Chapter 1: Introduction
Middle Plane
The middle plane connects the various capabilities of the blades, such as the Gigabit
(GbE) switch(es) to Network Interface Controller(s), the Chassis Management Module
(CMM) to the USB devices and the InfiniBand Switch to the Host Channel Adapters.
These devices all connect to the middle plane through high density connectors that
provide both signals and power. This type of configuration reduces the amount of
system cabling and simplifies the task of setting up the system. It provides an alternative
signals route to support redundant power, CMM, network and IPMI functions.

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, as

Enclosure Cooling
The cooling for the entire blade system is provided by the fans in the power supply
modules. For example, the 2000W power supply modules have four fans per module,
whereas the 1400W power supply modules have two fans per module. If a power supply
fails, its fans 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
cables), check that all fans are operating normally and make sure the ambient room
temperature is not too warm (refer to
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.

another.
NOTE: You must install dummy power supplies (MCP-650-00001-0N) in any
open power supply slots in order to prevent air flow leaks that would reduce
cooling efficiency in the blade system’s enclosure.
