Front Panel Description

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 1-7explains how to interpret the port LED colors in different port modes.

Table 1-7		Meaning of Port LED Colors in Different Modes on the Switch

	Port Mode		LED Color	Meaning

	PoE		Off	PoE is off.
				If the powered device is receiving power from an AC power source, the PoE port LED
				is off even if the powered device is connected to the switch port.

			Green	PoE is on. The port LED is green only when the switch port is providing power.

			Alternating green	PoE is denied because providing power to the powered device will exceed the 370 W
			and amber	switch power capacity.

			Blinking amber	PoE is off due to a fault.

				Caution PoE faults are caused when noncompliant cabling or powered devices are
						connected to a PoE port. Use only standard-compliant cabling to connect
						Cisco pre-standard IP Phones or wireless access points or
						IEEE 802.3af-compliant devices to PoE ports. You must remove from the
						network the cable or device that causes a PoE fault.


			Amber	PoE for the port has been disabled. PoE is enabled by default.

	STAT		Off	No link, or port was administratively shut down.
	(port status)
	(port status)		Green	Link present.
			Green	Link present.

			Blinking green	Activity. Port is sending or receiving data.

			Alternating	Link fault. Error frames can affect connectivity, and errors such as excessive
			green-amber	collisions, CRC errors, and alignment and jabber errors are monitored for a link-fault
				indication.

			Amber	Port is blocked by Spanning Tree Protocol (STP) and is not forwarding data. After a
				port is reconfigured, the port LED can remain amber for up to 30 seconds as STP
				checks the network topology for possible loops.

			Blinking amber	Port is blocked by STP and is not sending or receiving packets.

	DUPLX		Off	Port is operating in half duplex.
	(duplex)
	(duplex)		Green	Port is operating in full duplex.
			Green	Port is operating in full duplex.

	SPEED		10/100 and 10/100/1000 ports

			Off	Port is operating at 10 Mb/s.

			Green	Port is operating at 100 Mb/s.

			Flashing green	Port is operating at 1000 Mb/s.

			SFP ports

			Off	Port is operating at 10 Mb/s.

			Green	Port is operating at 100 Mb/s.

			Blinking green	Port is operating at 1000 Mb/s.
				Note The 1000BASE-T SFP modules can operate at 10, 100, or 1000 Mb/s in
					full-duplex mode or at 10 or 100 Mb/s in half-duplex mode.

2960 specifications

Cisco Systems 2960 series switches are a prominent solution in the networking landscape, known for their reliability, scalability, and feature-rich offerings. Ideal for small to medium-sized enterprises, these switches provide a robust foundation for network infrastructure, ensuring optimal performance and connectivity.

One of the standout features of the Cisco 2960 series is its Layer 2 switching capabilities. The switches support multiple VLANs (Virtual Local Area Networks), allowing network administrators to segment traffic efficiently and enhance security protocols. This is crucial in modern networks where managing traffic and isolating sensitive information is a priority.

The Cisco 2960 series also incorporates advanced Quality of Service (QoS) features, enabling the prioritization of critical applications and services. This functionality ensures that time-sensitive data, such as voice and video traffic, maintains a high quality of service even in congested networks. With support for IEEE 802.1p and DSCP marking, administrators can fine-tune their network performance to meet specific organizational needs.

Power over Ethernet (PoE) is another significant characteristic of the Cisco 2960 series. This feature allows switches to deliver electrical power alongside data over Ethernet cables to devices such as IP phones, wireless access points, and surveillance cameras. With PoE, organizations can reduce clutter from power cables and increase deployment flexibility for various devices.

In terms of security, the Cisco 2960 series is equipped with a range of integrated security features. The switch supports port security, 802.1X authentication, and Access Control Lists (ACLs), providing robust defenses against unauthorized access and potential network vulnerabilities. These security measures are essential for protecting sensitive data and ensuring compliance with industry regulations.

Moreover, the Cisco 2960 series offers enhanced network management capabilities with Cisco's Intelligent Network Services. This includes support for Simple Network Management Protocol (SNMP), Cisco Prime, and Embedded Event Manager (EEM), allowing for efficient monitoring, troubleshooting, and policy enforcement across the network.

Additionally, the Cisco 2960 switches provide various models and configurations, catering to different networking needs. Options include models with varying port densities, uplink configurations, and stacking capabilities, making it easy for organizations to choose solutions that align perfectly with their requirements.

In summary, the Cisco 2960 series is a versatile and essential component of modern networking environments. Its advanced features, including Layer 2 support, QoS, PoE, robust security, and diverse management tools, make it an excellent choice for organizations looking to build a strong and secure network infrastructure.
