CAUTION: Disconnecting the RAID battery cable from a PERC card can cause
data loss if the "dirty cache" LED on the card is lit. The LED indicates that data is
still cached in controller memory and the data was not cleared at system
shutdown. Remove the RAID controller and raid battery as a set when the LED is
lit.
7
If removing a PERC RAID controller card, disconnect the RAID battery
cable from the expansion card.
NOTE: You must install a filler bracket over an empty expansion slot to
maintain Federal Communications Commission (FCC) certification of the
system. The brackets also keep dust and dirt out of the system and aid in
proper cooling and airflow inside the system.

Insert the filler bracket.
