Networking Ports LEDs Specifications

There are two I/O LEDs per port to indicate port speed and link status.
• LED0 is a bi-color LED (Yellow and Green)
Single-Host Mode: x1 PCIe x16
Socket Direct Mode: x2 PCIe x8
Socket Direct Mode: x4 PCIe x4
Multi-Host Mode: x2 PCIe x8
Multi-Host Mode: x4 PCIe x4
The network ports are compliant with the IEEE 802.3 Ethernet
standards listed in Features and
transmitted through the networking connectors on the adapter card.
The network ports are compliant with the InfiniBand Architecture
Specification, Release 1.5. InfiniBand traffic is transmitted through
the cards' networking connectors.
