LAN Ports
The motherboard has 13 LAN ports. LAN1 – LAN9 are 1G ports and LAN10 - LAN13 are
10G SFP+ ports. In addition to the LAN ports, the motherboard offers a dedicated IPMI LAN
port. Refer to the table below for the pin definitions.
Warning: The IPMI Ethernet and LAN 1-9 (intra-building ports) of the equipment or
subassembly are suitable for connection to intra-building or unexposed wiring or cabling
only. The intra-building ports of the equipment or subassembly MUST NOT be metallically
connected to interfaces that connect to the OSP or its wiring. These interfaces are designed
for use as intra-building interfaces only (Type 4 or 4a ports as described in GR-1089-CORE)
and require isolation from the exposed OSP cabling. The addition of Primary Protectors is
not sufficient protection in order to connect these interfaces metallically to OSP wiring.
COM Port/Header
The motherboard has one COM port on the I/O front panel and one COM header on the
motherboard to provide serial connections.
