C-192T, C-432T, and K-432T NIC Field Replacement Unit

IN THIS ARTICLE

This article explains how to replace an NIC on C-192T, C-432T, and K-432T nodes.

Notes: These node types use multiple NIC vendors. This doesn't affect performance and, if the NIC fails, you should replace it with the same vendor model.

IDENTIFYING THE NICs IN YOUR NODES

Identifying NICs differs depending on your cluster type:

  • For clusters connected to Cloud-Based Monitoring, Qumulo Care can view the NIC vendor in use and can ensure that you receive the correct replacement part.
  • For dark-site clusters, you must verify the NIC model in use and inform Qumulo Care to ensure that you receive the correct replacement:
    • If your node is online, use SSH to connect to it and then run the lspci | grep "Ethernet controller" command. The following is example output:
      01:00.0 Ethernet controller: Broadcom Inc. and subsidiaries BCM57414 NetXtreme-E 10Gb/25Gb RDMA Ethernet Controller (rev 01)
      01:00.1 Ethernet controller: Broadcom Inc. and subsidiaries BCM57414 NetXtreme-E 10Gb/25Gb RDMA Ethernet Controller (rev 01)
      41:00.0 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01)
      41:00.1 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01)
    • If your node is offline, but the BMC is still operational, log in to the BMC and identify the hardware part in use.
      1. On the left-hand navigation bar, click System Inventory.
      2. On the top navigation bar, click PCIe & OCP Card.
    • If your node is offline but the BMC is unavailable, you must identify the vendor specified on the NIC inside your node.

PROCESS

To Remove the Existing NIC

  1. Power down the node and disconnect all cabling from it.

  2. Loosen the two black thumbscrews on the front of the node and pull the node out of the rack.
  3. To remove the top panel, press the blue button and slide the panel towards the back of the node.

  4. Locate the NIC in the middle of the PCI card cage and remove the screw from the NIC.

  5. Gently lift the NIC upwards.

To Install the Replacement NIC

  1. Install the replacement NIC and secure it with the screw.
  2. Install the node back into the rack.
  3. Tighten the two black screws.
  4. Reconnect all cabling to the node.
  5. Power up the node.
