The front panel LEDs provide visual status of the switch's operation:

• SYST (System): Nunjukkeun status sistem sacara umum (contona, héjo pikeun operasi normal, konéng pikeun gangguan).
• RPS (Redundant Power System): Indicates the status of an optional external redundant power supply.
• STACK: Indicates the status of the switch in a StackWise-480 stack.
• Poe: Indicates the Power over Ethernet status for the ports.
• LED Status Port: Each port has LEDs indicating link status, activity, speed, and duplex mode.
