3.5-inch drive cable routing

See this topic to learn how to do cable routing for server models with 3.5-inch drive backplanes.

Complete the following routing for power cables corresponding to the backplanes that are installed in the system.
Table 1. Power cable routing - 3.5-inch drive backplanes


From (backplane) to power distribution boardLength
4 BP4BP4 power connector

160 mm

3 BP3BP3 power connector

355 mm

2 BP2BP2 power connector
1 BP1BP1 power connector

455 mm

Then, proceed to the table of combinations that correspond to the system configuration:

Note
* Depending on the configurations, the server might come with either the 3.5-inch BP4 or the ODD/Tape drive cage.
  1. For server models with the 3.5-inch BP4, there is no ODD/Tape drive cage.

  2. For server models with the ODD/Tape drive cage, there is no 3.5-inch BP4.

See Front view for different sever models.
