Lenovo NeXtScale nx360 M5 Compute Node - Removing a PCI riser-cage assembly from the 2U GPU tray

Before you remove a PCI riser-cage assembly from the 2U GPU tray, complete the following steps:

Read Safety and Installation guidelines.
If the compute node is installed in a NeXtScale n1200 Enclosure, remove it (see Removing a compute node from a chassis for instructions).
Carefully lay the compute node on a flat, static-protective surface, orienting the compute node with the bezel pointing toward you.

Note: PCI riser-cage brackets must be installed even if you do not install a GPU adapter.

To remove a PCI riser-cage assembly from the 2U GPU tray, complete the following steps:

Remove the cover (see Removing the compute node cover).
Pull up the release handle from the PCI riser assembly.
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 2U GPU tray; then lift it out of the PCI riser-cage out of the 2U GPU tray.

If a GPU adapter is installed in the PCI riser-cage assembly, disconnect any cables that are connected to the adapter.
Remove the GPU adapter, if one is present, from the PCI riser-cage assembly (see Removing an adapter/GPU adapter).
Set the GPU adapter and the PCI riser-cage assembly aside.
Remove the 2U GPU tray from the compute node (see Removing a 2U GPU tray from a compute node).
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.
