2.5-inch drive cable routing

See this topic to learn how to do cable routing for server models with 2.5-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 - 2.5-inch drive backplanes
From (backplane) to power distribution board		Length
`4` BP4	BP4 power connector	355mm
`3` BP3	BP3 power connector
`2` BP2	BP2 power connector	455mm
`1` BP1	BP1 power connector

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

Note

Depending on models, the server supports up to three 2.5-inch NVMe backplanes.
