Chapter 1 Product Overview

Other Features

Stack Master LED

The Stack Master LED (MSTR) shows the stack master status. Table 1-3lists the LED colors and their meanings.

Table 1-3	Stack Master LED

Color	Description

Off	Switch is not the stack master.

Green	Switch is the stack master or a standalone switch.

Amber	An error occurred during stack master election or another type of stack error occurred.

Stack Member LED

The Stack Member LED (MMBR) shows the switch stack membership number, which ranges

from 1 to 9. The Stack Member LED blinks a number of times equal to the membership number of the switch, pauses, and then repeats the process until you turn off stack mode or until stack mode times out.

Table 1-4lists the LED colors and their meanings when stack mode is on. When stack mode is off, the Member LED is off.

Table 1-4 Member LED With Stack Mode On

Color	Description

Off	Pause between blinking stack membership number. Duration is 5 seconds. After
	pause, LED changes to blinking green.

Blinking green	A total of n on-off cycles with n = switch stack membership number in range 1 to 9.
	After n on-off cycles, blinking stops, and LED turns off.

UID and Health LEDs

The UID and Health LEDs are controlled by the blade enclosure software (Onboard Administrator). The UID LED is on when the switch module is identified by the blade enclosure. The Health LED is green during normal operation; it is amber when a failure is detected.

RJ-45 Uplink Port LEDs

The external 10/100/1000BASE-T copper Gigabit Ethernet uplink port LEDs display link and activity information about each individual port. These LEDs are on the top left and right, respectively, of each RJ-45 port (see item 9 in Figure 1-1 on page 1-2). Table 1-5describes the port link LED colors and their meanings.

Table 1-5 Meaning of Port Link LED Colors

				LED Color	Meaning

				Off	No link established.

				Solid green	Link established, no activity.

				Blinking green	Traffic on an established link.
