2.3 HDD Tray
The HDD tray houses the HDD bay and various other components. All components other
than the HDD bay require the full extension of the HDD tray before servicing.
The Power Distribution Board (PDB) remains fully engagaed and the system continues to
draw even when the HDD tray is extended to an open position. Only by disconnecting the
power cord from the power supply unit is the system powered down.
The hot-plug HDDs can be serviced without removing the system from the rack:
All other component servicing require the system to be removed from the rack and placed
on a stable, clean flat surface.
