1. Read the safety information that begins on page v and “Installation guidelines”on page 20.2. Turn off the server and peripheral devices, and disconnect the power cord andall external cables.3. Remove the filler panel from the empty drive bay.4. Pull the loops of the drive tray toward each other, and slide the drive into theserver until the drive connects to the backplate.5. Release the loops of the drive tray.6. Install the filler panel into the drive bay to cover the drive.Note: If the server has a RAID controller or adapter, you might have to reconfigurethe disk arrays after you install hard disk drives. See your RAID controller oradapter documentation.If you have other devices to install or remove, do so now. Otherwise, go to“Completing the installation” on page 38.Installing an adapterThe following notes describe the types of adapters that the server supports andother information that you must consider when you install an adapter:v Locate the documentation that comes with the adapter and follow thoseinstructions in addition to the instructions in this section. If you must change theswitch settings or jumper settings on the adapter, follow the instructions thatcome with the adapter.v The adapter slots are on the riser-card assemblies. You must first remove theriser-card assemblies to access the adapter slots.v The server provides two PCI Express slots on the riser-card assemblies andsupport half-length, full-height, PCI Express x8 1.0a adapters in each expansionslot.v The server scans the onboard SAS/SATA controller, PCI express slots 1 and 2,and onboard Ethernet controllers to assign system resources. Then, the serverstarts the devices in the following order, if you have not changed the defaultstartup sequence: PCI Express slot 1, then PCI Express slot 2.Note: You can change the sequence in which the server starts (boots) thedevices by using the Start Options menu choice from theConfiguration/Setup Utility program main menu. See “Using theConfiguration/Setup Utility program” on page 42 for detailed information.v For a list of supported optional devices for the server, see http://www.ibm.com/servers/eserver/serverproven/compat/us/.To install an adapter, complete the following steps:1. Read the safety information that begins on page v and the “Installationguidelines” on page 20.2. Turn off the server and peripheral devices and disconnect the power cords andall external cables. Remove the cover (see “Removing the server cover” onpage 23).28 IBM System x3350 Types 4192 and 4193: User’s Guide
