Installing the hard disk drive backplate

Use this information to install the hard disk drive backplate.

Before you install the hard disk drive backplate, complete the following steps:

1. Read Safety and Installation guidelines.
2. If the compute node is installed in a 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.
4. The default setting of 4 switches in SW1 are all “OFF”. Please make sure the switch-1 in SW1 is set to “ON” before you install the 4x2.5-inch hot-swap drive backplate as the following illustration.

To install the hard disk drive backplate, complete the following steps.

Figure 2. Installing backplate for 2.5-inch

Figure 3. Installing backplate for 1.8-inch

1. Remove the cover (see Removing the compute node cover).
2. Remove the hard disk drives (see Removing and installing drives).
3. Align the backplate with the hard disk drive cage and press the backplate into position.
4. Close the release latch.
5. Connect the power cable and signal cables to planar connectors or the RAID adapter.
6. Slide the hard disk drive into the bay until it is firmly seated in the connector.
7. For the 1.8-inch solid-state drives, lock the hard disk drive into place by closing the release lever.

After you install the hard disk drive backplate, 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).
