CD-ROM Drive Activity Light Does Not Light
Check the following:
❑ Are the power and signal cables to the CD-ROM drive properly installed?
❑ Are all relevant switches and jumpers on the drive set correctly?
❑ Is the drive properly configured?
❑ Is 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
Some common PCI tips are listed here.
• Reserve interrupts (IRQs) and/or memory addresses specifically for ISA adapters.
This prevents PCIboards from trying to use the same settings ISA boards are using.
Use the SSU to 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 necessary to alter settings so that interrupts are not shared.
• Check PCI interrupt interdependencies among slots and onboard devices.
