5 Connect the power/data cable to the back of the drive and to the system
board.
Route the cable properly inside the system to prevent it from being
pinched or crimped. For more information, see "Front-Chassis Assembly"
on page 90.
6 Close the system. See "Closing the System" on page 77.
7 Reconnect the system to its electrical outlet and turn the system on,
including any attached peripherals.
8 If applicable, replace the front bezel. See "Installing the Front Bezel" on
page 75.
Power Supplies
Your system supports two hot-swappable 1100 W power supplies.
If two power supplies are installed, the second power supply provides, power
redundancy. In a redundant mode, the system distributes the power load
across both power supplies to maximize efficiency. When a power supply is
removed with the system powered on, the full power load is picked up by the
second power supply. Table 3-1 lists the power supply redundancy modes.
