Understanding POST Results

Understanding POST Results

Each time the switch is powered on, eight POSTs run automatically to check the most important system components before the switch begins forwarding packets. When the switch begins its POST, the port status LEDs turn amber for 2 seconds, and then they turn green. As each test runs, the port status LEDs turn off, starting with number 1x. The port status LEDs for ports 2x to 8x each turn off in turn as the system completes a test.

When the POST completes successfully, the port status LEDs go off, indicating that the switch is operational. If a test fails, the port status LED associated with the test turns amber, and the system LED turns amber. Table 3-1 lists the eight POST tests and their associated LEDs.

Note POST failures are usually fatal. Call Cisco Systems if your switch does not pass POST.
