z NIC1: Indicates network activity on LAN1 when flashing.
z HDD: Indicates IDE channel activity. On the SuperServer 6034H-X8R,
this LED indicates SCSI and CD-ROM drive activity when flashing.
z Power: Indicates power is being supplied to the system's power
supply units. This LED should normally be illuminated when the system is
operating.
z Power Fail: Indicates a power supply module has failed. This should
be accompanied by an audible alarm. A backup power supply module will
take the load and keep the system running but the failed module will need to
be replaced. Refer to Chapter 6 for details on replacing the power supply.
This LED should be off when the system is operating normally.
