Figure 63: SN2100M Port LEDs
In the SN2410M/SN2410bM systems, the status of each pair of adjacent QSFP28 ports is indi-
cated 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.

3.3 Inventory Information
The system’s inventory parameters (such as Serial Number, Part Number, GUID and MAC
address) can be extracted from the inventory pull-out tab on the lower right side of the front
panel. In some systems, there is no pull-out tab, and the information is provided on labels in sev

eral locations.
