Cisco Systems 2960 specifications Port Mode LED Color Meaning

Chapter 1 Product Overview

Front Panel Description

			Table 1-5	Meaning of LED Colors in Different Modes on the Switch
			Port Mode	LED Color	Meaning
			STAT	Off	No link, or port was administratively shut down.
			(port status)
				Green	Link present.
				Blinking green	Activity. Port is sending or receiving data.
				Alternating	Link fault. Error frames can affect connectivity, and errors such as
				green-amber	excessive collisions, cyclic redundancy check (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 switch for possible loops.
				Blinking amber	Port is blocked by STP and is sending or receiving packets.
			DUPLX	Off	Port is operating in half duplex.
			(duplex)
				Green	Port is operating in full duplex.
			SPEED	10/100/1000 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.
				SFP module 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 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 in the Catalyst 2960 switches.
			PoE	PoE port power	The PoE status.
			Even if PoE mode is not selected, the PoE LED still shows PoE problems when they are detected.
			Table 1-6lists the PoE mode LED colors and their meanings. The PoE LED applies only to Catalyst 2960
			switches that support PoE.
Table 1-6	PoE Mode LED
Color		PoE Status
Off		PoE mode is not selected. None of the 10/100 or 10/100/1000 PoE ports have been denied power or are
		in a fault condition.
Green		PoE mode is selected, and the PoE status is shown on the port LEDs.
Blinking amber		PoE mode is not selected. At least one of the 10/100 PoE ports has been denied power, or at least one of
		the ports has a PoE fault.
