Cable routing for 2.5-inch drives

Follow the instructions in this section to learn how to do cable routing for 2.5-inch drives.

Go through the following list to acquire necessary information before starting cable routing for 2.5-inch drives.

Preliminary parts removal and installation​

  1. Make sure the following components are removed beforehand:

  2. Make sure to install all the drive backplanes that you plan to installed (see Install a drive backplane carrier assembly).

Power cables​

Connect power cables to drive backplanes as illustrated.

Figure 1. Drive backplane power cables


Table 1. Drive backplane power cables
1 Drive backplane 1 to connector 14 Drive backplane 4 to connector 4
2 Drive backplane 2 to connector 25 Drive backplane 5 to connector 5
3 Drive backplane 3 to connector 36 Drive backplane 6 to connector 6

Cable guides​

Make sure all the signal cables go through the cable guides on the system board and the memory expansion tray.

SAS/SATA cables for Gen3 and Gen4 RAID adapters​

When picking cables for 8i and 16i RAID adapters from SAS/SATA cable kits, make sure to choose the cables based on the generation of RAID adapters that you plan to install:
  • Gen3 RAID adapters (430-8i, 930-8i, 430-16i, 530-16i, 930-16i): MiniSAS to Slimline cable
  • Gen4 RAID adapters (940-8i, 940-16i): Slimline cable

Backplane and PCIe slot reference​

See the engraving on the cable connector for reference of PCIe slots to installed RAID adapters or PCIe switch cards in. For example, “BP 1/4” and “Slot 15/14 means the cable could be applied to the following scenarios:
  • Connecting backplane 1 to RAID adapter that is installed in slot 15
  • Connecting backplane 4 to RAID adapter that is installed in slot 14
