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.
I/O Modules
The following series of I/O modules are available for the BlackDiamond 8800 series switches:
● BlackDiamond 8800 original series I/O modules (see page 25 )
● BlackDiamond 8800 a-series I/O modules (see page 28 )
● BlackDiamond 8800 c-series I/O modules (see page 32 )
● BlackDiamond 8800 e-series I/O modules (see page 36 )
