Guideline for cable routing for 2.5-inch drives

General guideline for cable routing for 2.5-inch drives.

  1. Make sure all the signal cables go through the cable guides.

    Figure 1. Cable guide locations

  2. If the processor and memory expansion tray is installed in the server, lift the tray and route the direct NVMe signal cables in the cable guide and behind the tray.
    Figure 2. Routing the NVMe cables to the processor and memory expansion tray


    Connect the direct NVMe signal cables to the NVMe connectors on the processor and memory expansion tray.

    Figure 3. Connecting the NVMe cables to the processor and memory expansion tray


Before starting cable routing for 2.5-inch drives:

  1. Remove the fan cage assembly (see Remove the fan cage assembly).

  2. Remove the system board air baffle (see Remove the system board air baffle and the power interposer) or the processor and memory expansion tray and the processor and memory expansion tray air baffle (see Remove the processor and memory expansion tray).

Connecting power cable​

Connect power cables for drive backplanes as in the following illustration.

Two types of drive backplanes are supported by this system:
  • 2.5-inch SATA/SAS 8-bay backplane (referred to as “8-bay backplane”)
  • 2.5-inch AnyBay 8-bay backplane (referred to as “AnyBay backplane”)

4U PCIe riser assemblies can be installed when the PCIe slot 3 or 13 are not occupied by PCIe adapters, make sure the slots for 4U PCIe riser cards are available before the riser card installation.
