MSM LEDs
Table 5 describes the LED activity on the MSM-G8X and MSM-48.
The LEDs on the management Ethernet port are not labeled. The LED on the right is the link LED, and the one on
the left is the activity LED.
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
This section describes the three different series of BlackDiamond 8800 I/O modules available for use in
a BlackDiamond 8800 series switch: the BlackDiamond 8800 original series I/O modules, the
BlackDiamond 8800 a-series I/O modules, and the BlackDiamond 8800 e-series I/O modules.
No configuration information is stored on the I/O modules; all configuration information is stored on
the MSM(s).
When a BlackDiamond 8800 series switch is powered on, the software generates a default configuration
for any slots that contain I/O modules. The default configuration allows the I/O module ports to

LED Color Indicates
SYS/STA Green blinking Normal operation is occurring.
Amber blinking The status LED flashes amber while diagnostic tests are running on
the module. If a diagnostic test fails, the status LED becomes solid
amber. The LED resets if the diagnostics are terminated. The LED
returns to flashing amber if another diagnostic test is started.
Amber Diagnostic failure has occurred.
Off Switch is not receiving power.
MSTR/DIAG Green Module is operating as primary MSM.
Amber Module is operating as backup (secondary) MSM.
Green blinking Power-on self-test (POST) is running.
Off Normal operation for diagnostics.
ERR Amber A critical software error has been logged since power-up.
Off Normal operation is occurring.
ENV Green Environment (temperature, fan, power supply) is operating properly.
Amber Environmental failure has occurred.
