Table 1-5 Meaning of Port Link LED Colors

LED Color	Meaning

Amber	Port disabled, either error or STP1 disabled.
Alternating Green/Amber	Link fault.

1. STP: Spanning Tree Protocol.

The port activity LED blinks green to indicate traffic.

10-Gigabit Ethernet Module Slot Port LEDs

The behavior of the 10-Gigabit Ethernet module slot port LEDs depends on whether an X2 module or a converter module is installed and whether you pressed the Mode button to place the switch module in stack mode.

X2 Module Installed (Only the CBS3120X Switch)

The 10-Gigabit Ethernet module slot LEDs 19 to 22 show the status for ports 19 to 20 and 21 to 22, respectively (see items 8 and 11 in Figure 1-1 on page 1-2). When an X2 module is installed, each pair of LEDs behaves as one. The top pair of LEDs represents the left X2 module in slot 19 to 20, and the bottom pair of LEDs represents the right X2 module in slot 21 to 22.

Table 1-6describes the 10-Gigabit Ethernet slot port LED colors and their meanings.

Table 1-6	Meaning of 10-Gigabit Ethernet Module Slot LED Colors

LED Color		Meaning

Off		No link established.

Solid green		Link established, no activity.

Blinking green		Activity (traffic) on an established link.

Amber		Port disabled, either error or STP disabled.

Alternating green/amber		Link fault.

Converter Module Installed

When a converter module is in one of the 10-Gigabit Ethernet module slots, the LEDs show the status of the SFP modules that are in the converter module. If one converter module is installed in slots 19 and 20, and one converter module is installed in slots 20 and 21, this is how the LEDs correspond to the installed SFP modules:

1.The top LED (19) corresponds to the SFP module in slot 19.

2.The second LED (20) corresponds to the SFP module in slot 20.

3.The third LED (21) corresponds to the SFP module in slot 21.

4.The fourth LED (22) corresponds to the SFP module in slot 22.

See Table 1-6for a description of the 10-Gigabit Ethernet slot port LED colors and their meanings.
