Lenovo ThinkSystem SR550 Setup Manual page 33

Note: Disengage all latches, release tabs, or locks on cable connectors when you disconnect cables from
the system board. Failing to release them before removing the cables will damage the cable sockets on the
system board, which are fragile. Any damage to the cable sockets might require replacing the system board.
Some options, such as RAID adapters, might require additional internal cabling. See the documentation that
is provided for the option to determine any additional cabling requirements and instructions.
