CAUTION: See your System Information Guide for complete information about safety precautions, working inside the computer, and protecting
against electrostatic discharge.
NOTE: Keep this bracket in the event you need to remove the expansion card. Filler brackets must be installed over empty expansion card slots to
maintain Federal Communications Commission (FCC) certification of the system. The brackets also keep dust and dirt out of the system and help
keep the system properly cooled by promoting airflow inside the system.
NOTE: When you turn on the system, press the power button for less than two seconds. If you press the power button for longer than 3 seconds,
the NAS system shuts down and automatically rebuilds its RAID arrays, which could impact system performance for several hours.
