Installing System Components 121
  NOTE: Before installing any expansion cards, see "Expansion Card Installation 
Guidelines."
 
NOTE: The procedure for installing expansion cards into risers 1 and 2 is the same 
except that slots 3 and 4 on riser 2 have card-edge guides for installing 24.13-cm 
(9.5-in)
 expansion cards.
1
Unpack the expansion card and prepare it for installation.
For instructions, see the documentation accompanying the card.
2
Turn off the system, including any attached peripherals, and disconnect 
the system from the electrical outlet.
3
Open the system. See "Opening the System."
4
Open the expansion-card guide latch and remove the filler bracket at the 
back of the system. See Figure 3-26. 
  NOTE: Keep this bracket in case you need to remove the expansion card. 
Filler brackets must be installed over empty expansion-card slots to maintain 
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.
5
Install the expansion card: 
a
If the expansion card is 24.13 cm (9.5 in), align its front edge with the 
front card guide. See Figure 3-26.
b
Position the expansion card so that the card-edge connector aligns 
with the expansion-card connector on the expansion-card riser board.
c
Insert the card-edge connector firmly into the PCIe card connector 
until the card is fully seated.
d
When the card is seated in the connector, close the expansion-card 
latch. See Figure 3-26.
6
Connect any expansion-card cables for the new card.
See the documentation that came with the card for information about its 
cable connections.
7
Close the system. See "Closing the System."
8
Reconnect your system and peripherals to their electrical outlets, and turn 
on the system.
