10/100/1000 Ports
The 10/100/1000 ports use RJ-45 connectors and Category 5 UTP cabling. These
ports can be explicitly set to operate at 10 or 100 Mbps in half- or full-duplex
mode or at 1000 Mbps in full-duplex mode. The default duplex setting is full
duplex. They can also be set for speed and duplex autonegotiation, compliant with
IEEE 802.3ab. In all cases, the cable length from a switch to an attached device
cannot exceed 328 feet (100 meters).
LEDs
You can use the LEDs to monitor switch activity and performance. Figure 1-6
shows the location of the LEDs and the Mode button that you use to select the port
mode. Changing the port mode changes the information provided by each port
status LED.
All of the LEDs described in this section except the utilization meter (UTIL) are
visible in the Cluster Management Suite (CMS). The Catalyst 2950 Desktop
Switch Software Configuration Guide describes how to use CMS to manage
individual switches and switch clusters.
