Appendix F. BladeCenter® power module upgrade guidelines 529
Important:
The HS40 blade server occupies two adjacent bays. When you compl ete the “Power w orkshee ts” on p age 532 ,
enter the power unit value from Table 154 twice, once for each bay that the blade server occupies. If you
install an HS40 blade server in bays 6 and 7, the blade server will use power from both power domain A and
power domain B. In the power worksheets, enter the power unit value twice, once for bay 6 of power domain
A and once for bay 7 of power domain B.
