There are four LEDs for each port (labeled 2, 3, 4, and 5 in Figure 212 on page 569). If a port is configured
to operate at 10-Gbps speed by using breakout cables, four 10-Gbps interfaces are created and the four
LEDs for that port becomes operational. Each of these LEDs indicates the link activity on the corresponding
interface. If a port is configured to operate at 40-Gbps or 100-Gbps speed, the LED labeled 2 for that port
in Figure 212 on page 569 becomes operational and indicates the link activity on the corresponding port.

The Table 121 on page 570 describes the link activity LED on 10/100/1000BASE-T network ports, SFP
network ports, SFP+ uplink ports, SFP+ uplink module ports, built-in QSFP+ ports, QSFP+ uplink module
ports, and QSFP+/QSFP28 uplink module ports.
