SAS cable connections

The following figure and steps describe how to connect the SAS cables from a single IBM COS Medium or

Large Disk Enclosure connected to a single IBM COS Controller Node, and when to power the unit on.

Figure 25. SAS cable connections

1. Important: The COS Controller Node and the COS Medium or Large Disk Enclosure must be powered

off before attaching the first of the two supplied Mini-SAS HD cables.
Make the first cable connection between the far-left port on the HBA as shown in the figure, and the

top port on the I/O Module installed in the small disk enclosure. The second cable is connected

between the second port from the left on the HBA and the second-to-top port on the I/O Module.

2. Power on the COS medium or large disk enclosure.
3. Wait 3 minutes.
4. Proceed to power on the Controller Node.
