procedure, review the safety instructions that came with the system.

from its electrical outlet.
6 Open the system. See "Opening the System" on page 85.
7 Ensure that the controller card is firmly seated into the system board
connector. See "Integrated Storage Controller Card" on page 132.
8 If you have a battery-cached PERC controller, ensure that the RAID
battery is properly connected and, if applicable, the memory module on
the PERC card is properly seated.
9 Verify that the cable connections between the SAS backplane and the
integrated storage controller are correct. See "Installing an Integrated
Storage Controller Card" on page 134.
Ensure that the cables are firmly connected to the storage controller and
the SAS backplane board.
10 Close the system. See "Closing the System" on page 86.
11 Place the system upright and on its feet on a flat and stable surface,
reconnect the system to the electrical outlet, and turn on the system and
attached peripherals.
If the problem persists, see "Getting Help" on page 193.
