Access Port and Uplink Port LEDs on a QFX5100 Device

The Link/Activity and Status LED configuration for QFX5100 switches use bi-colored LEDs. The link LED indicates link activity or a fault. The status LED indicates transceiver presence. See Table 1 to locate the position and type of LED for your QFX5100 model.

Table 2 describes how to interpret the SFP+ port LEDs.

As shown in Table 1, there are four bi-color LEDs for each QSFP+ port. The first LED is used and the remaining LEDs are not used when the interface is configured for 40-Gigabit Ethernet and connected to a QSFP+ transceiver. All four LEDs are used when the interface is configured for 10-Gigabit Ethernet and the port is connected using an optical split cable or a copper DACBO cable. Table 3 describes how to interpret the QSFP+ LEDs.
