Install a 2.5-inch drive backplane

Follow instruction in this section to install a 2.5-inch drive backplane.

About this task

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.

  • If the server is installed in a rack, slide the server out on its rack slide rails to gain access to the top covers, or remove the server from the rack. See Remove the server from rails.

The server supports up to six drive backplanes with the following corresponding drive bay numbers.

Note
When ThinkSystem 256GB TruDDR5 4800MHz (8Rx4) 3DS RDIMM v1 is installed in the system, the maximum number of supported drives is twenty-four drives.

After you finish

  1. Reinstall the drive backplane carrier. See Install the drive backplane carrier assembly.

  2. Connect the power and signal cables to all the backplanes. See 2.5-inch drive backplane cable routing for more information on the internal cable routing.

  3. Reinstall all the 2.5-inch hot-swap drive and drive fillers. See Install a 2.5-inch hot-swap drive.

  4. Reinstall the fan cage. See Install the fan cage.

  5. Reinstall all fan modules. See Install a fan module.

  6. Reinstall the front air baffle. See Install the front air baffle.

  7. Reinstall the front top cover. See Install the front top cover.

  8. Complete the parts replacement. See Complete the parts replacement.

  9. If you have installed 2.5-inch drive backplane with U.3 NVMe drives for Trimode. Enable U.3 x1 mode for the selected drive slots on the backplane through the XCC web GUI. See U.3 NVMe drive can be detected in NVMe connection, but cannot be detected in Tri-mode.
