Installing the controller hardware 11
CAUTION: Do not operate the server for long periods with the
access panel open or removed. Operating the server in this manner
results in improper airflow and improper cooling that can lead to thermal
damage.
9. If the controller was hot-plugged, power up the slot.
Connecting external storage
1. Power down the server.
2. Connect an external SAS cable to the external port of the controller.
NOTE: You do not have to disconnect any internal drives on
shared internal port 1I because the controller preferentially discovers
devices attached to port 1E. However, drives on the shared internal port
are unavailable until you disconnect the external storage device.
3. Tighten the lock screws on the cable connector.
4. Attach the other end of the cable to the SAS input connector of the external
storage enclosure.
IMPORTANT: Drives that are to be used in the same array must
be of the same type, either all SAS or all SATA. (Parallel SCSI drives
cannot be used with this controller.)
5. Tighten the lock screws on the cable connector.
6. Power up the enclosure.
7. Power up the server.
