See the ExtremeXOS 12.1 Concepts Guide and the ExtremeXOS 12.1 Command Reference Guide for more
information about numbering conventions for the modules and ports, as well as configuration and display
information.
MSM LEDs
Table 3 describes the LED activity on the BlackDiamond 8800 series MSMs.
NOTE
The LEDs on the management Ethernet port are not labeled. On most modules, the LED on the right is the link
LED, and the one on the left is the activity LED. On the MSM-48c, the left LED indicates link status, and the right
LED indicates link activity by blinking green.
NOTE
The data port LEDs on the MSM-G8X operate the same as the port status LEDs on the G24X I/O module.
