QFX5110 Network Port LEDs

The Link/Activity LED configuration for QFX5110-48S uses bi-colored LEDs. The link LED indicates link activity or a fault. See Table 1.

QFX5110-48S	SFP+	Link and ActivityStatus See Table 3,

As shown in Table 1 and Table 4 there are four bi-color LEDs for each QSFP+ access port. The first LED indicates link presence and activity, while the remaining LEDs indicate status. Table 2 describes how to interpret the Link/Activity QSFP28 port LEDs, counting from the left-most position.

Table 2: Network Port LEDs on QSFP28 Ports on a QFX5110
Position	Color	State	Description
1–4	Unlit	Off	The port is administratively disabled, there is no power, the link is down, or there is a fault.
1	Green	On steadily	A link is established (either 100-Gigabit or 40-Gigabit, non-channelized) but there is no link activity. When this LED is on, the LEDs in positions 2 to 4 are off.
1	Green	Blinking	A link is established (either 100-Gigabit or 40-Gigabit, non-channelized) and there is link activity.
2-4	Green	On steadily	A 40-Gigabit link is established in channelized mode, but there is no link activity.
2-4	Green	Blinking	A 40-Gigabit link is established in channelized mode, and there is link activity.

Table 3 describes how to interpret the Link/Activity LEDs on SFP+ ports.

LED	Color	State	Description
Link/Activity	Unlit	Off	The port is administratively disabled, there is no power, the link is down, or there is a fault.
	Green	On steadily	A link is established, but there is no link activity.
	Green	Blinking	A link is established, and there is link activity.
Status	Unlit	Off	The link is down or there is a fault.
	Green	On steadily	A 10-Gigabit Ethernet transceiver is installed in the port and link is established.
	Green	Blinking	A 1-Gigabit Ethernet transceiver is installed in the port and the link is established.
