Important:
The HS40 blade server occupies two adjacent bays. When you complete the “Power worksheets” on page 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.
