QuestionQ11

Deployment

A customer is installing an ES40 expansion shelf onto a Dell PowerProtect DD9410 system to expand its storage capacity. When routing and connecting the SAS cables to the controller, what action should the technician take?

  • A Ensure there is enough slack for the controller to fully extended out of the rack.
  • B Bypass the cable management arm and connect directly to the controller.
  • C Ensure that cables are pulled tight to dress it properly.
  • D Allow all cables to hang freely for more flexibility.
Explanation

Dell's official installation and storage expansion guides for PowerProtect DD systems (which apply to the DD9410/DD9910 platform and its ES40 expansion shelves) include a standard caution that when connecting SAS cables to the SAS cards, sufficient slack must be left in the cable. This prevents unnecessary strain on the cable connector and the SAS card itself when the controller is later fully extended out of the rack (for example, during servicing). Pulling cables tight, letting them hang freely, or bypassing the cable management arm would risk damaging the connectors or SAS card when the controller rails are extended.
