2.5-inch drive backplane cable routing

Connect power cable and signal cables to the 2.5-inch drive backplane according to the corresponding sections:

• 2.5-inch drive backplane power cable routing
• 2.5-inch drive backplane signal cable routing

According to the configuration of front riser assemblies, see the corresponding section for the 2.5-inch drive power cable routing:

• Front riser assemblies x8/x8/x8/x8 configuration
• Front riser assemblies x16/x16 configuration (supporting DW GPU adapters)
