• The server supports the following power supply configurations:
– For two processor server configurations, one or more 1600-watt or 1100-watt power supplies.
– For four processor server configurations, two or more 1600-watt or 1100-watt power supplies.
– For eight processor server configurations, two or more 1600-watt or four 1100-watt power supplies
Attempting to operate the server with an unsupported power configuration results in an "unsupported
configuration" message in the system event log and on the system front panel
• Power supplies can be installed in any power supply bay and populated in any order. Redundancy differs
depending on how many processors are installed, the number of power supplies that are required to keep
the system operating, which power supply bays are populated, and the number of input power sources.
Notes:
– For power source redundancy, the power supplies in bays 1 and 3 must be fed from a different power
source than the power supplies in bays 2 and 4.
– Use the Lenovo Capacity Planner to calculate the required power capacity for what is configured for
your server. More information about the Lenovo Capacity Planner is available at:
