Hard Drive Backplane Overview

The hard drive backplane is housed in the hard drive cage. It provides data and
control signal connectors for the hard drives. It also provides the interconnect for the
front I/O board, power and locator buttons, and system/component status LEDs.
Note – Each drive has its own Power/Activity, Fault, and Ready-to-Remove LEDs.
