2.5-inch drive backplane cable routing
Follow instructions in this section to route the cables for the 2.5-inch drive backplane.
Note
- Connections between connectors; 1↔1, 2↔2, 3↔3, ... n↔n
- When routing the cables, make sure that all cables are routed appropriately through the corresponding cable guides and cable clips.
