Power Supply Modules
The 8U SuperBlade enclosure comes standard with one CMM module (see the
Chapter 4 for details on the CMM module) and either two or four power supplies. See
Appendix A for summary specification details on the power supplies available to the 8U
SuperBlade enclosure.
5-1 Power Supply Modules
The minimum amount of modules required to power the system depends upon the full
complement of blade units installed into an enclosure and the type of switches installed
in the enclosure. An LED on the back of a power supply will be amber when AC power is
present and green when the power is on.
When installing only a few power supplies in the enclosure, they should be installed first
in the lower rather than the upper power bays. This is to provide increased airflow
across the memory modules within each blade module.
The 2200W power supply modules require a 200-240V AC input and a C20 socket,
which requires a power cord with a C19 connector.
Supermicro's high-efficiency blade system power supplies deliver continuous redundant
power up to 94% peak efficiency. Each power supply module includes a management
module that monitors the power supplies and the power enclosure
The features of these power supplies are shown below.
