Installing a P25E Node

Installing a P25E Node

Installing a P25E node into the cabinet includes sliding the P25E node into the cabinet, fastening the P25E node, and checking the installation result.


  • Operations described in Installing a Cabinet or Checking a Third-Party Cabinet has been completed.
  • Holding rails have been installed.
  • All required tools have been prepared, containing M3 to M6 Phillips screwdrivers, M6 screws, and protective gloves.
  • Ensure that the CPU, DIMM, riser card, the PCIe card on the riser card, and the PCIe card of the node are installed. If any of the parts is not installed, see section "Replacing Components for a P12E or P25E Node" in Parts Replacement to install it.


  • A P25E that is in the maximum configuration weighs up to 30 kg. Arrange at least two 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 a P25E.
    1. Pull out the P25E as shown in Figure 8-30.

  2. Optional: Install hard disks.

    1. Fully raise the ejector lever and push the hard disk into the chassis along the guide rails until it does not move. See step 1 in Figure 8-32.

      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.
