PCI riser-card adapter connectorsThe following illustration shows the connectors on the PCI riser cards foruser-installable PCI adapters.Slot 4 PCIe2 x8(8, 4, 1) Slot 1 PCIe2 x16(16, 8, 4, 1)Slot 2 PCIe2 x8(8, 4, 1)Slot 3 PCIe x4(8, 4, 1)Installation guidelinesAttention: Static electricity that is released to internal server components whenthe server is powered-on might cause the system to halt, which might result in theloss of data. To avoid this potential problem, always use an electrostatic-dischargewrist strap or other grounding system when removing or installing a hot-swapdevice.Before you install optional devices, read the following information:v Make sure that the devices that you are installing are supported. For a list ofsupported optional devices for the server, see http://www.ibm.com/systems/info/x86servers/serverproven/compat/us/.v Read the safety information that begins on page vii and “Handling static-sensitivedevices” on page 30. This information will help you work safely.v When you install your new server, take the opportunity to download and applythe most recent firmware updates. This step will help to ensure that any knownissues are addressed and that your server is ready to function at maximum levelsof performance. To download firmware updates for your server, go tohttp://www.ibm.com/support/fixcentral/.Important: Some cluster solutions require specific code levels or coordinatedcode updates. If the device is part of a cluster solution, verify that the latest levelof code is supported for the cluster solution before you update the code.For additional information about tools for updating, managing, and deployingfirmware, see the ToolsCenter for System x and BladeCenter athttp://publib.boulder.ibm.com/infocenter/toolsctr/v1r0/index.jsp.v Observe good housekeeping in the area where you are working. Place removedcovers and other parts in a safe place.v Do not attempt to lift an object that you think is too heavy for you. If you have tolift a heavy object, observe the following precautions:– Make sure that you can stand safely without slipping.– Distribute the weight of the object equally between your feet.– Use a slow lifting force. Never move suddenly or twist when you lift a heavyobject.– To avoid straining the muscles in your back, lift by standing or by pushing upwith your leg muscles.v Make sure that you have an adequate number of properly grounded electricaloutlets for the server, monitor, and other devices.28 IBM System x3755 M3 Type 7164: Installation and User’s Guide
