Installing PCIe Riser Version 2B For NVMe SFF 2.5-Inch SSDs
PCIe Riser Version 2B (UCSC-PCI-2B-220M4) has two cable connectors that are used to provide
communication from the front-panel drive bays to the PCIe bus.

Step 1
Remove an existing PCIe riser assembly that you are replacing:
a.
Power off the server as described in
Shutting Down and Powering Off the Server, page 3-8
b.
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.
c.
Remove the top cover as described in
Removing and Replacing the Server Top Cover, page 3-9
.
d.
Use two hands to grasp the metal bracket of the riser assembly and lift straight up to disengage its
connectors from the two sockets on the motherboard.
e.
If the riser has any cards installed, remove them from the riser.
Step 2
Install a new PCIe riser assembly Version 2B:
a.
If you removed any cards from the old riser assembly, install the cards to the new riser assembly (see
Replacing a PCIe Card, page 3-50
).
b.
Position the riser assembly over its two sockets on the motherboard and over the chassis alignment
channels (see
c.
Carefully push down on both ends of the riser assembly to fully engage its connectors with the two
sockets on the motherboard.
Step 3
Connect the two cables that come with UCSC-PCI-2B-220M4:
a.
Connect both cable connectors to the two connectors on the riser 2B (see
).
b.
Route the cables to the front of the server using the recommended path through the chassis cable
guides as shown in
