Color State QFX5200-32C and QFX5200-32C-L Descripon
Unlit O The port is administravely disabled, there is no power, the link is down, or there is a
fault.
When congured for 25-Gigabit Ethernet, the LED remains unlit only if all four of the
25-Gigabit Ethernet QSFP+ breakout links are down.
Green On
steadily
A link is established, but there is no link acvity.
When congured for 25-Gigabit Ethernet, the LED is lit green when at least one of the
four 25-Gigabit Ethernet QSFP+ breakout links is established.
Blinking A link is established, and there is link acvity.
When congured for 25-Gigabit Ethernet, the LED is lit green when at least one of the
four 25-Gigabit Ethernet QSFP+ breakout links is established.
Amber Blinking The beacon is enabled on the port.
As shown in Table 5 on page 12, there are four bi-color LEDs for each QSFP+ port. The rst LED is
used and the remaining LEDs are not used when the interface is congured for 100-Gigabit Ethernet
and connected to a QSFP28 transceiver. All four LEDs are used when the interface is congured for 25-
Gigabit Ethernet and the port is connected using an opcal splier cable or a copper DACBO cable.
Table 5 on page 12 describes how to interpret the QSFP+ LEDs.

Color State Descripon
Unlit O The port is administravely disabled, there is no power, the link is down,
or there is a fault.
NOTE: When congured for 10-Gigabit Ethernet, the LED remains unlit
only if all four of the 10-Gigabit Ethernet SFP+ breakout links are down.
