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.
Connecting to a 10/100 Port
The switch 10/100 ports configure themselves to operate at the speed of attached
devices. If the attached ports do not support autonegotiation, you can explicitly
set the speed and duplex parameters.
Connecting devices that do not autonegotiate or that have their speed and duplex
parameters manually set can reduce performance or result in no linkage. To
maximize performance, choose one of these methods for configuring the 10/100
Ethernet ports:
• Let the ports autonegotiate both speed and duplex.
• Set the port speed and duplex parameters on both ends of the connection.
