Installing a P25 Node

Installing a P25 Node

Install a P25 into the cabinet. If disks are not installed in the P25 node, insert disks into the P25 node.


  • Operations described in Installing a Cabinet or Checking a Third-Party Cabinet have been completed.
  • Guide rails have been installed.
  • All required tools have been prepared, containing M3 to M6 Phillips screwdrivers, M6 screws, and protective gloves.


  • A fully configured P25 node weighs up to 35 kg. Therefore, arrange for at least three persons to carry it and ensure that they wear protective gloves to avoid personal injury.
  • Install components into a cabinet from bottom to top to prevent the cabinet from falling over.


  1. Install the P25 node into the cabinet.
    1. Wear the protective gloves.
    2. Slide the P25 node along the guide rail into the cabinet.
    3. Insert the screw into the floating nut through the screw hole on the P25 node and fasten the screw, as shown in Figure 8-60.

    4. Ensure that the P25 node sits properly and all bolts are fastened.


    If disks have not been installed into the storage nodes, install the disks after installing the storage nodes. If disks have been installed into the storage nodes, skip step 2.

  2. Optional: Install service disks.

    One SSD and 24 SAS disks are configured for the P25 node. The SSD is installed in slot 0 in the upper left corner of the front panel.

    1. Wear ESD gloves.
    2. Take the disks to be inserted out of the ESD bag.
    3. Raise the handle of the disk completely and push the disk straight into the slot with an appropriate amount of force, as shown in step 1 in Figure 8-61.

      • If the handle of the disk is not fully open, the disk cannot be completely inserted into the slot.
      • Excessive force may damage the disk connector.
      • To ensure favorable heat dissipation, insert disks in the sequence of disk slot IDs. If the disk module or PCIe module is not fully configured, cover filler panels over vacant disk slots or PCIe slots.
