Certify and Increase Opportunity. Switches and LED Switch StatusLEDsYou can use the switch LEDs to monitor switch activity and its performance. Figure 1-23 shows the switch LEDs and the Mode button that you use to select one of the port modes. All LEDs are visible through the GUI management applications—Network Assistant for multiple switches and the device manager for a single switch. The switch software configuration guide describes how to use the CLI to configure and to monitor individual switches and switch clusters. Only the Catalyst 2960 PoE switches have a PoE LED. The four Catalyst 2960 8-port switches and these models do not have an RPS connector or an RPS LED: Catalyst 2960-24-S, Catalyst 2960-24TC-S, Catalyst 2960-48TT-S, Catalyst 2960-48TC-S.

System LEDThe System LED shows whether the system is receiving power and is functioning properly. Table 1-2 lists the LED colors and their meanings.
Table 1-2 System LED
RPS LED The RPS LED shows the RPS status. Table 1-3 lists the LED colors and their meanings. Note The Catalyst 2960 8-port switches, and the Catalyst 2960-24-S, 2960-24TC-S, 2960-48TC-S, and 2960-48TT-S switches do not have an RPS LED.
Table 1-3 RPS LED
For more information about the Cisco RPS 2300 or the Cisco RPS 675, see the related hardware installation guide for that power system. Port LEDs and ModesThe port LEDs, as a group or individually, display information about the switch and about the individual ports (Table 1-4):
Table 1-4 Modes for Port LEDs
Even if the PoE mode is not selected, the PoE LED shows PoE problems when they are detected (Table 1-5). The PoE LED applies only to Catalyst 2960 switches that support PoE.
Table 1-5 PoE Mode LED
To select or change a mode, press the Mode button until the desired mode is highlighted. When you change port modes, the meanings of the port LED colors also change. Table 1-6 explains how to interpret the port LED colors in different port modes.
Table 1-6 Meaning of Port LED Colors in Different Modes on the Switch
Dual-Purpose Port LEDsThe LEDs on a dual-purpose port show whether an RJ-45 connector is connected to the port, or if an SFP module is installed in the slot. See the example in Figure 1-24. You can configure each port as either a 10/100/1000 port through the RJ-45 connector or as an SFP module, but not both at the same time. The LEDs show how the port is being used (Ethernet or SFP module). The LED colors have the same meanings as described in Table 1-4 and Table 1-6. Figure 1-24 Dual-Purpose Port LEDs
Rear Panel Description•Internal Power Supply •Cisco RPS •Console Port Depending on the Catalyst 2960 switch model, the switch can have an RJ-45 console port, a fan exhaust, an RPS connector, and an AC power connector (see Figure 1-25 for an example of a Catalyst 2960 rear panel).
