Chapter 1 Product Overview Front-Panel Description Port LEDs and Modes Each RJ-45 port and GBIC module slot has a port LED. These port LEDs, as a group or individually, display information about the switch and about the individual ports. The port modes determine the type of information displayed through the port LEDs. Table 1-7 lists the mode LEDs and their associated port mode and meaning.

Solid green Link present. Flashing green Activity. Port is transmitting or receiving data. Alternating green-amber Link fault.
Chapter 1 Product Overview Front-Panel Description Bandwidth Utilization The UTIL mode on the switch shows the current bandwidth in use by the switch. If all possible port LEDs are green, bandwidth utilization is in the 50 to 100% range. Every port LED that is off (black) divides this range by two. For specific switches, see Figure 1-12 through Figure 1-16. Figure 1-12 shows the bandwidth utilization percentages displayed by the LEDs on the Catalyst 3550-12T switch.

You can also connect the Cisco RPS 300 Redundant Power System to provide backup power if the switch internal power supply should fail. Note The Catalyst 3550 switch and the Cisco RPS 300 should be connected to the same AC power source.
Chapter 1 Product Overview Management Options Note Warning The Cisco RPS 300 does not support the Catalyst 3550-24-DC switch. Attach only the Cisco RPS 300 (model PWR300-AC-RPS-N1) to the RPS receptacle. The RPS is a redundant power system that can support six external network devices and provides power to one failed device at a time. It automatically senses when the internal power supply of a connected device fails and provides power to the failed device, preventing loss of network traffic.

Chapter 2 Installing and Starting the Switch Running Post Step 8 Remove the tape from the circuit-breaker switch handle, and move the circuit-breaker handle to the on position. Caution To comply with the intrabuilding lightning surge requirements, intrabuilding wiring must be shielded, and the shield for the wiring must be grounded at both ends. Caution The Catalyst 3550-24-DC switch is suitable only for intrabuilding or nonexposed wiring connections.
Chapter 2 Installing and Starting the Switch Connecting to the 10/100 and 10/100/1000 Ports To maximize performance, choose one of these methods for configuring the Ethernet ports: • Let the ports autonegotiate both speed and duplex. • Set the port speed and duplex parameters on both ends of the connection. Follow these steps to connect to 10BASE-T, 100BASE-TX or 1000BASE-T devices: Caution To prevent electrostatic-discharge (ESD) damage, follow your normal board and component handling procedures.

C H A P T E R 3 Troubleshooting The LEDs on the front panel provide troubleshooting information about the switch. They show failures in the power-on self-test (POST), port-connectivity problems, and overall switch performance. For a full description of the switch LEDs, see the “LEDs” section on page 1-10. You can also get statistics from the browser interface, from the command-line interface (CLI), or from a Simple Network Management Protocol (SNMP) workstation.
Chapter 3 Troubleshooting Diagnosing Problems When POST completes successfully, the port LEDs return to the status mode display, showing that the switch is operational. If a test fails, the port LED associated with the test turns amber, and the system LED turns amber. Note POST failures are usually fatal. Call Cisco Systems if your switch does not pass POST.

Appendix C Translated Safety Warnings Laser Beam Exposure Warning Aviso: Los puertos de apertura del módulo de procesador de supervisión de modo único 100BASE-FX pueden emitir radiación láser invisible. Evite exponerse a la misma y no mire directamente a las aperturas. Varning! Osynlig laserstrålning kan eventuellt avges från öppningsportarna på 1000BASE-FX enkelt läge övervakarmotormodul. Undvik att utsätta dig för strålning och stirra inte in i öppna hål.
