Replacing an adapter/GPU adapter
The following notes describe the types of adapters that the server supports and other information that
you must consider when you install an adapter.
Before you install an adapter/GPU adapter, 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.
• Locate the documentation that comes with the adapter and follow those instructions in addition to
the instructions in this section.
• For configuration information, see the ServeRAID documentation at http://www.lenovo.com/support.
• When you install any PCI adapter, the power cords must be disconnected from the power source before
you remove the PCI Express riser-cage assembly. Otherwise, the active power management event signal
will be disabled by the system-board logic, and the Wake on LAN feature might not work. However, after
the server is powered-on locally, the active power manager active power management event signal will
be enabled by the system-board logic.
To install an adapter/GPU adapter, complete the following steps:
Note: If your adapter was previously configured, backup or record its configuration information, if possible,
before replacing the adapter. See the documentation for your adapter for information and instructions.
Step 1. Remove the cover (see “Removing the compute node cover” on page 113).
Step 2. Follow the cabling instructions, if any come with the adapter/GPU adapter. Route the adapter
cables before you install the adapter/GPU adapter.
Step 3. Insert the adapter/GPU adapter into the PCI riser-cage assembly, aligning the edge connector on
the adapter/GPU adapter with the connector on the PCI riser-cage assembly. Press the edge of
the connector
firmly into the PCI riser-cage assembly. Make sure that the adapter/GPU adapter
snaps into the PCI riser-cage assembly securely.
