Fan is operating normally.

Fan fault detected in a chassis cooling fan or a power-supply module fan, or a fan is removed.

Port LEDs and Modes

Each Ethernet port and 10-Gigabit Ethernet module slot has a port LED. These port LEDs, as a group or individually, display information about the switch and about the individual ports. The port mode determines the type of information displayed through the port LEDs. Table 1-8lists the mode LEDs and their associated port modes and meanings.

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 1-9explains how to interpret the port LED colors in different port modes.

On a Catalyst 3750-E switch stack, when you press the Mode button on any switch in the stack, all the switches in the stack change to display the same selected mode. For example, if you press the mode button on the stack master to display SPEED, all the other switches in the stack also display SPEED.

Table 1-8	Port Mode LEDs

Mode LED	Port Mode	Description

STAT	Port status	The port status. This is the default mode.

DUPLX	Port duplex mode	The port duplex mode: full duplex or half duplex.
		Note The 10/100/1000 ports operate only in full-duplex
		mode.

SPEED	Port speed	The port operating speed: 10, 100, or 1000 Mb/s.

STACK1	Stack member status	The stack member status.
	StackWise port status	The StackWise port status. See the “Stack LED” section on
		page 1-12for more information.

PoE2	PoE port power	The PoE port status.
