Chapter 2 Installation Connecting to DC Power The System LED flashes green, and the RPS LED turns off. As each test runs, the port LEDs, starting with number 1, turn off. The port LEDs for ports 2 to 8 each turn off in turn as the system completes a test. When POST completes successfully, the port LEDs return to the status mode display, indicating that the switch is operational. If a test fails, the port LED associated with the test turns amber, and the system LED turns amber. If POST fails, refer to Chapter 3, "Troubleshooting," to determine a course of action. POST failures are usually fatal. Call Cisco Systems immediately if your switch does not pass POST.
