Switch Activity Facts

Switch Activity Facts

In this course, you will learn how to configure the Catalyst 2960 series switch. The 2960 series switch has various status lights (or LEDs) which provide information about the switch's activity.

Light		Meaning
SYST (System)		A single system light gives you information about the overall switch status. Solid green = System is operational Solid amber = System is receiving power but is not functioning properly Off = System is not powered on
RPS (Redundant Power Supply)		A single RPS light shows the status of the redundant power supply. Solid green = RPS is present and ready to provide back-up power Flashing green = RPS is connected, but is unavailable because it is providing power to another device Solid amber = RPS is in standby mode or in a fault condition Off = RPS is off or not properly connected
Port	Each port has a light that indicates the status of the port. By pressing the Mode button, you can view three different types of information for each port.
	Stat (Port status)	When the Mode button selects Stat: Solid green = Link present and is operational Flashing green = Link activity (port is sending or receiving data) Alternating green-amber = Link fault (Error frames can affect connectivity, and errors such as excessive collisions, cyclic redundancy check (CRC) errors, and alignment and jabber errors are monitored for a link-fault indication) Solid amber = Port is blocked by Spanning Tree Protocol (STP) and is not forwarding data Flashing amber = Port is blocked by STP and is sending or receiving packets Off = No link, or port was administratively shut down (if viewing the port status with the GUI, a brown color indicates a shut down port)
	Duplex (Port duplex mode)	When the Mode button selects Duplex: Solid green = Full duplex Off = Half duplex, or no link present (if viewing the port duplex with the GUI, a blue color indicates half duplex)
	Speed (Port speed)	When the Mode button selects Speed: Flashing green = 1000 Mbps (1 Gbps) Solid green = 100 Mbps Off = 10 Mbps, or no link present (if viewing the port speed with the GUI, a blue color indicates 10 Mbps)

On a simple LAN, you can connect the switch to the network, connect devices, and it will automatically begin switching traffic to the correct ports. The switch comes preconfigured to work out-of-the-box without configuration. To customize the switch configuration, connect to the switch in one of the following ways:

• Console connection
• Telnet session
• Web management software (connect through the LAN through a Web browser)

Note: You must configure an IP address for the switch to manage it through a Telnet or Web session.
