Step 2.
Grasp the rear side of the PCI riser-cage touch point and the front PCI rise-cage suitable location
of the PCI riser-cage assembly. Use your thumb to press down the right hand side bezel (a tiny
square surface) of the compute node; then lift it out of the PCI riser-cage slot on the system board.

Step 3.
If an adapter is installed in the PCI riser-cage assembly, disconnect any cables that are connected
to the adapter.
Step 4.
Remove the adapter, if one is present, from the PCI riser-cage assembly (see "Removing an
adapter/GPU adapter" on page 184).
Step 5.
Set the adapter and the PCI riser-cage assembly aside.
Step 6.
If you are instructed to return the PCI riser-cage assembly, follow all packaging instructions, and
use any packaging materials for shipping that are supplied to you.
Replacing a PCI riser-cage assembly
Before you install a PCI riser-cage assembly, complete the following steps:
1. Read "Safety" on page v and "Installation guidelines" on page 101.
2. If the compute node is installed in a NeXtScale n1200 Enclosure, remove it (see "Removing a compute
node from a chassis" on page 104 for instructions).
3. Carefully lay the compute node on a flat, static-protective surface, orienting the compute node with
the bezel pointing toward you.
Notes:
1. PCI riser-cage brackets must be installed even if you do not install an adapter.
2. There must be either a DIMM or DIMM filler installed for all 16 DIMM slots.
To install a PCI riser-cage assembly, complete the following steps:
Step 1.
Remove the cover (see "Removing the compute node cover" on page 113).
Step 2.
Remove the PCI filler panel, if one is present, from the front of the server.
Step 3.
Align the PCI riser-cage assembly with the PCI riser connector on the system board; then, grasp
the rear side of the PCI riser-cage touch point and the front PCI rise- cage suitable location of
the PCI riser-cage assembly.
Step 4.
Press down firmly until the PCI riser-cage assembly is seated correctly in the connector on the
system board.
