Chapter 3 Maintaining the Server
Installing or Replacing Components
Replacement Procedure
Installing a PCIe card requires that you first remove the riser card assembly from the chassis. To install
or replace a PCIe card, follow these steps:
Step 1 Remove a PCIe card:
a.
Power off the server as described in the “Shutting Down and Powering Off the Server” section on
page 3-9 .
b. Disconnect all power cords from the power supplies.
c.
Slide the server out the front of the rack far enough so that you can remove the top cover. You might
have to detach cables from the rear panel to provide clearance.
Caution
If you cannot safely view and access the component, remove the server from the rack.
d. Remove the top cover as described in the “Removing and Replacing the Server Top Cover” section
on page 3-10 .
e.
Remove the riser card retaining plate by loosening the two captive thumbscrews, then lift the plate
out of the chassis.
f.
Lift the riser card assembly and any attached PCIe cards straight up and out of the chassis. Lift up
on both ends of the assembly evenly to avoid damaging the sockets or the riser cards.
g.
Remove the screw that secures the PCIe card rear plate to the assembly rear opening and disconnect
any cables attached to the card (see
Figure 3-18 ).
h. Pull the PCIe card connector out of the riser card socket and set the card aside.
Step 2
Install a PCIe card:
a. If you are installing a PCIe card to an empty slot on the riser card assembly, remove any blank panel
from the assembly rear opening by removing the screw that secures the panel. Set the screw aside.
Note A standard-profile PCIe card must be installed in the right-hand riser card assembly, as viewed
from the rear of the server. A low-profile PCIe card can be installed in either the low-profile
assembly on the left, or the standard-profile assembly on the right if a standard-profile I/O
bracket is used on the card.
b. Align the PCIe card connector with the riser card socket and push on both ends of the card evenly
to fully engage the connector with the riser card socket.
c.
Install the screw that secures the rear plate of the card to the assembly rear opening.
d.
Set the assembly in place, aligning the riser card connector with the socket on the motherboard.
e.
Press down evenly on both ends of the assembly to fully engage the riser cards with the sockets on
the motherboard.
f. Replace the riser card retaining plate. Align the pegs on the plate with both riser card assemblies,
then tighten the captive thumbscrews on the plate.
g.
Replace the top cover.
h. Replace the server in the rack, replace power cords and any other cables, and then power on the
server by pressing the
Power button.
