I’m looking for assistance from anyone who might be familiar with troubleshooting Max IMPACT issues.

I’m attempting to boot an Indigo2 R4400 IMPACT system with a Max board set installed. The issue presents as the computer starting, playing the boot tune, and then hanging (led green to solid orange).

I can tell the machine is attempting to get the graphics running: the screen pops up with signal detected and then goes blank about three seconds later. This continues to happen over and over until power is removed.

I have so far accomplished the following troubleshooting:

1) Pull and reseat everything in the machine
2) Disassemble the board set (wearing ESD gloves)
2b) Clean all contacts, inspect every board for missing SMD components, reassemble and ensure all boards are mated (Note: No TRAMs are present or installed)
3) Swap in a Solid IMPACT board: machine boots with no issue
4) Swap in an Extreme board set: machine boots with no issue
5) Machine passes IDE with Extreme board set installed

With all that said I’m a bit stuck. Is it a common failure mode for the board set to just stop working?

I’m hoping someone might have experience with resurrecting this set as I’d like to migrate it to my R10K IMPACT system.

Thanks!
