RPS LED

The RPS LED shows the RPS status. Table 1-3lists the LED colors and their meanings.

Table 1-3 RPS LED

Color	RPS Status
Off	RPS is off or not properly connected.
Solid green	RPS is connected and ready to provide back-up power, if required.
Blinking green	RPS is connected but is unavailable because it is providing power to another device
	(redundancy has been allocated to a neighboring device).
Solid amber	The RPS is in standby mode or in a fault condition. Press the Standby/Active button
	on the RPS, and the LED should turn green. If it does not, the RPS fan could have
	failed. Contact Cisco Systems.
Blinking amber	The internal power supply in a switch has failed, and the RPS is providing power
	to the switch (redundancy has been allocated to this device).

For more information about the Cisco RPS 300 or the Cisco RPS 675, see the documentation included with the RPS.

Port LEDs and Modes

Each RJ-45 port and GBIC 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 1-4lists the mode LEDs and their associated port modes and meanings.

To select or change a mode, press the Mode button (or Mode label on the Catalyst 3550-48 switch) until the desired mode is highlighted. When you change port modes, the meanings of the port LED colors also change. Table 1-5explains how to interpret the port LED colors in different port modes.

You can also use the Mode button to activate the Express Setup program or to clear the switch IP address and all switch settings. See the “Clearing the Switch IP Address and Configuration” section on page 3-1for more information.

Table 1-4 Port Mode LEDs

	Mode LED	Port Mode	Description
	STATUS	Port status	The port status. This is the default mode.
	UTIL1	Switch utilization	The current bandwidth in use by the switch. (See Figure 1-4
			through Figure 1-8.)
	DUPLX	Port duplex mode	The port duplex mode: full duplex or half duplex.
