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.

511, there are four bi-color LEDs for each QSFP+ port. The first LED is used
shows the location of the LED next to the fan module.
Description
The port is administratively disabled, there is no power, the
link is down, or there is a fault.
NOTE: When configured for 10-Gigabit Ethernet, the LED
remains unlit only if all four of the 10-Gigabit Ethernet SFP+
breakout links are down.
A link is established, but there is no link activity.
NOTE: When configured for 10-Gigabit Ethernet, the LED is
lit green when at least one of the four 10-Gigabit Ethernet
SFP+ breakout links is established.
A link is established, and there is link activity.
NOTE: When configured for 10-Gigabit Ethernet, the LED is
