LEDs

Two LEDs are located at the right top of the enclosure above the last or right most blade.
The left LED provides Power Status information and the right LED is the Fault LED.

Enclosure Cooling

The cooling for the entire blade system is provided by the fans in the power supply
modules. For example, the 1600W power supply modules have one fans per module. If
a power supply fails, its fan will continue to operate to provide continuous cooling. For
this reason, a failed power supply should remain installed in the enclosure until a
replacement unit is ready.
For overheat problems, check that there are no obstructions (such as poorly routed
cables), check that all fans are operating normally and make sure the ambient room
temperature is not too warm (refer to
page A-6 for the maximum operating temperature). You can also use either of the blade
management software utilities to increase the fan speed and maximize system cooling.
In the event of a power overload, you will have to add additional power supply modules
to take up the load. Otherwise, you will not be able to power up all the blade modules.
The blade BIOS plus CMM firmware calculates the load to determine if the power
supplies can adequately handle the total system configuration.

Power Supply Features

The MicroBlade enclosure comes standard with one CMM module and either two or four
power supplies. Information on the power supplies is summarized below. See
Section 4-1: Chassis Management Module on page 4-2
and Chapter 5 for details on the power supplies.
If you install only two power supplies in the enclosure, they should be installed in the
lower rather than the upper power bays. The reason for this counter-intuitive installation
is that the power supplies in the lower bays provide increased airflow across the
memory modules within each blade module.

Power Supply Modules

Each power supply module has its own power cord. Four modules are required when
the full complement of blade units are installed into an enclosure. An LED on the back of
a power supply will be red when AC power is present and green when the power is on.
Supermicro's high-efficiency blade system power supplies deliver continuous redundant
power up to 95% peak efficiency. Each power supply module includes a management
module that monitors the power supplies and the power enclosure.

Power Cord

Each power supply module has a C-14 type socket (IEC-60320-C14) for AC power and
the power cord must have a C-13 type connector (IEC-60320-C13) to connect to the
power supply.
