Hard Disk Drive Activity Light Does Not Light If you have installed one or more hard disk drives in your system, check the following: YAre the power and signal cables to the drive properly installed? YAre all relevant switches and jumpers on the hard drive and adapter board set correctly? YIs the onboard IDE controller enabled? (IDE hard drives only) YIs the hard disk drive properly configured? NOTE Front panel hard disk LED indicates IDE and SCSI devices: the hard disk drive activity light on the front panel lights when either an IDE hard disk drive, or a SCSI device controlled by the onboard SCSI host controller, is in use. This LED does not display CD-ROM activity. CD-ROM Drive Activity Light Does Not Light Check the following: YAre the power and signal cables to the CD-ROM drive properly installed? YAre all relevant switches and jumpers on the drive set correctly? YIs the drive properly configured? YIs the onboard IDE controller enabled? NOTE Front panel hard disk LED indicates IDE and SCSI devices: the hard disk drive activity light on the front panel lights when either an IDE hard disk drive, or a SCSI device controlled by the onboard SCSI host controller, is in use. This LED does not display CD-ROM activity. Network Problems If you have network problems, consult the documentation that came with the network board you purchased for this server. PCI Installation Tips YSome common PCI tips are listed here. Reserve interrupts (IRQs) and/or memory addresses specifically for ISA adapters. This prevents PCI boards from trying to use the same settings ISA boards are using. Use the SSU Yto keep track of ISA adapter resources. Certain drivers may require interrupts that are not shared with other PCI drivers. The SSU can be used to adjust the interrupt numbers for PCI devices. For certain drivers, it may be Ynecessary to alter settings so that interrupts are not shared. Check PCI interrupt interdependencies among slots and onboard devices. 129
