3. Operating the Switch
Once the switch is physically installed and powered on, it will begin its boot sequence. The front panel provides indicators for system status and port activity.
3.1 Front Panel Indicators
- System Status LEDs: Monitor the ALM (Alarm), SYS (System), and MST (Master) LEDs for overall device health.
- Port Activity LEDs: Each SFP+ port has an associated LED that indicates link status and activity. A green light typically signifies an active link.
