System Port LEDs
SN2100
SN2201
RJ45:
QSFP28:
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.
