As shown in Figure 42 on page 192, 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 39 on page 193 describes how to
interpret the QSFP+ LEDs.

DescriptionStateColor
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.
OffUnlit
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.
On steadilyGreen
A link is established, and there is 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.
Blinking
All four LEDs blink to indicate the beacon function was enabled on
the port.
