Each server module in an S11 or S31 Node base enclosure has multiple color-coded LEDs that indicate the status of the module and the status of the onboard Ethernet ports. These LEDs are located on the right side of the front of the module. If either of the optional Ethernet cards is installed in the server module, the LEDs for the ports on that card are located on the left side of the module.
The figure below shows the onboard LEDs on a server module and the LEDs on the optional four-port 10GBase-T Ethernet card that can be installed in a server module.
The figure below shows the LEDs on the optional two-port 25Gb Ethernet SFP28 card that can be installed in a server module.
