IBM System x3850 X5 Implementation Guide

Chapter 8. IBM BladeCenter HX5 445
You might see the following effects of split power domains for HX5 with MAX5 configurations:
򐂰 A loss of power to either power domain results in complete system shutdown.
򐂰 The HX5 will not be able to power on if the attached MAX5 in slot 8 has no power, because
the HX5 treats the entire system as a single unit. You must remove the IBM HX5 MAX5
1-Node Scalability kit to allow the HX5 to resume normal operation if power cannot be
restored to the second power domain that contains the MAX5.
Where possible, avoid placing HX5 4-socket or HX5 and MAX5 configurations across blade
bays 7 and 8.
BladeCenter design: The loss of power to an entire power domain is extremely unlikely
due to the redundant design of the BladeCenter H chassis. We provide this information
merely for guidance in the case of this unlikely event.
