Access Port and Uplink Port LEDs on a QFX3600 or QFX3600-I Device
Each access port and uplink port in a QFX3600 device has two LEDs (see Figure 1).

The LEDs labeled Link/Activity LED in Figure 1 indicate link activity or faults. The LEDs labeled Status LED in Figure 1 indicate link status.
Table 1 describes the QSFP+ access port LEDs.

A link is established, but there is no link activity. Note:
The LED is lit green when at least one of the four 10-Gigabit Ethernet SFP+ breakout links is established. |
