LEDs inside the server on the system board; then, see the ProblemDetermination and Service Guide for information about how to solve theproblem.3. Remove the PCI-X riser-card assembly from the system board:a. If an adapter is installed in the riser-card assembly, disconnect any cablesthat are connected to the adapter.b. Grasp the riser-card assembly at the rear edge and lift it from the riser-cardconnector on the system board.c. Remove the adapter, if one is present, from the riser-card assembly.d. Store the riser-card assembly and the adapter in a safe place for possiblefuture use.4. Install a PCI Express adapter in the PCI Express riser-card assembly. See“Installing an adapter” on page 64 for more information. Set any jumpers orswitches on the adapter as directed by the adapter manufacturer.Note: You might have to replace the bracket when you replace a PCI-Xassembly with a PCI Express assembly.5. Insert the PCI Express riser-card assembly into the riser-card connector on thesystem board. Make sure that it is fully seated.If you have other devices to install or remove, do so now. Otherwise, go to“Completing the installation” on page 85.Replacing an IBM ServeRAID-BR10i SAS/SATA ControllerSome server models come with an IBM ServeRAID-BR10i SAS/SATA Controllerinstalled. The adapter can be installed only in the dedicated slot on the SAS/SATARAID riser-card assembly on the system board (see “System-board optional deviceconnectors” on page 46 for the location of the connector). Use the connector on theSAS/SATA RAID riser-card assembly for the RAID adapters. The IBMServeRAID-BR10i SAS/SATA adapter enables integrated RAID levels 0, 1, and 1Ecapability on hot-swap hard disk drives. For configuration information, see theServeRAID documentation at http://www.ibm.com/systems/support/. To install theadapter if your server model did not come with this adapter, complete the followingsteps to install an IBM ServeRAID-BR10i SAS/SATA adapter.Important: To ensure that any of your ServeRAID 10i, 10is, or 10M adaptersfunction properly on UEFI-based servers, make sure that the adapter firmware levelis updated to at least 11.x.x-XXX , and the supporting drivers.Attention: Some cluster solutions require specific code levels or coordinated codeupdates. If the device is part of a cluster solution, verify that the latest level of codeis supported for the cluster solution before you update the code.1. Read the safety information that begins on page vii and “Installation guidelines”on page 46.2. Turn off the server and peripheral devices and disconnect the power cords.Note: When you disconnect the power source from the server, you lose theability to view the LEDs because the LEDs are not lit when the powersource is removed. Before you disconnect the power source, make anote of which LEDs are lit, including the LEDs that are lit on theoperation information panel, on the light path diagnostics panel, and68 IBM System x3550 M2 Types 4198 and 7946: Installation and User’s Guide
