Road map for installing the 5094, 5294, 5096, and 5296 expansion units

To install the 5094, 5294, 5096, and 5296 expansion units, you must perform the following tasks. These tasks are arranged in a series of chronological steps for installing your expansion unit. Where appropriate links are available to provide you with additional detail related to performing these tasks. At the completion of each task, return to this road map for guidance related to performing the next task.

1. Unpack the expansion unit.
2. Complete a parts inventory. For details, see Completing a parts inventory.
3. Cable the expansion unit to the server:
   Note:

   • This unit uses remote input/output (RIO) and system power control network (SPCN) cables to connect to the server.
   • You may need to power off the server before connecting the cables.
   • Do not perform remote input/output and high-speed Link (RIO/HSL) configuration changes, such as moving existing expansion units to different GX adapters, at the same time you add new expansion units.
   • If you are adding a new expansion unit or migrating expansion units from another IBM® POWER® server, you may not be able to allocate the expansion unit resources to logical partitions on the new server until an SPCN firmware update is completed for the expansion units.
   • For detailed procedures related to preparing to connect your expansion units, see Prepare to connect your expansion units and perform all applicable prerequisites for installing your expansion units.
   • For a detailed procedure that helps you connect your expansion units to the system, see Connect your expansion units.
4. Connect power cables and apply power.
5. Verify that the SPCN is functioning correctly. For details, see Verify the System Power Control Network.
6. Verify that the new expansion unit configuration is functioning properly. For details, see Verify that the new configuration is functioning.
