This section explains how to replace hardware components in Supermicro 1114S nodes.

To Perform the Part Replacement Procedure by Using the FVT

When you replace a component such as the motherboard or a NIC card in your node, you must ensure that the firmware version and configuration are correct for your new components. To do this, you must perform the part replacement procedure by using the FVT.

  1. Boot by using the latest version of the Qumulo Core USB Drive Installer.

  2. Select [*] Perform maintenance.

  3. Select [2] Perform automatic repair after part replacement (non-destructive).

    The part replacement procedure runs and the FVT passed! message appears.

To Replace a Drive

The ten hot-swap drive carriers are located at the front of your Supermicro 1114S chassis. The boot drive is located in the internal M.2 expansion slot.

Replacement drives, including the on-site spare drives that you received with your original nodes, are provided without a drive carrier. When replacing a faulty drive, you must remove the existing drive from its carrier and then insert the new drive into the carriers. The drive carriers are toolless and don’t require any screws.

  1. Locate the drive that requires replacement by using the drive bay mapping.

  2. To remove the existing drive:

    1. Press the orange release button on the right of the drive carrier until the drive carrier handle extends on the left.

    2. Use the drive carrier handle to pull the carrier out of the chassis.

    3. To remove the drive from the carrier, undo the mounting clips.

  3. To install a replacement drive:

    1. Insert the new drive into the drive carrier with the printed circuit board (PCB) side facing down and the connector end facing towards the rear of the tray.

    2. Secure the drive to its carrier by using the mounting clips.

    3. Insert the drive carrier into the chassis with the orange release button facing right.

    4. Push the drive carrier into the chassis until the handle retracts and clicks into place.

To Replace a Power Supply Unit (PSU)

The two hot-swap PSUs are located at the front of your Supermicro 1114S chassis. If either of the two PSUs fails, the other PSU takes on the full load and lets the node continue operating without interruption.

When a PSU fails, the Info LED at the front of the node begins to blink red every four seconds. In addition, the failure LED on the PSU at the back of the node lights up.

  1. To determine which PSU failed, check the PSU LED.

  2. Disconnect the power cord from the existing PSU.

  3. To remove the existing PSU, press the purple release tab to the left while pulling on the handle.

  4. Insert the new PSU and push it into the chassis until it clicks into place.

  5. Connect the power cord to the new PSU.

To Replace a Fan

Your Supermicro 1114S chassis has six internal fans. When a fan fails, the Info LED at the front of the node begins to blink red every second.

  1. Power off the node, remove the top chassis cover, and disconnect the power cords from both PSUs.

  2. Disconnect the existing fan housing cable from the motherboard and remove the fan housing from its two mounting posts.

  3. Insert a new fan provided by Supermicro into the housing, making sure that the airflow direction arrows on top of the fan face the same direction as the arrows on the other fans.

  4. Reposition the fan housing over the two mounting posts and connect the fan housing cable to the motherboard.

  5. Power on the node and confirm that the new fan is working properly and the Info LED has stopped blinking red.

  6. Install the top chassis cover.

To Replace a DIMM

Your Supermicro 1114S chassis has 16 DIMM slots (8 × 16 GB DIMMs for a total 128 GB of memory).

To identify which DIMM failed, you must use the baseboard management controller (BMC) on the node or another hardware monitoring solution.

  1. Power off the node, remove the top chassis cover, and disconnect the power cords from both PSUs.

  2. Remove the existing DIMM.

    The following is the DIMM slot mapping. In this diagram, the CPU socket mounting bracket and power headers are at the bottom.

  3. To remove the existing DIMM, press both DIMM slot release tabs outwards. When the module is loose, remove it from the slot.

  4. To insert a new DIMM, align the keyed notch on the DIMM with the receptive points on the DIMM slot.

  5. Push in both ends of the DIMM straight down until it clicks into place.

  6. Press both DIMM slot release tabs inwards.

  7. Install the top chassis cover.

  8. Power on the node.
