Server without Compute Complex Neptune Core Module

This section provides cable routing information for the ConnectX-8 InfiniBand adapter when Compute Complex Neptune Core Module is not installed.

Table 1: The server is equipped with one processor and one ConnectX-8 adapter.
Table 2: The server is equipped with two processors and one ConnectX-8 adapter.
Table 3: The server is equipped with two processors and two ConnectX-8 adapters.

Note

LP: Low-profile
FH: Full-height
