Remove a rear riser assembly

Follow instructions in this section to remove a rear riser assembly.

About this task

The server supports different types of riser cages (see Table 1). This topic uses the 3FH riser 1 cage and Gen 4 riser 3 cage as an example for illustration. The replacement procedure is the same for other riser cages.

Attention

  • Read Installation Guidelines and Safety inspection checklist to ensure that you work safely.

  • Power off the server and peripheral devices and disconnect the power cords and all external cables. See Power off the server.

  • Prevent exposure to static electricity, which might lead to system halt and loss of data, by keeping static-sensitive components in their static-protective packages until installation, and handling these devices with an electrostatic-discharge wrist strap or other grounding system.

  • Before you remove any component of a RAID array (drive, RAID card, etc.), back up all RAID configuration information.

Procedure

  1. Make preparation for the task.
    1. If the server is installed in a rack, slide the server out on its rack slide rails to gain access to the top cover, or remove the server from the rack. See Remove the server from rack.
    2. Remove the top cover. See Remove the top cover.
    3. If there is any PCIe adapter installed on the riser card, record the cable connections first. Then, disconnect all cables from the PCIe adapter.
  2. Remove the riser assembly.

    • Riser 1 assembly (same for riser 2 assembly)

      Note

      The following uses the 3-slot riser cage as an example for illustration. The replacement procedure for the 1-slot riser cage is similar.
