RS/6000 Diagnostic LED numbers and codes

[pgilli]

Hi,
I have 2 old AIX server (oslevel 4.3.3.0) with boot problem

The 1st hang during boot, with code "632" on led display.

The 2nd hang during boot, with code "bed" on led display.

I'm searching information for these code.
How to solve the problem?

Please, can you help me?
Thankyou
Paolo

632: 25 Mbs Charm 1.5 ATM adapter being configured. I suggest you remove the power lead, then this adapter, then try again.

Select Miscellaneous, LED, 2E6-2530 Configuration Program Indicators.

bed: seems unlikely, are you sure the LED display is working correctly? Could it be 888 but with a few LED display segments not working? press the yellow reset button and see if it changes, if so record the new number and then keep pressing and recording until you get back to 888, or bed in your case.

Link to the hardware docs:

You should probably start with this book and the "start of call" map:

To determine if your systems are "Micro Channel" or "Multiple Bus" either post the machne type and model or as a general rule:

7009 to 7015 are Micro Channel.
7017 and higher are multiple bus.
