Backplanes: server models with 2.5-inch front drive bays

This section provides backplane cable connection information for server models with 2.5-inch front drive bays.

Before you start​

Ensure below parts are removed before starting cable routing for front backplanes.

Power cable connections​

The server supports the following 2.5-inch drive backplanes:

  • 8 x 2.5-inch SAS/SATA backplane

  • 8 x 2.5-inch AnyBay backplane (also used as an 8 x 2.5-inch NVMe backplane when only NVMe connectors on the backplane are cabled)

  • 24 x 2.5-inch SAS/SATA expander backplane

For connectors on each drive backplane, see Drive backplane connectors.
