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.

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.

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.

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.

Blinking

A 40-Gigabit link is established in channelized mode, and there is link activity.

All

Amber

Blinking

All four LEDs blink to indicate the beacon function was enabled on the port.
