Table 3. Diagnostics panel LEDs (continued).CR LED Description28 FAN A fan failed, was removed, or is operating slowly. This LED is turned on whenany of the following LightPath LEDs mounted directly on the fan assemblies isturned on by the Integrated System Management Processor:1. Fan 1 Failure LED or was removed2. Fan 2 Failure LED or was removed3. CPU1 Fan-sink Failure LED4. CPU2 Fan-sink Failure LED5. Fan 3 Failure LED or was removed29 MEM A Memory failure occured. This LED is turned on by the hardware when anyof the following LightPath LEDs located near the memory DIMMs is turned onby the Integrated System Management Processor:1. CR16 Memory DIMM #1 failure LED2. CR17 Memory DIMM #2 failure LED3. CR14 Memory DIMM #3 failure LED4. CR15 Memory DIMM #4 failure LED30 CPU A CPU failure occured. THis LED is turned on by the hardware when of thefollowing LightPath LEDs located near the appropriate CPU socket is turnedon by the Integrated System Management Processor:1. CR1 CPU #1 failure LED2. CR& CPU #2 failure LED3. CPUx Thermal-trip active or CPU over temperature (TEMP/CPUx/SystemError LEds will also be on in this case.)9 PCI A Error occurred on PCI channel A or the system board. It will be turned on bythe Integrated System Management Processor.10 PCI B Error occurred on PCI channel B or the system board. It will be turned on bythe Integrated System Management Processor based on the informationprovided by SMI BIOS when it detects a low level pulse.67 PCI C Error occurred on PCI channel C or the system board. It will be turned on bythe Integrated System Management Processor based on the informationprovided by SMI BIOS when it detects a low level pulse.22 SP Integrated System Management Processor detected an error.31 VRM A VRM failure occured.21 DASD Hot-swap SCSI planar board or HD failure or was removed on either Standardor optional Expansion Hot swap bay. DASD backplane over temperature (inthis case TEMP/System Error LEDs will be on also.)Remind ButtonYou can use the Remind button to place the front panel system-error light into aRemind mode. By pressing the button, you acknowledge the failure but indicatethat you will not take immediate action. If a new failure occurs, the LED will turnon again.In the Remind mode, the system-error light flashes every 2 seconds. Thesystem-error light remains in Remind mode until one of the following situationsoccur:v All known problems are resolvedInstalling options 41
