Caution: Use caution when working around the hard drive backplane. Do not touch
the backplane with any metal objects and make sure no cables touch the backplane.
Also, regardless of how many drives are installed, all twelve drive carriers must remain
in the chassis to maintain proper airfl ow.
Caution: Be aware that powering down a node will power down all the hard drives
that are logically associated with it (as shown in Figure 6-18).

The SC217HDHD chassis contains two individual motherboards in separate node
drawers. Each motherboard node controls a set of six hard drives. Note that if a
motherboard node drawer is pulled out of the chassis, the hard drives associated
with that node will power down as well. See the table below for details.
