Front-Panel Description

LEDs

You can use the LEDs to monitor switch activity and performance. The locations and numbers of the

LEDs vary among switch models. The location of the Mode button that you use to select the port mode

also varies by model. See these figures:

• Figure 1-15 for the Catalyst 2950-12, 2950-24, 2950C-24, 2950SX-24, and 2950T-24 switches

• Figure 1-16 for the Catalyst 2950G-12-EI, 2950G-24-EI, and 2950G-24-EI-DC switches

• Figure 1-17 for the Catalyst 2950G-48-EI, Catalyst 2950SX-48-SI, and Catalyst 2950T-48-SI

switches

• Figure 1-18 for the Catalyst 2950ST-8 LRE and 2950ST-24 LRE switches

• Figure 1-19 for the Catalyst 2950ST-24 LRE 997 switches

All LEDs (except the utilization meter [UTIL]) are visible through the GUI management

applications—the Network Assistant application for multiple switches and the device manager for a

single switch. The switch software configuration guide describes how to use the command-line interface

(CLI) to configure and to monitor individual switches and switch clusters.
