   8. Insert the mini SAS cables or fabric cables.
   9. View the power and alarm indicators of the expansion module, and check whether the expansion module is successfully installed.
      • If the power indicator is steady on and the alarm indicator is off, the expansion module is successfully installed.
      • If the power indicator is off or the alarm indicator is on, the expansion module has not been installed properly. In this case, remove and reinsert the expansion module.

   Log in to the ISM and choose Event > Event Management. Click Events in the Event Management dialog box and select the device and event. Click Query to check whether Recovered At of the expansion module event is displayed.

   • If yes, no further action is required.
   • If no, go to step 2.

2. Collect related information and contact technical support engineers.
