Installing the optional 3.5-inch hard disk drive hardware RAID cage

Use this information to install the optional 3.5-inch hard disk drive hardware RAID cage.

Before you install the hard disk drive cage, complete the following steps:
  1. Read Safety and Installation guidelines.
  2. If the compute node is installed in an Lenovo NeXtScale n1200 Enclosure, remove it (see Removing a compute node from a chassis for instructions).
  3. Carefully lay the compute node on a flat, static-protective surface, orienting the compute node with the bezel pointing toward you.

To install the optional 3.5-inch hard disk drive hardware RAID cage, complete the following steps.

  1. Remove the cover (see Removing the compute node cover).
  2. Position the hardware RAID cage in the bezel at an angle and rotate the cage into position on the system board.
  3. Align the cage with the screw holes on the system board.
  4. Using a Phillips screwdriver, insert the 4 screws and secure the cage in the compute node.
  5. Install the easy-swap hard disk drive #7 (see Installing a 3.5-inch hard disk drive).
  6. Connect the power cable and the mini-SAS cable on the system-board and the storage tray respectively (see Cabling hard disk drive with ServeRAID SAS/SATA controller).

After you install the hard disk drive cage, complete the following steps:
  1. Install the cover onto the compute node (see Installing the compute node cover for instructions).
  2. Install the compute node into the chassis (see Installing a compute node in a chassis for instructions).
