3. Backplane and Server Board Overview

Each drive tray includes two LED indicators for drive activity and drive status. Operators can observe the system status from the
front panel, as light pipes integrated into the drive tray directly light emitted from LEDs which are mounted on the backplane to
the drive tray faceplate.

different from what is described in the above table. If the activity LED on a given drive type behaves differently than what is
