Figure 79: Sn201Port Leds; Figure 80: Sn2100 Port Leds - Mellanox Technologies Spectrum SN2740 Hardware User Manual

In the SN2410 systems, the status of each pair of adjacent QSFP28 ports is indicated by four
LEDs, as shown in the picture above:
• While the bottom LEDs signify the port status in regular condition, the upper LEDs
operate only when the port is split.
• When one port is split to two, a connection of 100GbE can be utilized in its adjacent
port.
• When one port is split to four, it adjacent port is canceled.
• If the ports run at a 100GbE/40GbE speed each, the two lower LEDs (2 and 4) will light
green.
• If the ports run at a 50GbE speed each, the left LEDs (1 and 2) will light green for the
upper port, and the right LEDs (3 and 4) will light green for the lower port.
• If the ports run at a 25GbE/10GbE speed each, all LEDs may light green, according to
the selected lane.
