fiber optic cables to connect the GbE/10GbE uplink ports to other switches or routers for high-speed backbone connectivity.
4.3 Viashiria vya LED
The front panel of the EX3300-24T features various LED indicators to provide status information:
- SYS LED: Indicates system status (e.g., green for normal operation, amber for minor alarm, red for major alarm).
- ALM LED: Inaonyesha hali ya kengele.
- MST LED: Indicates master status in a Virtual Chassis configuration.
- LED za bandari: Each Ethernet port has LEDs indicating link status and activity.
5. Matengenezo
5.1 Kusafisha
- Keep the switch and its ventilation openings free from dust and debris.
- Tumia kitambaa laini na kikavu kwa ajili ya kusafisha sehemu ya nje. Usitumie visafishaji vya kioevu au erosoli.
