Control Board LEDs on a QFX3008-I Interconnect Device
Each Control Board has three LEDs on the left side of the module front panel that indicate Control Board status. Each SFP+ management port has two LEDs that indicate link status and activity. See Figure 1.

Table 1 describes these LEDs, their colors and states, and the status they indicate.
