Oh, thank you very much! Looks like OA is a big boss there... Nothing will be done without it. But if it will not work even without fans I doubt I will benefit from acquiring OA module alone. I still will need fans and maybe something else. Basically full enclosure without enclosure The basic idea here is to use bare minimum. I mean really minimum Ok, thank you once again, need to rethink all that info. Anyways blade and midplane with switch are already coming. I'll try to play with that first before ordering something more. Let's see what I will be able to achieve though...A few tests and some initial results:
Test 1 - 1 Blade, 1 PSU, 1 Gbe pass-through module - no OA module, no Fans
- psu turns on and supplies 12V to the chassis, psu led green
- blade power led amber -> standby
- no signs of life in the pass-through module or Insight display (was to be expected w/o OA)
- any attempt to power on the blade results in blade health led blinking red -> critical condition and psu shutting down (led going from green to amber -> power supply failure)
Test 2 - 1 Blade, 1 PSU, 1 Gbe pass-through, 4 fans (minimum config) - no OA
- psu turns on - > green led
- blade power led amber -> standby
- all 4 fans run at full blast
- no signs of life in pass-through or Insight
- any attempt to power on blade results in blade health led blinking red -> critical condition
- psu stays on -> led green
Test 3 - 1 Blade, 1 PSU, 1 Gbe pass-through, OA module installed - no fans
- psu turns on - > green led
- blade power led amber -> standby
- Insight display turns on showing fan subsystem failure, wants at least 4 fans installed
- Blade health led blinks red even without trying to power it on - > critical condition
Test 4 - 1 Blade, 1 PSU, 1 Gbe pass-through, OA module and 4 fans installed
- psu turns on - > green led
- blade power led amber -> standby
- Insight display turns on showing all green -> happy with the situation
- Blade powers on (led amber -> green)
- Both link and network activity on the pass-through module
So it looks like you have to bite the bullet and get the OA, unfortunately....
