For the SBE-820C enclosures, three additional cooling fan modules, each with two
cooling fans, are in the rear of the enclosure. Also, additional fan modules are available
for substitution of power supply slots in the enclosure.
NOTE:
In order to prevent air flow leaks that would reduce cooling efficiency in the blade
system’s enclosure, install dummy blades to close off any blade slots that do not have active
blade modules installed in them.
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
Section A-2: Environmental Specifications on
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 8U SuperBlade enclosure comes standard with one CMM module and up to eight
power supplies. Information on the power supplies is summarized below. See
Section 4-1: Chassis Management Module on page 4-3
for details on the CMM module
and
for details on the power supplies.
If you install only four 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. See the table below for details on the
power supplies for the different models of enclosures.
