Chapter 5: Power Supply Modules

Four modules are required when the full complement of 10 blade units are installed into 
an 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 two power supplies in the enclosure, they should be installed in the 
lower rather than the upper power bays. This is to provide increased airflow across the 
memory modules within each blade module.

The 2000W power supply modules require a 200-240V AC input and a C20 socket, 
which requires a power cord with a C19 connector (see 

 below for details). 

The 1400W power supply modules can work with both 110V and 220V AC input and use 
a C14 socket and C13 connector.

Supermicro's high-efficiency blade system power supplies deliver continuous redundant 
power at 90%+ peak efficiency. Each power supply module includes a management 
module that monitors the power supplies and the power enclosure

If a power supply or a fan in a power supply fails, the system management software will 
notify you of the situation. In either case, you will need to replace the power supply 
module with another identical one (part number: PWS-2K01-BR). 

1.

Insert a replacement unit into the empty power bay with the handle to the left.

2.

Push unit all the way in until it is firmly seated.

3.

Push the handle back into the closed position until it clicks into the locked position.

NOTE: Refer to 

 for possible updates on 

part numbers.

WARNING: This left/right orientation depends on the power supply’s top or 
bottom location. If you inadvertently put a power supply upside down in the lower 
slots, it can be VERY difficult to remove the power supply.
