WARNING:
Before operating or servicing any part of this product, read the
on page 68.
WARNING:
Keep fingers and conductive tools away from high-voltage areas. Failure to follow these precautions
will result in serious injury or death. The high-voltage areas of the system are indicated with high-
voltage warning labels.
CAUTION:
Power off the system only after the system software has been shut down in an orderly manner. If
you power off the system before you halt the operating system, data may be corrupted.
System control network
All MC990 X server chassis use an RMC which communicates with the chassis board level BMCs within
each SSI. These components in concert are generically known as the system control network.
The Integrity MC990 X system control network provides control and monitoring functionality for each
motherboard, power supply, and fan assembly in each MC990 X server chassis in the system.
The RMC network provides the following functionality:
• Powering the entire system up and down.
• Powering individual MC990 X server chassis up and down.
• Monitoring the environmental state of the system, including voltage levels.
• Monitors and controls status LEDs on the enclosure.
