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