Before you begin, be sure you have: 
 o Reviewed the information given under Installing Internal Drives 
 o Removed the drive retainer (see step 1 of Installing Internal Drives) 
 o Chosen the bay into which you want to install the drive (see step 2 of Installing Internal Drives) 
 o Removed the hard disk drive assembly from bay 5, 6, or 7 if you are installing a new drive assembly in one of these bays (see steps 3 and 4 of Removing Internal Drives) 

   1. Find the bay in which you plan to install the drive assembly. 
      If a drive assembly is already installed in the bay you plan to use, remove the drive assembly as described in steps 3 and 4 of Removing Internal Drives. 
      Note:  The figures that accompany these steps show the installation occurring in bay 1.  These instructions also apply to bays 2 through 7. 

  2.  Prepare the bay for installation of the drive assembly: 
      a. Insert a small coin into the slot of the small knob located on the left-hand side of the bay.  (Do not use more than light pressure to do this! You can snap one "ear" off of the knob. Personal experience)
      b. Turn the knob clockwise, one-quarter (1/4) of the way. 
      c. Slide the knob to the left. 
      d. Continue with the next step. 

  3.  Install the hard disk drive assembly into the bay: 
      a. Position drive assembly so the connector is facing rear of server. 
      b. Align tray with guides, and slide the drive assembly into the bay. 
      c. Slide the knob to the right until it clicks into place.
