E3.S 2/3, 4/5, 6/7, and 8/9 drives in MCIO configuration cable routing

Use this information to route the cables for E3.S 2/3, 4/5, 6/7, and 8/9 drives in MCIO configuration.

When installing four E3.S drives in MCIO configuration, follow the grouping rule below:

This section provides information on cable routing of the two drive groups:
