DL385 G2 Diagnostic LED's

[Elmer Oltmann, Jr.]

Does anyone know where to find the meaning of the Diagnostic LED's located on the system board? I have an intermittent problem where the system stops during POST and does not give any display or error information, only LED 1,6 & 7 lite.

Been through that whole manual, the only reference to the diagnostic LED's are on page 92 & 93 but it never explains what the LED's mean. It's probably for some engineering usage. It would hang right after the fans cycle after a power on, no display or video via KVM or crash cart attached to the front.

hi

try the normal troubleshoting

-> try the server connect direct to a monitor

- Remove any attached device to the server (storage, ...)

-> after that reseating all the parts.
memories DIMMs, Processors, Power Supply, PPM (power processor modules), PCI riser cage

-> swap components - try different combinations in case you have more that 2 DIMMs or Processors.
- memories, Processors (PPM)

-> Try minimum configuration
-> just 2 DIMMs, 1 processor, no PCI cards, no data cables attached to HDDs.

-> clear NVRAM, using the System maintenance switch

let me know anyhitng about this

I have fixed the problem, bad NIC card... very strange.

But I still would like to know the meaning of the LED's, may have saved a lot of parts swapping, which I do not like to do.

hi Elmer

The DL385 G2 Maintenance and Service Guide is not very clear.  The "Diagnostic LEDs" are iLO's diagnostic LEDs.

See page 182 of:

http://bizsupport2.austin.hp.com/bc/docs/support/SupportManual/c03351063/c03351063.pdf

"After the boot process is complete, the HB LED [LED 8] flashes every second. LED 7 also flashes intermittently during normal operation", "The LED indicators (1 through 6) lightup after the system has booted to indicate a hardware failure. If a hardware failure is detected, reset iLO2".
