Why you should not install the blade server into blade bays 6 and 7

The BladeCenter QS20 is a double-width blade and you should not insert it into
blade bay slots 6 and 7 of your BladeCenter. This is because blade bays 1-6 are in
power domain one, but blade bays 7-14 are in power domain two, and the
BladeCenter QS20 cannot straddle two power domains.
What happens if the blade server is accidentally installed into blade
bays 6 and 7
If you accidentally insert a BladeCenter QS20 into blade bay slots 6 and 7, this
does not affect the BladeCenter. This is because each power connector of a
BladeCenter QS20 is connected via a power switch (PowerFET), which means that
as long as the blade is not switched on, the blade does NOT cross-connect the
different power domains.
The Management Module does not allow you to power on a double-width blade in
slots 6 and 7 (the Management Module Web interface allows you to click through
the power on procedure but it does not power on the blade).
The Management Module switches on both the BladeCenters and the blade server's
error LED (yellow LED), but does not display an error message, see Figure 5 on
page 13.
