We have a Bladecenter H chassis (8852) with 6 x HS22 (7870) blades that are working fine. I've just added a new HS23 blade (7875) in slot 7, and although the blade seems to be working ok, I've immediately got a warning light on the chassis and blade, and the AMM is now reporting 'invalid blade/blower combination'.
Having made some basic checks, I can confirm that;
The AMM is running firmware 3.64B (I upgraded this before installing the HS23).
The chassis has 2 x 3KW PSU's in bay 1&2 in PD1. Only about 25% of this power is in use.
All temp/cooling/performance stats are well within bounds
There are two chassis cooling devices in bay 1&2 running at about 50% capacity
I understand that once you get to about 12 blades, then you have to be careful and I might need to upgrade some components, but nothing I can see says that we're anywhere near maxing anything out. I saw there was a bug in AMM 3.62 which can cause this error, but I thought that by upgrading to 3.64 beforehand everything would be good.
So, it looks like the blade will work fine, but I'm not happy about the AMM error. Any workarounds for this?
