Replacing Hardware Components in Your Fsas Technologies PRIMERGY RX2540 M7 Nodes

This section explains how to replace hardware components in Fsas Technologies PRIMERGY RX2540 M7 nodes.

Caution

We strongly recommend engaging an on-site engineer to replace failed hardware components including but not limited to any procedure that:
- This guide doesn't cover
- You haven't received training on
- Requires precautions to avoid damage caused by electrostatic discharge (ESD) by using industry standard anti-static equipment (such as gloves or wrist straps)
We don’t recommend updating firmware on Qumulo-certified hardware nodes unless the equipment manufacturer or a member of the Qumulo Care team advises you to do so. For questions about this process, contact the Qumulo Care team.

Removing and Replacing the Top Cover

Follow the instructions in the Fsas Technologies Upgrade and Maintenance Manual: Removing the top covers (p. 58).

Replacing an NIC

Your Fsas Technologies RX2540 M7 chassis contains two horizontal PCIe riser modules and a NIC inserted horizontally into the bottom module.

Follow the instructions in the Fsas Technologies Upgrade and Maintenance Manual: Removing an expansion card from a riser module (p. 317).

Replacing a RAID Module Riser

Your Fsas Technologies RX2540 M7 chassis contains two RAID riser modules (for the two mirrored boot drives) inserted horizontally into the motherboard. Each riser module holds an interposer (controller) board.

Follow the instructions in the Fsas Technologies Upgrade and Maintenance Manual: Handling riser modules (p. 72).

Replacing an Interposer (Controller) Board

Each of the two RAID module risers on your chassis contains an interposer (controller) board which, in turn, holds an M.2 boot drive.

Follow the instructions in the Fsas Technologies Upgrade and Maintenance Manual: Removing the M.2 interposer board (p. 222).

To Replace an M.2 Boot Drive

Your Fsas Technologies RX2540 M7 chassis contains two mirrored NVMe boot drives, each of which is inserted into an interposer (controller) board.

To replace this component, you must first power off the node.
Remove the RAID module riser from the motherboard.
Follow the instructions in the Fsas Technologies Upgrade and Maintenance Manual:
1. Remove the M.2 SSD (p. 216).
2. Install an M.2 SSD (p. 212).

Initializing the Replacement Boot Drive

After you replace the boot drive, you must initialize the replacement boot drive by using the Qumulo Core Installer and then rebuild the replacement boot drive by using a script on the node in your cluster.

Step 1: Initialize the Replacement Boot Drive

Tip
To get the correct version of the Qumulo Core Installer for the node in your cluster, contact the Qumulo Care team

Create a Qumulo Core USB Drive Installer.
Power on your node, enter the boot menu, and select your USB drive.

The Qumulo Core Installer begins to run automatically.
When prompted, take the following steps:
1. Select [x] Perform maintenance.
2. Select [1] Boot drive reset and then follow the prompts.
The Qumulo Core Installer initializes the boot drive.
When the process is complete, the node is powered down automatically.

Step 2: Rebuild the Replacement Boot Drive

Power on your node and log in to the node by using the qq CLI.
To get root privileges, run the sudo qsh command.
To stop the Qumulo Networking Services, run the service qumulo-networking stop command.
To configure the IP address for the node, run the ip addr add command and specify the node’s IP address. For example:
```
ip addr add 203.0.113.0/CDR dev bond0
```
Ensure that the node can ping other nodes in the cluster.
Run the rebuild_boot_drive.py script and specify the IP address of another node in the cluster, the ID of the node whose boot drive has been replaced, and the password of the administrative account of the cluster. For example:

Note
If your password includes special characters such as the parenthesis (() or the asterisk (*), use the backslash (\) to escape these characters.
```
/opt/qumulo/rebuild_boot_drive.py \
  --address 203.0.113.1 \
  --node-id 2 \
  --username admin \
  --password my\(Special\*Password
```
Follow the prompts.
When the process is complete, reboot the node.

Replacing an HDD

Your Fsas Technologies RX2540 M7 chassis contains 12 or 8 HDDs. For more information, see HDD Drives.

Note
You can replace this component without powering off the node.

Follow the instructions in the Fsas Technologies Upgrade and Maintenance Manual: Installing 3.5-inch HDD modules (p. 150).

Replacing an NVMe Drive

Your Fsas Technologies RX2540 M7 chassis contains 4 NVMe drives in cages 1 (left) and 2 (middle) at the back of the node. For more information, see NVMe Drives.

Follow the instructions in the Fsas Technologies Upgrade and Maintenance Manual: Rear HDD/SSD extension box (p. 227).

Replacing a Power Supply Unit (PSU)

Your Fsas Technologies RX2540 M7 chassis contains two PSUs.

Note
You can replace this component without powering off the node.

Follow the instructions in the Fsas Technologies Upgrade and Maintenance Manual: Installing a hot-plug PSU (p. 126).

Replacing a Fan Module

Your Fsas Technologies RX2540 M7 chassis has 6 fan modules.

Follow the instructions in the Fsas Technologies Upgrade and Maintenance Manual: Handling the fan cage (p. 76).

To Replace a DIMM

Your Fsas Technologies RX2540 M7 chassis has 12 DIMM slots, with a locking latch on each side of each DIMM.

To replace this component, you must first power off the node.
Follow the instructions in the Fsas Technologies Upgrade and Maintenance Manual: Installing the memory modules (p. 345).
