PCI riser-card assembly LEDsThe following illustration shows the light-emitting diodes (LEDs) on the PCIriser-card assembly.Note: Error LEDs remain lit only while the server is connected to power.Installation guidelinesUse the installation guidelines to install the System x3650 M3 Types 4255, 7945,and 7949Attention: 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 Read the safety information that begins on page “Safety” on page v, theguidelines in “Working inside the server with the power on” on page 39, and“Handling static-sensitive devices” on page 40. This information will help youwork 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 maximumlevels of performance. To download firmware updates for your server, completethe following steps:1. Go to http://www.ibm.com/systems/support/.2. Under Product support, click System x.3. Under Popular links, click Software and device drivers.4. Click System x3650 M3 to display the matrix of downloadable files for theserver.For additional information about tools for updating, managing, and deployingfirmware, see the System x and xSeries Tools Center at http://publib.boulder.ibm.com/infocenter/toolsctr/v1r0/index.jsp.v Before you install optional hardware, make sure that the server is workingcorrectly.
